CROP BIOTECH 12/8/06, 12/15/06 AND 12/22/06
Growing Biofuel Crops in Abandoned Industrial Sites
The use of marginal lands for biofuel crop plantations is seen as a move to increase the land base of biofuel crops as the future demand of the commodity increases. Biofuels crops can be planted in abandoned industrial land sites, rendered marginal/unproductive by soil contamination with industrial pollutants for two objectives: biofuel feedstock production and bioremediation. Bioremediation, the use of plants to remove or degrade contamination from soils and surface waters, has been proposed as a cheap, sustainable, effective and environmentally friendly alternative to conventional remediation technologies.
Scientists at Michigan State University (MSU), in partnership with Daimler-Chrysler, are exploring the possibility of utilizing industrial landsites (“brownfields”) for growing corn and switchgrass as bioethanol feedstocks, and soybeans, sunflower and canola as biodiesel oilseed crops.
The study area is a former industrial dump site in Oakland County. The team, lead by MSU professor, Kurt Thelen, is determining whether crop yields are sufficiently high to make the strategy viable. At the same time, they are also investigating whether biofuel crops can remove contaminants from the soil, and whether this remediation capability affects the quality of the crops for biofuels use.
Biotech Switchgrass for Cheaper Ethanol
Dr. Albert Kausch, a plant geneticist from the University of Rhode Island, says that genetic engineering of switchgrass as bioethanol feedstock could significantly reduce the cost of ethanol production from the present $2.70/gallon to $1/gallon. Switchgrass has several advantages for the use as bioethanol feedstock, including the ability to grow in marginal soils with little agricultural inputs like fertilizer, irrigation and insecticides. However, the slow breakdown rate of the cellulose content prior to ethanol fermentation of unaltered switchgrass, limits the commercial profitability of this crop for ethanol production. At present, Dr. Kausch is working with professors at Brown University to develop better enzymes for cellulose degradation in switchgrass, and hopes to come up with improved varieties by 2011.
Philippine Bicameral Legislative Assembly Approves Biofuels Bill
The Philippine’s Biofuels Bill has finally been approved in a joint bicameral (Senate and Congress) committee. The bill provides for the mandatory use of biofuel blends in gasoline and diesel fuels. At least five percent ethanol blend in gasoline is targeted within two years of effectivity of the bill, and then increased to ten percent four years after the passage of the law. A minimum of one percent of biodiesel blend is also mandated upon effectivity of the law’s implementing rules and regulations; this would be increased to two percent within two years.
Presently, gasoline with ethanol and diesel fuel blended with coconut-based biodiesel are sold in the Philppines, but only on a voluntary basis. The passage of the law is expected to fuel the construction of bioethanol and biodiesel plants in the country. Biofuel crops will be sugarcane, cassava, and corn as the feedstocks for bioethanol production, while coconut will be used to produce biodiesel. Among the benefits from the passage of the bill are: (1) an annual savings of about 35 billion pesos (roughly $700M) in fuel imports, (2) increased employment (3) increase in farmer income, and (4) improved air quality.
ENERGY CROPS AND FEEDSTOCKS FOR BIOFUELS PRODUCTION
Algae as Biodiesel Feedstocks
Researchers from the South Australian Research and Development Institute (SARDI) are undertaking research programs on the culture of microalgae for biodiesel production. Microalgae are an attractive feedstock for biodiesel production because is its oil producing efficiency (up to 30 times higher per unit area of land relative to oil seed crops), and they can be cultured in poor quality saline water or effluents with high nutrient load. It is also said to contain a total oil content of 60% to 70% (dry weight basis). In addition to microalgae, SARDI is also looking into development of other feedstocks for biodiesel like canola and mustard.
