Crop bioengineering opens the floodgates to opportunities for crop improvement. However its success depends to a large extent on how effectively the global scientific community and the public and the private sectors can harness together its power and other allied fields of genomics and bioinformatics for the world's poor. In Crop bioengineering: Enormous potential for catalyzing international development published in Agriculture for Development, Peter Gregory of Cornell University and Stanley Kowalski of the Franklin Pierce Law Center, USA, say that: "This in turn depends on the extent to which projects are demand-driven and holistic in approach, integrating all technical and non-technical factors relevant to the product development and commercialization/delivery chain."  Strong emphasis must be placed on inter-institutional collaboration and focused and sustained capacity building at both human and institutional levels.

Successful distribution of bioengineered crops requires a communication strategy that provides regular and accurate information about them to various stakeholders. Gregory and Kowalski conclude that this will facilitate public acceptance and continued development of bioengineered crops.

Interim director of Purdue's Climate Change Research Center Noah Diffenbaugh, co-author of a Purdue study, said that  "Studies have shown global warming will likely increase the frequency and intensity of heat waves, drought and floods in many areas. It is important to understand which socioeconomic groups and countries could see changes in poverty rates in order to make informed policy decisions." With this as a guide, the team used data from the late 20th century and projections for the late 21st century to develop a framework that examined extreme climate events, comparable effects to grain production and the impact on the number of impoverished people in the 16 developing countries studied.

"Bangladesh, Mexico and Zambia showed the greatest percentage of the population entering poverty in the wake of extreme drought, with an additional 1.4 percent, 1.8 percent and 4.6 percent of their populations being impoverished by future climate extremes, respectively," Thomas Hertel, a co-author of the study said. There will also be large reductions in grains productivity due to extreme climatic events.

This study is an initial quantification of how poverty is tied to climatic fluctuations, and the team is improving the modeling and analysis system to enable more comprehensive assessments of the link between climate volatility and poverty vulnerability.

A virulent strain of the wheat rust disease is on a global march, leaving a trail of destruction in its wake. Originating in Uganda (hence the name UG99) and having made its way to the Arabic Peninsula, the disease caused by the fungus Puccinia graminis now threatens the wheat mega-producing countries of Central Asia. A new partnership has been formed that aims to develop wheat varieties that can better resist the dreaded fungus. Syngenta AG, the Syngenta Foundation for Sustainable Agriculture (SFSA) and the International Maize and Wheat Improvement Center (CIMMYT) will work together to identify and map genetic markers for use in wheat resistance breeding. The marker data arising from the research will be made available to the public.

SFSA said in a press release that the research collaboration will "combine Syngenta's plant genetic profiling expertise with the strengths of CIMMYT's extensive field research to develop a genetic map of wheat stem rust resistance." SFSA will be funding the project.

CIMMYT Director General Thomas Lumpkin noted that the Center is "very pleased to enter the new partnership." Lumpkin said, wheat yields need to rise 1.6 percent each year to reach required global production levels by 2020, yet investments in wheat technology have lagged far behind those for other cereals.

Africa

In the 2nd World Congress of Agroforestry, Director General Dennis Garrity of ICRAF (World Agroforestry Centre), host of the Congress said that, "Growing the right tree in the right place on farms in sub-Saharan Africa-and worldwide- has the potential to slow climate change, feed more people, and protect the environment. This tree, as a source of free, organic nitrogen, is an example of that. There are many other examples of solutions to African farming that exist here already."

The tree he is referring to is the tall, long-lived acacia tree Faidherbia albida, known for its nitrogen-fixing qualities that could limit the use of fertilizers; provide fodder for livestock, wood for construction and fuel, and medicine through its bark as well as windbreaks and erosion control to farmers across the sub-Saharan Africa. The tree is also widely adapted to a wide array of climates and soils from the deserts to the humid tropics. 

With African farms being severely degraded and African farmers applying only 10 percent of soil nutrients used in the rest of the world, planting acacia tree is an important option. The tree goes dormant and shed its nitrogen-rich leaves during the early rainy that coincides with the planting season. Field crops planted around the trees are fertilized during their entire growing season, and leaves and pods provide fodder for livestock in the dry season  when the plants have dried up. In many African countries, the tree is a frequent component of farming systems.

