Global

Policy makers, rural development practitioners, producers, civil society and the agricultural and scientific community will converge in Copenhagen on December 12, 2009 to  discuss "The road after Copenhagen: priority strategies and actions for ensuring food security and rural development in the face of climate change". The event will highlight the importance of agriculture in climate change and to identify priorities for global agriculture and food security. A workplan with strategies and actions to fully incorporate agriculture into the post-Copenhagen agenda will be developed.

Agriculture and Rural Development Day is being sponsored by a large consortium of organizations, which includes the Consultative Group on International Agricultural Research (CGIAR), the Alliance of the CGIAR Centers and the CCAFS Challenge Program.

The Agriculture and Rural Development Day coincides with the United Nations Climate Negotiations (UNFCCC COP-15).   A series of events from December 7-18, 2009 will be held during the UNFCCC COP-15. According to the CGIAR, they, along with key partners "will make the case that, while agriculture is part of the problem – contributing about 14 percent of total greenhouse gas emissions and accounting for most of the 19 percent contributed by deforestation – it must also be part of the solution."

Bananas are withstanding the impact of the global financial crisis more than other agricultural commodities, the UN Food and Agriculture Organization (FAO) said in a new report. The report predicts that developing countries will continue to register an increase in demand for the fruit, with imports seen to rise 2.5 percent to 2.33 million tons in 2009, driven largely by China. FAO also said that if the recession bottoms out by the end of this year, then the demand for bananas will increase by up to 8 percent next year.

FAO, however, is calling for more resources to go towards creating a global map of banana and plantain diseases. FAO noted that banana diseases could cost growers, particularly small-scale farmers, some USD 4 billion in 2010. Banana Bunchy Top Disease and Banana Bacterial Wilt threaten the food security of 70 million people in 15 countries in sub-Saharan Africa who depend on bananas for their livelihood and food supply. "[The diseases] merit far greater investment in public awareness, basic and applied research and farmer training and production services to growers," said FAO in the report.

Global food prices are on the rise again, with the FAO Food Price Index registering four straight monthly rises and hitting more than a year high in November, the United Nations Food and Agriculture Organization (FAO) said in its latest Food Outlook report. The UN organization however noted that the current market conditions are different from those that triggered the food price crisis that started two years ago.

FAO noted that the Price Index, which measures monthly price changes for a food basket composed of cereals, oilseeds, dairy, meat and sugar, averaged 168 points in November, the highest since September 2008. The index never exceeded 120 points and, for most of the time, was below 100 points during the 2007/08 food crisis.

"At the onset of the price surge in 2007, FAO identified a number of possible causes contributing to the price rise: low levels of world cereal stocks; crop failures in major exporting countries; rapidly growing demand for agricultural commodities for biofuels and rising oil prices," the FAO report said.

Bayer CropScience and the Philippines-based International Rice Research Institute (IRRI) announced that they will work together "to strengthen rice productivity through improved utilization of rice genetic diversity for crop improvement, disease management in rice, reducing greenhouse gas emissions, and capacity building for young rice scientists." Bayer and IRRI signed an agreement to establish a Scientific Know-how and Exchange Program (SKEP), which includes four joint activities.

First, the Germany-based crop science company will join an international effort that aims to develop an in-depth dataset of rice genome information for more than 2,000 different rice varieties and wild species. In addition, IRRI and Bayer will work together to develop tools to rapidly detect the dreaded bacterial blight disease of rice. The collaboration also includes the measurement of greenhouse gas emissions in rice fields following a switch from transplanted rice to direct-seeded and water-saving irrigation.

Bayer, early last year, joined the Hybrid Rice Development Consortium (HRDC), an IRRI-led partnership program between the public and private sector to develop and share hybrid rice technologies.

"This agreement will build on IRRI's capacity to deliver rice science solutions that help rice farmers increase their yields in an environmentally sustainable way and in so doing help lift farmers and consumers out of poverty", said IRRI Deputy Director General for Research Dr. Achim Dobermann.

Africa

Africa faces several constraints in harnessing the benefits of biotechnology - these include lack of adequate funds, loss of trained technical expertise, slow development of the biotechnology sector, inadequate intellectual property rights infrastructure, and government not taking a more active role in promoting the technology. Diran Makinde, director of the West African Biosciences Network (WABNet), Senegal, and colleagues forward these thoughts in Status of Biotechnology in Africa: Challenges and Opportunities published in the Biotechnology in Africa issue of the Asian Biotechnology and Development Review.