Information Resources on Algae-based Oils for Biofuels Production at “Oilgae” Website
Oilgae.com is a website containing interesting and useful information for researchers, students, traders and manufacturers who are interested in algae-based oils for biofuels. Among the information available are: (1) dry weight compositions/oil content of some algal species, (2) oil composition of algae relative to seedoils, (3) genetic engineering of algae to increase oil production, (5) large scale algae biodiesel production, (6) the Biodiesel Algae Reference.
Handbook of Energy Crops
This site by provides useful information on about 200 plant species which can be used as energy crops. Although only the scientific names of the plant species are provided, the information is detailed and comprehensive.
Coconut Methyl Ester (CME) Described as the “Perfect Diesel”
A paper by R.S. Diaz, Jr. and F.C. Galindo of the Asian Institute of Petroleum studies describes the reasons why or coconut methyl ester (CME), derived from coconut oil, is close to that of an ideal diesel fuel. An ideal diesel fuel is said to be 100% n-paraffins (saturated hydrocarbons), which gives its chemical stability (i.e., not prone to oxidation or bacterial degradation), easy burnability and low nitrogen oxides (NOx) emissions. The paper reports that CME is 91% saturated, which makes it very close to an ideal diesel fuel. A comparison of CME with other biodiesel fuels from palm oil, Jatropha and soybean is also shown.
BIOFUELS POLICY AND ECONOMICS
Oilseed Production Increasingly Geared Toward Biodiesel
According to the Production Estimates and Crop Assessment Division, Foreign Agricultural Service of the U.S. Department of Agriculture, world interest and demand for biodiesel production (for motor and heating fuel) is increasing. Europe is said to be the main area for large volume production, and is still expanding. Brazil’s Probiodisel Program is looking into oilseed feedstock like soybean, palm, coconut, castor seed, cottonseed and sunflower. Soybean is reportedly the main commodity in Brazilian oilcrop production and is well advanced in research. Although it is seen as the most likely viable option for a biodiesel industry, other options in the country’s North and Northeast are being considered. These options include castor and palm oils.
The Philippines is mentioned as the first country to develop coconut oil (including coconut oil methyl esters) for use as transport fuel. Presently, the use of one percent coconut biodiesel blends is required for use in government vehicles. In the United States, soybean is the main feedstock for biodiesel production. Biodiesel service stations are available in some States, and some vehicles are also reported to run on biodiesel.
Global Renewable Fuels Outlook to 2010
The document provides a comprehensive review of biofuels policy initiatives in selected countries in Asia Pacific, Europe and the Americas. According to Hart Energy Consulting, who produced the document, “critical factors influencing demand such as public policy initiatives, vehicle compatibility and the interface with conventional fuel quality specifications are reviewed, together with the proposed production capacity to forecast the apparent various biofuel supply/demand balances in the world-wide gasoline and diesel fuel markets, for the period 2005 – 2010”.
NATIONAL LEVEL ALLIANCES AGAINST HUNGER INCREASING, SAYS FAO
The Food and Agriculture Organization (FAO) reports an increasing number of national groups that are joining the International Alliance Against Hunger (IAAH), a voluntary association of local, national and international organizations that are working together to solve problems related to food security.
“With 49 national-level alliances currently operating under the IAAH aegis and many more countries expressing interest in joining the movement, momentum is clearly increasing to involve more people from more walks of life,” says Hervé Lejeune, FAO Assistant Director-General for World Food Summit Follow-up.
The international alliance was established by FAO in 2003. FAO provides examples of activities that have been made by countries such as Brazil’s Zero Hunger Strategy, Nicaragua’s support to family and school gardens, and Ghana’s school feeding program.