Yield increases have been documented in unfertilized millets grown under the tree in West Africa, for sorghum in Ethiopia, other parts of Africa, and in India, in addition to groundnuts and cotton. Often, millet and sorghum exhibit no further response to artificial fertilizers beyond that provided by the tree's leaf fall.

Through a $10.2 million loan from the International Fund for Agricultural Development, a program was introduced to distribute and multiply quality seeds of such crops as beans, maize, and sorghum and planting materials for cassava, sweet potato and banana to farmers in Haiti. In addition, 500 tonnes of rice seed will also be distributed.

According to the Food and Agriculture Organization which is implementing the project, the scheme has significantly increased food production, provided cheaper food, and boosted farmers' incomes. Almost 250,000 smallholder and landless farmers are expected to benefit from the program. "We are extremely encouraged by the results we are seeing in this program which, along with favorable weather, has been an important factor in increasing the amount of food available to poor people in Haiti," said FAO Haiti Representative Ari Toubo Ibrahim.

The newly-bred "CRIL-7" chickpea is hoped to end the fight against the crop-damaging larval stage of the beet armyworm, said a report by the United States Department of Agriculture-Agricultural Research Service. Chickpea provides protein, fiber and other nutrients, and an important crop in semi-arid tropical countries like India. The beet armyworm is a very devastating pest in India which used to be the world leader in chickpea production in 2005.

The team of scientists led by entomologist Stephen Clement selected 42 lines from the seven generation of progenies from the cross between the wild species Cicer reticulatum which has broad insect resistance trait, with the susceptible cultivar FLIP 84-92C. The selected lines were tested in 2006-07 green house trials, and 28 to 62% of the beet armyworms that fed on the leaves died within a few days from hatching from eggs. Worms which survived were shorter and smaller. Agronomic testing will be conducted next before the lines are commercialized.

The Agricultural Plant Biotechnology Association (Agro-Bio) and the Institute of Biotechnology, National University (IBUN) in Colombia organized a field trip for journalists to visit farmers' fields planted to genetically modified maize in Meta, Colombia. Meta is located east of the Andes mountains. The journalists were able to interact with Sergio Valencia, a farmer who had 20 years experience in planting different crops but was growing GM maize for the first time.

Agro-Bio reports that the journalists were able to appreciate the technology through their interaction with those who are directly benefiting from it. Biotech maize is not approved for commercialization in Colombia. However, in 2008, it planted biotech maize in a "controlled planting program". In May 2009, the Colombian Agricultural Institute approved the semi-commercial planting of Bt-11 maize.

Scientists of the United States Department of Agriculture-Agricultural Research Service headed by geneticist Jay Evans found that the presence of abnormal ribosomal RNA (rRNA) fragments in the guts of honey bees may be the cause of Colony Collapse Disorder (CCD). This disease caused the decline of the honey bee population last year.

Using genome-wide microarray, the scientists found a large amount of abnormal rRNA fragments which indicate that the affected honey bees had reduced ability to synthesize new proteins. According to entomologist Mary Berenbaum, if the bees' ribosomes are compromised, then they can't overcome exposure to pesticides, viral, fungal, bacterial infections or inadequate nutrition because the ribosome is central to the survival of any organism. 

Although the study did not establish a direct cause-and-effect link between the abnormal rRNA and CCD, colony surveillance by assays of rRNA and other markers expressed by bees could provide the earliest indication of CCD found so far.

An industry-led group, called the Global Harvest Initiative, announced the launch of a campaign that aims to "heighten awareness of the increasing gap between the world's agricultural production capacity and what will be required to meet the needs of a growing population." Global Harvest Initiative was founded by four U.S. agricultural companies: John Deere, DuPont, Monsanto and Archer Daniels Midland Company. The group will launch the effort in a symposium in Washington DC in the U.S. next month.

"The Global Harvest Initiative is mobilizing a diverse group of thought-leaders to focus on the challenge of doubling agricultural output, and doing so in a sustainable manner," said William G. Lesher, executive director of the Global Harvest Initiative. "Already, efforts are underway to enhance agricultural production, minimize post-harvest losses and introduce efficiencies throughout the value chain. But achieving such a monumental task requires additional attention and support from many."

