The International Rice Research Institute (IRRI) added 42,627 seed samples of various types of rice in its collection kept in the Scalbard Global Seed Vault, informally called as "Doomsday Vault" because it houses "all of the world's important crop seeds that may be humanity's ultimate insurance in food security in the event of a major regional or global crisis." The conditions inside the vault would enable storage of the seeds for hundreds of years. The vault was inaugurated in February 2008 and IRRI first deposited 70,180 rice samples.

"IRRI shares seed from the IRG for free with farmers, farmers' groups, governments, universities, and others under conditions set by the International Treaty on Plant Genetics Resources for Food and Agriculture," said Dr. Ruaraidh Sackville Hamilton, head of IRRI's International Rice Genebank (IRG). "One hundred twenty-six countries signed this Treaty that ensures the fair sharing of benefits from the use of these resources."

Africa

Researchers at Namulonge in Uganda are working on the biofortification of cassava by developing new varieties with high levels of beta carotene, which converts into vitamin A upon consumption. These new varieties are also resistant to cassava mosaic disease.

"We have over 20 clones that have different colors beginning from light yellow to pink or deep orange cassava. The intensity of color reflects the quantity of carotene," says Dr. Robert Kawuki, a cassava breeder at Namulonge.

The yellow cassava varieties used for breeding were from Latin America, where the crop originated. The research started three years ago and is expected to finish after another three years. It is a long-time process because of the rigorous evaluation and selection stages being conducted. The project hopes to produce  varieties that would most-likely be adopted by the farmers, and decrease the prevalent health problem of vitamin A deficiency in Uganda. The research is under the National Cassava Research Programme.

Public awareness and acceptance on agricultural biotechnology continuous to improve as products of agricultural biotechnology and biotech regulatory policies move forward in Africa. This was shared by Dr. Margaret Karembu, Director of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) AfriCenter, in a Special Seminar held at the SEAMEO Regional Center for Graduate Study and Research in Agriculture (SEARCA), Los Baños, Philippines last October 27, 2010. African farmers appreciate agricultural biotechnology products, and are ready to be involved when they are introduced to something that could improve their lives, said Dr. Karembu.

Africa has initiated "harmonization" of their biosafety policies through the Regional Economic Communities (REC) exemplified by forming the Regional Approach to Biotechnology and Biosafety Policies in Eastern and Southern Africa (RABESA), which covers 19 member states. The RABESA has helped tailor fit biosafety policies to the different countries based on identified priority areas which are the commercial planting, commercial trade policy, and emergency food aid access to GM crops and GM produces. Dr. Karembu reported that at present, 12 countries in Africa have already developed National Biosafety Frameworks (NBFs), while 11 have interim NBFs.

According to Dr. Karembu, the factors that would determine the future of biotechnology in Africa include: a proactive policy where priorities are identified and decisions are suited for Africa's needs; an efficient and cost effective biosafety system that would effectively assess biotechnologies; scientific capacity buildings; an IPR regime to encourage private small seeds companies to invest in the technology; and public awareness and acceptance initiatives that build on credible and evidence-based communication.

Researchers at Kansas State University were awarded a patent for their invention entitled Compositions and Methods for Controlling Plant Parasitic Nematodes. The team developed a transgenic strategy to fight off the destructive soybean cyst nematode which can cause up to US$860 million losses annually.

By targeting three genes, namely MSP, or Major Sperm Protein, which causes nematode sperm to move; Chitin synthase, the gene that helps form the eggshell on nematode offspring; and RNA Polymerase II, which is vital for RNA production, the researchers were able to reduce nematode reproduction by 68 to 70 percent. The team also made sure that the altered genes could not affect the soybeans and non target organisms such as animals and humans.

"We've engineered a new metabolic pathway in plants for producing a kind of fatty acid that could be used as a source of precursors to chemical building blocks for making plastics such as polyethylene," said Brookhaven biochemist John Shanklin of the U.S. Department of Energy in collaboration with Dow AgroSciences.