CEREAL PRICES HIGHEST IN DECADE
Prices of cereal grains such as wheat and maize have surged to highest levels not seen in the last decade, says the Food Outlook report from the Food and Agriculture Organization (FAO). This is attributed to poor harvests in major grain producing countries and an increasing demand for biofuel production.
Production of coarse grains in 2006 currently stands at 981 million tons, a decrease of 2.1 percent from 2005 figures. World wheat production went down by 5.3 per cent of 2005 figures. No growth was registered by rice production which was affected by natural calamities worldwide.
FAO predicts that higher prices will probably encourage more plantings in 2007. However, with grains being used for industrial purposes such as ethanol, prices may continue to remain high.

ENGINEERING WILT-RESISTANT BANANAS FOR AFRICA
Millions of farmers in East Africa are dependent on banana for their livelihood. Unfortunately, bananas in the region are susceptible to the banana xanthomonas wilt (BXW) disease, which attacks all banana varieties resulting in absolute crop loss. Measures for managing BXW are already in place, but only a small percentage of the farmers are aware of these practices. Thus scientists from the International Institute of Tropical Agriculture (IITA) are spearheading the development of wilt-resistant bananas to counter the spread of the disease. IITA will be working with Uganda's National Agricultural Research Organization, the Kenya-based African Agricultural Technology Foundation, and Academia Sinica in Taiwan in this project.
One approach being explored is to transform farmer-preferred banana cultivars by introducing a resistance gene from sweet pepper. Priority has been given to the major farmer-preferred banana varieties, including Kayinja. The improved varieties will be tested rigorously for efficacy against BXW and for environmental and food safety in compliance with regulations of each of the countries where such bananas could be grown and consumed.

NEW MAIZE VARIETIES FOR KENYAN FARMERS
To improve the livelihood of African farmers, scientists based at Kenya Agricultural Research Institute (KARI) and working within the Maize Breeders Network (MBNET) have been developing new maize varieties for commercialization. During a recently convened National Performance Trial Committee meeting in Nairobi, Kenya, ten improved maize varieties bred by KARI were recommended for pre-release or full release. The varieties produce higher yields than those currently grown by farmers, are also tolerant to drought and resistant to maize streak virus disease, stem borer damage, and leaf blight and gray leaf spot.

STRIGA-RESISTANT MAIZE FOR COMMERCIAL RELEASE IN KENYA
Following extensive tests and farm trials, Striga-resistant maize, known in Kenya as Ua Kayongo, is now made available to small-scale farmers. The Partnership to Control Striga in Kenya has organized an event in Kisumu City, Kenya on 13-15 December 2006 to facilitate the commercial release of Ua Kayongo maize. The Partnership is led by Agricultural Technology Foundation, BASF, International Maize and Wheat Improvement Center (CIMMYT), and Forum for Organic Resource Management and Agricultural Technologies (FORMAT) in collaboration with a network of non-government organizations, seed companies, Kenya Agricultural Research Institute (KARI) and farmer associations in Kenya.
The new herbicide-resistant maize hybrid and seed coated herbicide technology is based upon inherited resistance of maize to a systemic herbicide (imazapyr), a mechanism widely recognized as imazapyr-resistance (I-R). When I-R maize seed is coated with the herbicide, Striga attempting to parasitize the resulting plant are destroyed. Imazapyr is marketed to Kenyan seed companies producing I-R Ua Kayongo maize (mixed vernacular for Striga killer) under the trade name Strigaway.

A RESEARCH NETWORK FOR SUSTAINABLE COCOA PRODUCTION IN AFRICA
Cocoa farming is central to West Africa: Ghana and the Ivory Coast alone provide nearly 60% of the total world production, and a large proportion of the rural population depends on this crop for their living (6 million people in Ghana alone). However, cocoa farming in the region is facing a difficult time, as soil nutrients are depleted from older plantations due to shortages of fertilizers, and as the pressure of plant pests and parasites increase. These difficulties are pushing farmers to turn to forests in search of more productive land, a practice that will have serious economic, environmental and social implications
How can the sustainable production and exportation of this important crop be promoted? To this aim, CIRAD, a French agricultural research centre working for international development, has established an African Research Network, which falls under the auspices of the Cocoa Producers Alliance (COPAL) and the West and Central African Council for Agricultural Research and Development (CORAF/WECARD). The network comprises 35 researchers from 32 research and development organizations in the leading five cocoa-producing countries in Africa: Ivory Coast, Ghana, Togo, Nigeria and Cameroon.