"Agricultural biotechnology alone will not solve the multitude of problems that farmers in Africa face; however, it has the potential to make crop breeding and crop management systems more efficient thereby generating improved crop varieties and higher yields," the authors wrote. To develop biotechnology in Africa they suggest the following: more coordination between strategic policy making in sustainable agriculture and agricultural research; political will and commitment to use the tools of biotechnology; regulatory frameworks that will work; and enhancement of public understanding and acceptance of products.

Biotechnology has been identified as one of the technologies that must be used for the  "rapid development" of  agriculture in Ghana. Marian Quain  and James Asibuo of the Crops Research Institute in Ghana, sub-Saharan Africa, discuss Ghana's initial foray into biotechnology and the challenges that the country is facing in Biotechnology for Agriculture Enhancement in Ghana published in the Biotechnology in Africa edition of Asian Biotechnology and Development Revew.

"One underexploited area in biotechnology in Ghana is the use of in vitro methods for the production of clean planting materials which are in high demand," the authors said. "This system needs the assistance of molecular tools to ensure that the clonal materials that is produced maintain their genetic integrity with the application of fingerprinting techniques."

The CRI scientists note the challenges of fund availability for the rapid development and adaptation of biotechnology tools; policy development, government contribution to science and technology, as well as regional collaboration to aid and promote the technology.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) said that it will deregulate Pioneer Hi-Bred's genetically modified corn event 98140 after "a thorough review of scientific information, public comments, and an environmental assessment." The GM corn, resistant to glyphosate and acetolactate synthase-inhibiting herbicides, can now be freely moved and planted without the requirement of permits or other regulatory oversight by APHIS.

APHIS said that scientific evidence indicates that any environmental, human health or food safety concerns associated with the GM corn line are "unlikely to occur."

Several farm and trade groups, including the American Farm Bureau Federation, the National Corn Growers Association and the American Seed Trade Association, have filed a joint friend-of-the-court brief to the US Supreme Court in support of a petition seeking review of case related to biotech alfalfa. "Lower courts failed to adequately consider the mountains of evidence that prove biotech alfalfa is safe, and thus those courts abandoned a well-established legal principle when they banned the planting of the crop," according to the brief. "If the courts do not respect those established legal standards, the ability to bring future innovations, especially biotech crops, to the marketplace is in real jeopardy." The brief further noted that the ruling "could begin a wave of anti-biotechnology injunctions."

Ascochyta blight, caused by the fungus Ascochyta rabiei, is one of the most devastating diseases of chickpea. The fungus attacks all above-ground parts of the host. During the winter, A. rabiei survives on chickpea stubble and forms sexual spores, called ascospores, which can infect plantings of the crop in the spring. Symptoms include necrotic spots in leaves, leading to severe defoliation, stems and pods. Severe outbreaks, fueled by cool, wet conditions, can wipe out the entire crop.

Now researchers from the U.S. Department of Agriculture's Agricultural Research Service (ARS) have identified another fungus that could be used to control A. rabiei. Frank Dugan and colleagues isolated Aureobasidium pullulans strains that inhibit A. rabiei's ability to form or release ascospores, thereby curbing its infection of chickpea seedlings. ARS noted that although there exist other ways to control the blight, such as treating chickpea seeds with fungicides, planting resistant varieties, plowing crop fields before planting time, and rotating chickpeas with non-host crops, biocontrol is worth exploring for its potential to provide chickpea growers with greater flexibility in how they manage the disease.

Field trials showed that treating chickpea stubbles with A. pullulans spores reduced Ascochyta blight by 38 percent. The ARS scientists expect that this can be improved using adjuvants and other standard ingredients often used in biocontrol formulations.

India's Union Minister of Science & Technology Prithviraj Chavan describes Bt brinjal a safe breakthrough in an exclusive interview in the latest issue of BiotechNews, an official news portal of the Department of Biotechnology (DBT), Govt of India. Speaking to the Biotech News, a bimonthly magazine of DBT, he says "I am sure that development of Bt brinjal, the first biotech vegetable crop, is appropriate and timely. I understand that it has been tested rigorously over the last nine years and has been found substantially equivalent to its non-Bt counterparts, except for an additional gene-cry1Ac which expresses Cry protein effective only against a very specific target insect, in this case Fruit and Shoot Borer (FSB). GEAC has evaluated Bt brinjal for its efficacy and safety as per the protocols and procedures prescribed under the Ministry of Environment and Forest's Environment Protection Act 1986 and Rules 1989 as well as DBT's own biosafety norms".