The report published in the online edition of Plant Physiology describes how in many series of metabolic pathway experiments and search of a model gene receiving plant, the scientists were able to produce the desired omega-7 fatty acid at 71 percent level in the best expressing Arabidopsis line. In summary, the researchers "down-regulated" genes that compete for the introduced enzyme's fatty acid substrate and also introduced desaturases capable of intercepting substrate that had escaped the first desaturase enzyme as it progressed through the oil-accumulation pathway, the news article said.

Dr. Jennifer Thompson, Emeritus Professor at the University of Cape Town (UCT), South Africa, shared the status and development of agricultural biotechnology in South and sub-Saharan Africa in a seminar held last October 27, 2010 at SEARCA, Los Baños, Laguna, Philippines. Drought tolerant maize, virus resistant maize, insect resistant potato, and nutritionally enhanced sorghum are crops currently being improved through genetic modification in South Africa. Prof. Thompson is hopeful that these crops would be commercialized in the future.

Prof. Thompson's team at UCT is working on drought tolerant maize, to be tested with genes from a "resurrection plant" which can survive months in a dehydrated state and come back to life in 72 hours once exposed to water. Another project addressing drought tolerance for maize is the Water Efficient Maize for Africa or WEMA. The WEMA is a public-private partnership project that aims to bring royalty-free drought tolerant maize varieties to farmers of sub-Saharan Africa.

In addition, Prof. Thompson and her team are also developing maize resistant to the maize streak virus (MSV) using replicase genes. She reported that MSV is endemic to Africa, and has caused huge economic losses to both commercial and small scale farmers. Development of the virus-resistant maize will be beneficial to the entire African region.

Research

Developing drought tolerant Egyptian cotton varieties is necessary to expand the hectarage amidst shortage of water in the Nile valley. One of the strategies to produce plants with multi-stress tolerance is by overexpression of S-adenosyl methionine decarboxylase (SAMDC) gene which codes for the biosynthesis of polyamines, an organic polycation that triggers plant growth and development to adaptation toward abiotic stress. This strategy was used by Osama Momtaz of the Agriculture Research Center, Giza and colleagues in their work. SAMDC gene was isolated from yeast (Saccharomyces cerevisiae) and then genetically engineered into Egyptian cotton varieties Giza 88 and Giza 90 through particle bombardment.

The transgenic plants were subjected to different levels of drought and the accumulation of spermine, a type of polyamine, was detected and compared with the controls. To confirm gene expression in the transgenic plants, they used RT-PCR analysis which amplified the DNA. Then the gene integration was confirmed through Southern blot analysis. Results showed that there are high levels of spermine in the transgenic varieties, which is the main contributor in increasing the plants' tolerance to drought.

Genetic engineering for the expression of Bt toxins in crops is one of the prevalent and reliable ways to control pests. However, previous studies have shown that insects tend to adopt to the Bt toxin. Thus, scientist Bruce Tabashnik of the University of Arizona and colleagues tested a novel approach to address this problem. They released sterile insects released to mate with Bt-resistant larvae. According to computer simulations, it was proven that this approach works in principle against pest with recessive or dominant inheritance of resistance. This was done for four years at large-scale field deployment in Arizona. During that period, the resistance of pink boll worm to Bt cotton did not intensify. This reduced the abundance of pink boll worm by >99 percent, as well as the rampant spraying of insecticide against the pest.

Future climates are expected to expose rice to high temperature and water stress during crucial stages of development such as flowering. Z.W. Rang of Hunan Agricultural University, China, together with other scientists conducted a study to measure the effect of high temperature and water stress on rice spikelet fertility. They exposed five rice genotypes to high temperature, water stress, and combined high temperature and water stress during flowering.

Through microscopic analyses, it was revealed that there were significant variations in the time of anther opening during maturity between treatments and genotypes, with moderately high association with the number of germinated pollen grains on the stigma.

All the treatments resulted to spikelet sterility, with the high temperature treatment causing highest sterility. It was also observed that spikelet fertility declines as the temperature increases. Among the five genotypes, N22, an Aus rice cultivar is a good high temperature and water deficit stress tolerant donor.