ARGENTINA BETS ON BIOTECHNOLOGY
How is biotechnology shaping Argentina’s productive economy? An interdisciplinary team of researchers, with the support of the Secretariat for Science and Technology of Argentina, and the National University of de General Sarmiento (UNGS), set out to answer this question. The researchers reviewed 84 national biotech companies to determine gains in terms of sales, foreign trade and employment, and to review the innovations adopted. The companies fall in three main categories: agricultural production (54 companies), which include the development of improved new seed varieties; health; and food processing.
The study shows that Argentina occupies number 8 in the list of economies investing in biotechnology, where the USA takes the lead with 1159 biotech companies, followed by Canada with 389. The majority (80%) of the Argentinean companies are small to medium businesses with one or two biotech products, supported by national investments. Between 2003 and 2004, the biotech private sector invoiced 950 million Argentinean pesos (about US$ 310 million), and gave employment to 5000 people, 11% of which involved in R&D. “This is very significant in terms of national investment in the area, especially taking into account the nation’s economic turmoil in recent years”, said Roberto Bisang, UNGS economist. “Biotechnology can be defined as the industry of industries, as it is able to substantially promote several productive sectors of the economy”, added Bisang.

HARVESTING CORN AND STOVER IN A SINGLE PASS
Iowa State University researchers are testing a combine that can harvest grain and cut the remaining stover (stalks, cobs and leaves) in a single pass in the field. The prototype harvester works by dumping a crop of corn kernels into the combine's hopper and blowing the stalks, cobs and leaves into a trailing wagon. For farmers, they will only need the stover attachment which they can use on a standard combine.
Corn stover was identified to be an additional source of biomass. Cellulose from stover can be converted into ethanol and thus could feed the next generation of ethanol plants. Stuart Birrell of Iowa State University said that the supply of stover from the field will help the U.S. bioeconomy by providing supply to biorefineries.

CSIRO IDENTIFIES MARKERS FOR WHEAT RUST RESISTANCE
Australia’s CSIRO Plant Industry researchers have discovered a DNA marker for two important rust resistance genes in wheat, Lr34 and Yr18. These two genes are often inherited together and provide wheat plants with improved protection against leaf rust and stripe rust – two major diseases of wheat in Australia and worldwide.
CSIRO scientist Evans Lagudah said that the DNA marker is 99 percent effective in determining the presence of Lr34 and Yr18 in different wheat from Australia, India, China, and North America. The markers are now being used in Australia and worldwide.

NEW ZEALAND TO REVIEW GM IMPORT STANDARDS
New Zealand’s Ministry of Agriculture and Forestry (MAF) has commissioned this week an independent enquiry into the circumstances surrounding the importation of sweet corn seeds containing low levels of genetically modified materials. The enquiry is intended to assist MAF to strengthen its processes and procedures and prevent future incidences. MAF’s objective is to ensure that the country’s GM-free status is maintained.
MAF tracked where all the corn seeds that was inadvertently cleared by its Quarantine Service went and where they were planted. After testing, MAF announced last week that it has cleared the country’s Mid-Canterbury and Hawkes Bay region for absence of genetically modified materials. These regions have Krispy King and GH2042 sweet corn varieties. However, seed tests for the Jubilee Plus/Dominion consignments planted in the Gisborne and Hawkes Bay regions have produced positive results and the crops there will be destroyed.

THAILAND: IMPORTS OF GM CROPS ON THE RISE
Vithet Srinet, from the Office of Policy and Planning, Ministry of Natural Resources and Environment of Thailand has indicated that the import of genetically modified (GM) agricultural products to the country, such as corn and soybean, is on the rise. Soybean import went up from 418,788 ton in 1996 to 1,435,801 ton in 2004. In 2007 Thailand is predicted to import 1.7 million ton worth 12,000 million Baht (US$340.7 million), and 85% of these imports will be GM. Imported soybeans are mainly used for oil extraction and for animal feeds, and a small amount is used in the food industry to produce bean curd and soybean sauce.
Mr. Setasan Setakarun, President of Soybean Oil Producer Association, has asked the government to review the Thai GMO policy, indicating that there are several markets open for biotech products, and that GM and organic markets can coexist.