Addressing the concerns raised over the biosafety studies conducted for Bt brinjal, the Minister says "GEAC (MoEF) and Review Committee on Genetic Manipulation (RCGM) of DBT have jointly developed protocols for each test, closely monitored progress and ensured compliance during the testing of Bt brinjal. Bt brinjal has been tested extensively at various public sector institutions and nationally accredited laboratories with very good GLP track records in collaboration with Mahyco".  Bt brinjal, the first biotech vegetable crop which is grown by 1.4 million small and marginal farmers on 550,000 hectare in India, is declared safe for environmental release and recommended for commercial approval to the Ministry of Environment and Forest in mid Oct 2009. Highlighting the rigorous testing that has preceded the GEAC nod to Bt brinjal Mr. Chavan says "All these studies have concluded that Bt brinjal causes no adverse effects when consumed by humans, animals, non-target organisms and beneficial insects. In fact, Bt protein was not even detectable in cooked brinjal fruit".

Expressing his views on labelling regime for GM foods in India the Minister adds "It is advisable to adhere to labelling regime that is based on the nutritional composition of product and not on the process used to develop the product as long as the product has been determined as safe". Finally, lauding the role of Bt technology in agriculture, he says "The main advantage of this technology is that it reduces the use of chemical pest control making the technology safe for the environment as well as human consumption".

Recent advances in genomics research and plant biotechnology provide opportunities to facilitate the development of new sorghum cultivars and hybrids for high productivity of biomass with desirable cellulose. Yinghua Huang of the United States Department of Agriculture – Agricultural Research Service says that cellulosic biomass is becoming an attractive energy feedstock as the supplies are more abundant, and sorghum, in particular shows great potential due to its "high water-use efficiency, high biomass productivity under sustainable low-input conditions, and amenable to manipulation of its cell-well characteristics."

In a paper Molecular breeding of sorghum for use as a sustainable biofuel feedstock Yinghua sees the potential of genomic and biotechnological tools to enhance biomass productivity and manipulate cell wall structure and composition leading to an improved biomass quality. Furthermore, fundamental knowledge learned from sorghum (as a model) can rapidly be applied to other fuelstock candidates such as Miscanthus and switchgrass for their genetic improvement.

Bangladeshi Minister for Agriculture Begum Matia Choudhary stressed on the benefits of genetically modified crops at the 24th Foundation Day of the South Asia Association for Regional Cooperation (SAARC) on December 8, 2009. She said that research and development activities on GM will continue in full swing to get products to enhance crop production and alleviate chronic food crisis in Bangladesh. If GM crops are found superior in any aspect of crop cultivation, it will be released and made available to farmers, she said.

The Agricultural Minister reminded the audience that despite opposition to the technology, "we have been introducing hybrid crops since 1996 which are now benefiting our farmers. Similarly, government will not be conservative in the use of GM crops whatever resistance may come if any." She categorically directed scientists and the Institutes to strengthen research to develop disease, salinity and drought tolerant crops for farmers' use. Moreover, she told those who are criticizing GM crops to be moderate and be science-based. Minister Choudhary also declared that the government will formulate a Five Year Plan (FYP)  which will facilitate sustainable agricultural development.

"Challenges in Agriculture in SAARC Countries" was the main theme of the seminar organized by SAARC Agriculture Centre housed at Bangladesh Agricultural Research Council (BARC) campus in Dhaka under the chair of CQK Mostak Ahmed, Agriculture Secretary.

A focus group discussion on "The regulation of biotech-derived food products:current status and applications was held on 4 December at the Indonesian Ministry of Agriculture. Prof. Dr. Ir Dedi Fardiaz from Bogor Agricultural University pointed out that  "Risk analysis has become important to assess conditions and take decisions on control procedures. It is considered a prerequisite in the evaluation of genetically modified (GM) food. Many consumers worldwide worry that food derived from GMOs may be unhealthy and hence regulations on GMO authorizations and labelling have become more stringent."

Dr. James Maryanski, a Food and Ag Biotech Consultant and Former U.S. Food and Drug Authority Biotechnology Coordinator discussed "Codex Science-Based Approach to the Safety of Foods Derived from Modern Biotechnology". He noted that  "No adverse health effects have been found, including any from unintended changes. To date, there are no concerns that require long-term or multi-generation animal studies and after a decade of experience, all bioengineered foods on the market are as safe as conventional counterpart foods." The event  attended by 50 participants was organized by the Indonesia Biotechnology Information Cener (IndoBIC), IAARD, CropLife Indonesia, in collaboration with SEAMEO BIOTROP and PBP.