In a press release, Mycogen Seeds announces 14 new elite MYCOGEN SmartStax hybrids, including 12 grain corn hybrids and two MYCOGEN brand SILAGE-SPECIFIC™ corn hybrids. The hybrids contain the broadest spectrum insect control to date, and would provide growers a yield advantage due to reduced refuge requirement: 5 percent refuge instead of the traditional 20%.

In addition, they have all season built-in protection from both above- and below-ground corn pests, including earworm, fall armyworm, western bean cutworm and rootworm. The multiple modes of action brought by the different insect resistance genes attack pests at two locations in the midgut, making it much more difficult for insects to develop resistance to the technology.

"Growers can maximize profits by planting MYCOGEN SmartStax hybrids. Our lineup offers a wide selection, so growers can find the right hybrids for their unique on-farm situations," says Keith Porter, agronomy services manager, Mycogen Seeds.

For the detailed listing of the hybrids and their specific traits, see the press release at http://www.dowagro.com/mycogen/resource/newsreleases/20090826a.htm

Genetically modified (GM) rice may soon be part of a Chinese meal. "China has worked on research of transgenic rice and is strongly considering its commercialization," says Vice Minister of Agriculture Niu Dun. This was concurred by Cao Mengliang, a researcher on molecular rice at the China National Hybrid Rice R&D Centre, who added that: "Studies of the safety of the technology have been completed. Discussions about whether to open it up to the market are now in the final stages. Now, the safety certificate is the last thing needed before commercialized production."

China Daily reports that the Center for Chinese Agricultural Policy notes that GM rice could lead to an 80 percent cut in pesticide use and that yields could increase by around 6 percent. China currently produces around 500 million tons of rice. With its population expected to grow to 1.6 billion by 2020, 630 million tons of rice will be needed.

Europe

At the Max Planck Institute for Developmental Biology in Tubingen, developmental biologists have discovered that the regulatory mechanism that switches Arabidopsis to flower depends on a group of related regulators, the SPL proteins. Its production on the other hand is triggered with the decrease in concentration of microRNA in the shoot apex of flowering plants. This activation process occurs even in the absence of other regulators that measure daylength or external temperature, which may allow a sufficiently old plant to flower even in an unfavorable environment.

MicroRNAs are very short RNA sequences that function as essential regulators in the proper functioning of genes in plants and animals. By binding to the complementary motifs in a messenger RNA (coding for amino acids), they inhibit its translation to protein and the consequent inactivity of the corresponding gene. As the microRNA concentration is lowered, plants can synthesize the corresponding proteins needed for flowering.

A field of genetically modified (GM) barley was destroyed by activists last week in Gunnarsholt, Southern Iceland, according to a report by Iceland Review. The field was the property of ORF Genetics, a start-up company that produces pharmaceuticals and medical research products from GM plants. Björn Lárus Örvar, ORF's CEO, told Iceland Review that the activists have caused the company millions in damage. "For a small company like ours, which is struggling in the difficult innovation environment, this is a serious matter." Responsibility for the attack has been claimed by a group of activists which calls itself Illgresi (weed in Icelandic).

Attacks on GM field trials have been common in Europe, particularly in Germany, France and the United Kingdom. Recently, environmental activists ripped up a field of nematode-resistant GM potatoes in Yorkshire, UK. The destruction caused more than USD 40,000 damage and wasted months of research.

The European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI), based at Hinxton near Cambridge, has received a £10 million (USD14.3 million) grant from the UK's Biotechnology and Biological Sciences Research Council to dramatically increase EBI's data storage and handling capacity. The BBSRC funding is expected to help fuel the success of ELIXIR, a large-scale, EU-funded, data-storage project. The grant adds to the USD 6.3 million that the European Commission awarded to launch the project a year ago and an additional USD 2.5 million that several Swedish funding agencies pledged towards the project earlier this year.

Huge amounts of biological data are being generated daily throughout Europe. In order to use the data efficiently and to accelerate advances, such as the development of new drugs or higher yielding crops, scientists require better ways to deal with the flood of information.

"The UK's decision to invest in ELIXIR is an important milestone in creating the infrastructure for biological information in Europe," said Janet Thornton, EMBL-EBI Director and ELIXIR coordinator. "The EBI will form the hub of a network of ELIXIR nodes that will empower European science at the interface of biology, computing and data management - one of the most vibrant areas of contemporary research."