STUDY SHOWS GROWING ACCEPTANCE OF GREEN BIOTECH IN SWITZERLAND
A study conducted between 2000 and 2006 by DemoSCOPE, a polling institute based in Adligenswil, Switzerland, confirmed that resistance to the application of gene technology in agriculture is steadily and slowly declining in Switzerland. With a representative selection of 2,008 interviewees from German- and French- speaking regions, the 2006 poll showed that 45 percent were against the use of gene technology in agriculture, 31 percent advocated it, while 24 percent were still undecided. The number of respondents expressing negative attitude towards gene technology has decreased from 58 percent in 2000.
The most important differences in the single population groups concerned the French-speaking region in which opponent (31%) and advocate (33%) were almost equally strong. Generally, greater acceptance of gene technology in agriculture was notable among interviewees under the age of 30. The statistical reduction of resistance towards agricultural applications may be attributed to better information: through increasing global experience with green gene technology, individuals originally identifying themselves as opponents have become more broadly informed. However, the increase in undecided individuals may point to the need for further public information.

CONTROL OF PSEUDOMONAS-CAUSED DISEASES IN FRUIT TREES REVIEWED
Bacterial canker, blossom blast, and apical necrosis are some of the diseases caused by the Pseudomonas bacteria These pests cause significant damage to fruit trees, severely reducing crop yields or even killing the plants.
In a recent article in the journal Plant Pathology, Megan Kennelly and colleagues presented a review of the progress made in controlling these pests. The paper provides an overview of several Pseudomonas-caused diseases of fruit trees, discusses the current and emerging understanding of virulence factors such as toxins, phytohormones, and effectors in these diseases, and also presents the current and possible future management strategies.
The authors suggest that comparative genomic analyses and genetic studies are important in adding knowledge that will lead to improving host resistance, and may also lead to the development of transgenic fruit trees. This would be the best approach since current conventional methods cannot adequately control the disease.

GENE FLOW FROM GE TO CONVENTIONAL MAIZE IN REAL SITUATIONS OF COEXISTENCE
The concept of coexistence has been established as 'the principle that farmers should be able to cultivate freely the agricultural crops they choose, be it genetically-engineered (GE) crops, conventional, or organic crops'. The effect of cross-pollination on coexistence is usually evaluated in field trials that were designed by planting a nucleus of maize (GE or a cultivar with a special phenotypic trait) and then studying the occurrence of cross-fertilization in an adjacent field. In most trials, both genotypes had been sown at the same time to increase synchronicity of flowering, in order to detect cross-fertilization in the worst situation that could be found in an area in which GE and non-GE maize coexist. However, could these results be applied to real situations of coexistence?
A recent study was conducted in real situations of coexistence in which GE and non-GE maize fields are sown with different cultivars, with different sowing dates, mixed with other crops, and with different barriers that may influence pollen dissemination. In this study, two crop regions located in Catalunya, Spain were chosen during the 2004 growing season in which irrigated transgenic Bt (resistant to the corn borer attack) and conventional maize fields coexisted with other crops. Five conventional fields in the Térmens area and seven in the Foixà area were chosen to detect and quantify the rate of cross-fertilization. In general, the rate of cross-fertilization was higher in borders and decreased towards the center of the field.
Results obtained in this study perfectly match those obtained in field trials specially designed to study pollen mediated gene flow in maize.