Europe

Researchers at the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME) in Germany have developed "super" potatoes that produce pure amylopectin through TILLING (Targeted Induced Local Lesions in Genomes). TILLING is an alternative to the traditional Agrobacterium-mediated transformation technique and uses mutagenesis coupled with gene-specific detection of single-nucleotide changes. Conventional starch is composed of the carbohydrate polymers amylose and amylopectin. Compared to amylose, amylopectin is more water soluble and with higher bonding capacity. Pure amylopectin starch is of high value in several technical applications such as paper, adhesive and textile manufacturing. But separating amylose from amylopectin is an energy and cost-intensive process.

According to the Fraunhofer researchers, 100 tons of these "super" potatoes were harvested earlier this fall. "They can be processed as usual in the production lines," noted Jost Muth, researcher at the IME . "Special measures aren't necessary, because the TILLING potatoes are totally normal breeds that contain no genetically modified material."

"Gene technology-based processes are indispensible and it is prudent to use them, when we want to integrate genetic material into a plant genome, for example if we develop transgenic tobacco plants producing pharmacological substances," said IME scientist Dirk Prüfer. "When it comes to dealing with genes, there is an easy rule: as much modification as needed, but as little as possible."

Research

Carbon monoxide (CO) has been shown to regulate some biological processes in animals such as vasomotion, respiratory regulation and thermoregulation. It has also been implicated as a messenger molecule involved in intercellular neuronal communications. CO shares some biological properties of nitric oxide (NO), which has been shown to regulate a wide array of plant physiological responses including regulation of nutrient metabolism. The roles played by CO in nutrient stress responses in plants, however, remain largely unknown. Now, researchers at the Nanjing Agricultural University in China showed that CO can regulate iron-homeostasis in iron-starved Arabidopsis.

The researchers found that exogenous application of CO prevented chlorosis in iron-deficient Arabidopsis and Chlamydomonas. Endogenous level of CO was increased in Arabidopsis under iron deficiency. The compound was also found to regulate the expression of genes related to iron acquisition, specifically IRT1, FRO2, FIT1 and FER1. FRO2 and FER1 respectively codes for ferric reductase, which is required for plant acquisition of iron at low level in soils, and ferritin, a protein that stores iron.

CO treatment of maize mutants with defective iron intake resulted to restoration of greening in leaves. In addition, the team found evidences suggesting cross-talks between CO and NO in low iron conditions.

Researchers at the National Taiwan University have developed tobacco plants with dual resistance to the bacterial soft rot disease caused by Erwinia carotovora and damping-off disease caused by Pythium aphanidermatum. The plants also showed increased resistance against the Helicoverpa armigera larvae.

The tobacco plants express stacked genes that code for sporamin and CeCPI, protease inhibitors from sweet potato and taro, driven by the wound and pathogen responsive pMSPOA promoter. The researchers observed that the tobacco lines showed limited stomata penetration by zoospores, poor germination, and hyphal elongation.

"Our results suggest that stacking protease-inhibitor genes is an effective strategy for engineering crops with resistance against insects and pathogens,"  the researchers wrote in a paper published by the Plant Biotechnology Journal. Plant protease inhibitors are thought to play an important role in defense against insect and pathogen attack.

Researchers from the University of Georgia, looking at how the isochorismate synthase (ICS) gene is regulated in Arabidopsis and Populus, found for the first time an inverse relationship between gene duplication and alternative splicing in plants. Led by Chung-Jui Tsai, the team believes that the discovery has implications for diversity not only in plants, but in animals and humans.

ICS encodes an enzyme that plays important roles in the synthesis of vitamin K for photosynthesis and synthesis of salicylic acid for stress response. Arabidopsis has two copies of the ICS gene. Populus, on the other hand, only has one. Tsai and colleagues discovered that Populus ICS undergoes extensive alternative splicing which is rare for the duplicated ICS and that it does not respond to stresses. Alternative splicing allows genes to produce two or more protein products with potentially different functions.

When the Populus ICS gene was inserted into an Arabidopsis mutant that lacked the stress-fighting ICS copy, the team found that the introduced gene could not be correctly spliced at all in the foreign Arabidopsis host and could not restore the plant's ability to produce salicylic acid. Tsai's team proved that unlike in Arabidopsis, Populus ICS functions primarily for photosynthesis. Populus, and other trees, which face environmental stress throughout their long lifetimes have evolved other pathways to synthesize salicylic acid and other chemicals for "constitutive" defense, Tsai pointed out.

"The finding that the Populus ICS gene cannot be properly spliced in Arabidopsis opens up new prospects in the quest for what makes a tree a tree," said Tsai. "The quest is certainly beyond differences in gene numbers, or individual gene functions, between trees and weeds."Tsai said she suspects that "subtle but fundamental differences in how genes are spliced between these species can have significant contributions as well."