Research

Scientists from Japan have pinpointed a gene that helps rice plants resist the dreaded blast disease. Having this gene in high yielding but disease susceptible varieties could help feed millions more people.

A Global Problem

Rice is life for more than half of the world's population. It is the second most widely grown cereal in the world, next to wheat. The crop was planted in more than 155 million hectares in 2008. Around 2.5 billion people in Asia, mostly from developing countries such as India, China, Indonesia and Bangladesh, obtain more than 70 percent of their caloric intake from rice and its derived products. In addition, more than a billion households in Asia, Africa and America, depend on rice for their main source of livelihood.

The global rice production, however, is faced with numerous challenges. According to the United Nations Food and Agriculture Organization (FAO), diseases, insects and weeds are responsible for yield losses of up to 30 percent. The blast disease is one of the most serious and widespread diseases of rice. Caused by the fungus Magnaporthe oryzae, the disease is capable of wiping out entire rice fields. Most rice cultivars are susceptible to the rice blast.

In Japan, as much as 200,000 tons are lost annually to the disease, according to Dr. Shuichi Fukuoka, a scientist at the country's National Institute of Agrobiological Sciences.

A Moving Target

Magnaporthe oryzae is no easy target. Numerous researchers have identified genes that provide resistance against blast. But the pathogen can easily evolve resistance against these genes. What's more, rice cultivars equipped with these genes are usually inferior in terms of agronomic performance.

Recently, a team of Japanese researchers led by Shuichi Fukuoka identified a novel gene that promises longer lasting resistance against the blast-causing fungus. The gene, pi21, encodes a proline-rich protein with putative heavy metal-binding domain and putative protein-protein interaction motifs. It was traced to a Quantitative Trait Locus (QTL) in a blast resistant rice cultivar that has long been grown in Japan. The cultivar, however, is unpopular because it produces lower quality rice.

Researchers from the University of Virginia in the U.S. have successfully identified a gene in cowpea that confers resistance to the parasitic weed Striga. Also known as witchweed, Striga infests some 50 million hectares of cereal crops and is responsible for more than USD 7 billion worth of crop damage every year in Africa. Underground witchweed parts connect to crop roots and feed on them, reducing yield dramatically and sometimes even destroying entire fields. Striga attacks numerous crops, including cowpea, a major food and forage legume in the Sahel of West and Central Africa. Controlling the parasitic weed through conventional techniques is a challenge. Striga is known to produce thousands of seeds that can stay dormant in the soil for years.

The Striga resistance gene, RSG3-301, encodes a protein localized in the peripheral plasma membrane that serves as a guard molecule against Striga attachment and penetration. Silencing this gene in resistant varieties resulted to susceptibility to Striga attacks. Cowpea plants incapable of expressing RSG3-301 "failed to mount a resistance response when challenged with a particular Striga race and allowed the weed to penetrate the endodermis and to establish xylem-xylem connections with the host vascular system," the scientists wrote in a paper published by Science.

There are at least seven Striga races, each with the capability of adapting to different cowpea varieties. The researchers are now trying to develop cowpea plants that are resistant "across the board."

Numerous studies have shown that diets rich in omega-3 fatty acids decrease the risk of cardiovascular diseases. Dietary ingestion of these fatty acids has also been shown to reduce the symptoms of metabolic syndrome or syndrome X. The main dietary source of omega-3 fatty acids, particularly eicosapentaenoic acid and docosahexaenoic acid, is oily fish such as sardines, mackerel and salmon.

A team of researchers from the Rothamsted Research and University of York in the UK developed transgenic Arabidopsis and linseed plants accumulating significant amount of the omega-3 fatty acid stearidonic acid in their seed lipids. The transgenic plants express the gene that codes for Δ6-desaturase, the key enzyme in stearidonic acid biosynthetic pathway, from primrose (Primula vialii). The researchers reported that in the case of the transgenic linseed plants, "the achieved levels of stearidonic acid (13.4% of triacylglycerols) are very similar to those found in the sole natural commercial plant source (Echium spp.) or transgenic soybean oil."

The stearidonic acid-enriched linseed oil may have superior health-beneficial properties, the researchers said. Unlike Echium and transgenic soybean derived oils, it lacks γ-linolenic acid, which is considered undesirable for heart-healthy applications. It also has a significantly higher omega-3/omega-6 ratio.