PLAN FOR FOOD SAFETY, ANIMAL AND PLANT HEALTH ASSISTANCE AGREED
Developing countries will soon receive assistance in implementing internationally agreed standards for food safety and animal and plant health, after international organizations, donors and representatives of beneficiary countries approved a new medium-term strategy to strengthen the Standards and Trade Development Facility (STDF).
The STDF was created in 2002 as a trust fund by five organizations: the United Nations Food and Agriculture Organization (FAO), the World Bank, the World Health Organization (WHO), the World Organization for Animal Health (OIE) and the World Trade Organization (WTO). The new strategy for the STDF aims to advance capacity-building efforts. It places much greater emphasis on the facility acting as a vehicle for coordination, fund mobilization and the identification and dissemination of best practice in the provision of sanitary and phytosanitary (SPS)-related technical cooperation and capacity building.
Developing countries are expected to gain and maintain market access, and improve domestic human, animal and plant health standards through this joint effort.

GM COTTON AND SUGAR BEET CERTIFIED REFERENCE MATERIALS
The Institute for Reference Materials and Measurements (IRMM) recently released reference materials for the analysis of genetically modified (GM) cotton seed and the sugar beet H7-1 (ERM-BF419).
The GM stacked cotton event, developed by Dow AgroSciences has been genetically engineered to contain two new proteins which provide resistance against certain lepidopteran pests, and another protein which served as a selectable marker during the development of the biotech cotton variety.
The GM sugar beet event H7-1, on the other hand, was jointly developed by Kleinwanzlebener Saatzucht (KWS) and Monsanto. The sugar beet H7-1 contains the epsps gene isolated from a strain of the microbium Agrobacterium. The EPSPS protein provides tolerance to Roundup® herbicides containing glyphosate.

ROLE OF BIOTECH IN NATIONAL DEVELOPMENT REVIEWED
Biotechnological tools have been used to provide food and contribute to socio-economic advancement and national development, says Nigerian scientists Iheanyi Okonko and colleagues.
Their review, published by the African Journal of Biotechnology, provides an overview of the status of plant, animal, and microbial biotechnologies, as well as possible applications in developing countries.
Okonko and colleagues stressed that biotechnology innovations have specifically contributed a lot to food processing. Among its contributions include the enhancement of product quality and safety, and in providing improved ingredients and raw materials.
However, some of the issues in developing countries need to be addressed. These include intellectual property rights, cultural factors, and the appropriateness of the technology in a developing country setting. More importantly, developing countries should weigh up their investments in biotechnology against other potential uses of these resources.

NIGERIANS STAND TO GAIN A LOT FROM BIOTECHNOLOGY
Biotechnology could easily provide good jobs for millions of unemployed Nigerians under the biotechnology bioresources programs, said Sam Wuyep a director at the Nigerian Biotechnology Development Agency (NABDA), Abuja, during a biotechnology awareness workshop on Thursday 14th December, 2006. Bamidele Solomon, Director General of NABDA added that the government should as a matter of priority initiate steps to explore the use of biotechnology for the benefit of Nigerians and thus ensure that the country becomes one of the global leaders in the field.
Most importantly, modern agricultural biotechnology applications are an essential tool for agricultural development for food security, income generation and poverty alleviation. Christian Fatokun, from the International Institute of Tropical Agriculture (IITA), explained that in spite of several years of research work it has become impossible for IITA and other advanced laboratories to develop improved cowpeas and cassava resistant to certain pests and diseases through conventional breeding. Fatokun added that IITA has acquired the knowledge to use biotechnological tools to improve cowpea and other crops without the use of environment unfriendly pesticides.
The workshop was organized by IITA in collaboration with the Cross River State Ministry of Agriculture and NABDA, the workshop was sponsored by the United States Agency for International Development (USAID).

ARS DEVELOPS LOW-PHYTATE WHEAT
The Agricultural Research Service (ARS) of the United States Department of Agriculture has developed low-phytate breeding lines of wheat which can produce flour with 25 times more magnesium than commercial varieties. Low levels of phytic acid may also increase the uptake of magnesium by humans and animals. Magnesium deficiency has been linked to health problems like osteoporosis and Type 2 diabetes.
Researchers led by Edward Souza said that the development of low-phytate wheat is a natural way to improve nutritional content of the grain since magnesium is not usually added to refined flours.

GM TOBACCO WITH INSECTICIDAL PROPERTIES
Researchers at the University of Florida Institute of Food and Agricultural Sciences have genetically modified a tobacco mosaic virus to make it produce a natural, environmentally friendly insecticide which can kill pests that consume the inoculated plant’s leaves.
The tobacco mosaic virus on its own is known to cause severe crop losses. It attacks not only tobacco, but also other plants in theSolanaceae family – including tomatoes, eggplants, bell peppers and potatoes. It causes mottling and discoloration of the leaves, and it can cause death. However, the genetically modified virus contains a chemical known as trypsin-modulating oostatic factor, or TMOF. This chemical is a hormone produced by the ovaries of female mosquitoes, and it stops insects from producing a crucial digestive enzyme called trypsin. As a result, the insects starve to death, as they become unable to draw nutrients from food.
Harvested plants infected with the modified virus can be processed to make mosquito control products.

BRAZILIAN AG MINISTER TO APPEAL AGAINST GM MAIZE STATE BAN
Luis Carlos Guedes Pinto, Brazilian Minister for Agriculture, Livestock and Food Supply, has announced that the government will appeal to the General Law of Union (Advocacia Geral da União- AGU) to revert the decision of the Federal Justice of the Paraná banning the commercial release of biotech maize in the state. The ban was requested by NGO Terra de Direitos (Land of Rights), the Brazilian Institute of Defense of the Consumer (Idec), and the Appraisal and Services in Alternative Agriculture Projects (AS-PTA), on the grounds that no public consultation had taken place on the commercial release of the genetically modified (GM) crop.
According to the Minister, there is no need for public consultation as the biotech crop had already received approval by Brazil's National Technical Committee on Biosafety (CTNBio). “We strongly invest in science and technology so that our agriculture is increasingly sustainable over time, from social and environmental points of view, and to increase its competitiveness. Decisions like this one harm the development of Brazilian agriculture,” said Guedes Pinto.

PEW INITIATIVE: BIOTECHNOLOGY AND THE WINE INDUSTRY
The Pew Initiative on Food and Biotechnology and the American Vineyard Foundation held a workshop in San Francisco, California to examine issues relating to the potential adoption of biotechnology in the winegrape and wine industries. Grape growers, winemakers, grape and yeast research scientists, federal and state government representatives and agricultural commodity and specialty crop producers took part in the event to discuss the scientific, regulatory and marketing issues associated with the potential development of genetically engineered (GE) winegrapes.
Some of the key issues tackled in the proceedings include:
The advantages in production for winegrape growers and vintners that may be realized using agricultural biotechnology, which must be balanced against the need to ensure environmental and food safety.
The willingness of wine consumers, particularly those in overseas markets, to embrace products derived from biotechnology.
The timely discussions on GE yeasts for use in winemaking that have already been developed, and have successfully undergone regulatory scrutiny in the U.S. and Canada, and are ready for commercialization.

NO TO CORN FOR BIOFUEL, SAYS CHINA’S AG MINISTRY
China’s Ministry of Agriculture (MOA) said this week that it is not supporting the use of corn and grain crops for biofuel production until it is able to provide enough food for the country’s 1.3 billion people and feed for its livestock industry.
MOA is instead encouraging the people to grow sorghum, cassava and other non-grain crops on areas that are unfit for grain production. This will keep the current grain growing areas devoted to food and feed production.
China is still committed to substantially raising the share of ethanol and other cleaner-burning substitutes in the coming years. MOA has been testing the production of biofuels on small-scale initiatives using non-grains. It also has approved several projects to develop new types of non-grain plants specifically for use as biofuels.

HUNGARY APPROVES “COEXISTENCE REGULATION”
The Hungarian Parliament has approved the country’s “coexistence regulation”, officially known as the Amendment of the Act on Gene Technology Activities. The new regulation imposes a “de facto” ban on biotech production due to neighbor consent requirements and excessive isolation distances.
The United States Department of Agriculture Foreign Agricultural Service Grain Report adds that deliberations in the Parliament have heightened discussions and activities from different sectors in society. These include a farmers’ forum on crop varieties bred by gene technology; and a Parliament conference on the agricultural gene technology – first generation genetically modified plants. While opposing issues were raised, sectors voiced the need for biotechnology research in the country.

EFSA OPENS PUBLIC CONSULTATION ON GMO FEEDING TRIALS
The European Food Safety Authority recently launched a public consultation on the use of animal feeding trials to assess the safety and nutritional value of genetically modified (GM) food or feed. This aims at providing further guidance on risk assessment approaches for GM food and feed. According to the GMO Panel, any risk assessment of GM food/feed should first consider whether initial studies using in silico and in vitro approaches may answer some of the safety questions and indicate whether there is a need for subsequent in vivo studies, such as animal feeding trials.
Comments are invited by January 31, 2007 on the consultation on animal feeding trials, which is available athttp://www.efsa.europa.eu/en/science/gmo

IMPLICATIONS OF BIOTECH CROPS ON GENETIC CONSERVATION
Many are concerned that the increasing production of biotech crops poses potential problems to biodiversity through gene flow and subsequent introgressions of transgenes. To address this, scientists from Bioversity International (previously known as the International Plant Genetic Resources Institute or IPGRI) and CATIE (Tropical Agricultural Research and Higher Education Center) have assessed the potential impact on the genetic diversity in genebanks and farmers’ fields.
Jan Engels and colleagues wrote in their paper, published by the journal Genetic Resources and Crop Evolution, that precautionary measures have to be taken to mitigate these risks. There is also a need for effective and efficient plant genetic resources conservation efforts. The scientists urged that germplasm curators should conduct routine evaluation to determine the integrity of landraces and crop wild relatives in genebanks. Engels and colleagues used the Central American and Mexican centers of crop genetic diversity as a “case study”.
Their recommendations include: increasing the awareness on the potential risks related to the release of transgenes into centers of crop origin or diversity, and involving an international seed organization (such as the International Seed Testing Association -ISTA) to oversee seed testing and guarantee the adoption of standards on the acceptable level of transgenes in conventional seeds.

NEW METHODS TO HELP IN RE-SEQUENCING GENOMES
DNA sequencing has provided the reference sequence information for many organisms, including many plant species. This has spawned many new studies on determining genetic variation to understand evolution, pathogenicity, and complex diseases. Thus, scientists are re-sequencing those genomes that have been sequenced before.
David Bentley wrote in a review, published by the journal Current Opinion in Genetics and Development, that re-sequencing is an essential biological research activity for studying genes, genetic variation, and gene function. However, re-sequencing has been limited until now by cost and throughput levels of the current technologies.
New methods are however already in different stages of development. These are expected to significantly bring down the cost of obtaining nucleotide sequences. Bentley’s review discusses the new methodologies that can be used. These include: microelectrophoresis, sequencing by hybridization, sequencing by synthesis on arrays, and single nucleotide sequencing. These methods are expected to provide the same (or higher) accuracy and throughput as the current methodology of sequencing.

TILLING FOR PLANT BREEDING
TILLING (Targeting Induced Local Lesions in Genomes) is a general reverse-genetics strategy that is used to locate induced point mutations in genes of interest. This genetic technique has found applications in both model organisms and economically important plant and crop species.
Chinese scientists have reviewed why TILLING is a powerful tool for gene discovery, analysis of DNA variation, and plant improvement. De-Kai Wang and colleagues wrote in their paper that among the advantages of the method is the simplicity in its methodology, requiring no complicated manipulations and expensive apparatus. Also TILLING has high sensitivity, and high efficiency in detecting mutations.
For plant improvement, Wang and colleagues note that TILLING has two immediate applications: a) as a tool for detection of genetic loci that are putatively associated with agronomically important traits, and b) as a tool in establishing a large collection of alleles at genetic loci for the traits of interest.
