The Open Forum for Agricultural Biotechnology in Africa (OFAB) is celebrating its fifth anniversary with a US$3 million grant from the Bill and Melinda Gates Foundation. The grant, announced during OFAB's anniversary celebrations in Accra, Ghana, seeks to enhance knowledge sharing and biotechnology awareness and build an enabling environment for decision making for agricultural biotechnology in Africa.
During the anniversary celebration, Hon. Sherry Ayittey, Ghana's Minister for Environment, Science and Technology said that "Biotechnology has delivered substantial benefits to farmers around the world but Africa still lags behind in exploiting its potential partly due to lack of an enabling environment for the development and use of agricultural biotechnology."
Five African countries, namely, Ghana, Kenya, Nigeria, Tanzania, and Uganda, currently implement OFAB in collaboration with a number of partners. Monthly meetings are held in different countries, where topics on agricultural biotechnology are presented and discussed. Specific areas of discussion include understanding agricultural biotechnology and how it applies to Sub-Saharan Africa, updating stakeholders on biotechnology project developments and discussing enabling factors such as intellectual property management, liability, seed systems and commercialization.
More information, including the news release about this event is available at OFAB's website at http://www.ofabafrica.org/news_article.php?id=82.
The first Biotechnology Day organized by the Faculty of Agriculture, Cairo University and the Egyptian Biotechnology Information Center (EBIC) celebrated the 10th anniversary of the biotechnology program on April 7, 2012. This outreach effort was designed to acquaint new students with the biotechnology program and career opportunities in the biotechnology industry.
The Faculty of Agriculture at Cairo University identified the importance of biotechnology as an area with tremendous growth potential. In 2002, the program was first opened as the first biotechnology program in Egypt and the region.
A highlight on the Global Status of Commercialized GM Crops was presented indicating the importance of cultivating these crops and how that could help to alleviate world hunger.The role of scientists to disseminate the correct information about biotech crops and their benefit to small farmers, and agricultural development was demonstrated.
The students took the initiative to clarify what biotech crops are and presented a play called GM Crops vs Consumers where they talked about transgenic maize, cotton, soy bean and potato. They also applied easy to understand biotechnology techniques through a play called Houdini (Famous Magician) and Biotech. They showed the audience how to simply isolate DNA from saliva by using very simple materials that could be found in any kitchen. They also acted out in a short play about the struggle between the devil and angel concerning the ethics of using GM crops.

The Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) believes that utilizing benefits of agricultural biotechnology can help sub-Saharan Africa countries to attain food security. "Genetically Modified Organisms (GMO's) provide the best solution to food insecurity and a gateway to a modernized agriculture," said Dr. Charles Mugoya, head of agro-biodiversity and biotechnology at ASARECA while speaking during the Uganda launch of the Global Status of Commercialized Biotech/GM 2011.
Ugandan farmers were also urged to be receptive to biotech as the crops will eventually be commercialized in the country. While speaking at the same forum, the president of Uganda National Farmers' Federation (UNFFE) Charles Ogang urged farmers to take up biotechnology and science based approaches as an avenue to feed the ever increasing population. "Biotechnology is no longer a western thing and research has shown that biotech has even been used to develop vital drugs against diseases like diabetes and measles among others," Ogang noted.

Considerations in Gender-Responsive Priorities for Effective Agri-biotech Dev't in Sub-Saharan Africa
Addressing gender issues is an important aspect in the development of agri-biotech systems in sub-Saharan Africa. Obidimma Ezezika and colleagues at Sandra Rotman Centre in Canada conducted interviews with key stakeholders in agri-biotech across sub-Saharan Africa. With the results of the interview, together with review of available literature and field observation, the team found that incorporating a gendered perspective is critical for sustainable development of agri-biotech. It is critical that women must be considered and participate equally with men in various aspects such as decision-making on trait selection of biotech crop; education for agri-biotech research; and control over biotech crop management and income generation.

Researchers in Argentina have isolated a drought resistance gene from sunflower and spliced it into soybean, aiming to improve yields of the biggest cash crop in the country. Raquel Chan and her team have identified the HAHB4 gene that makes sunflowers resistant to dry conditions and implanted it in rockress flowering plants whose resistance to drought increased. An agreement with Argentina's Bioceres will allow Chan's team to exploit the gene as Bioceres has conducted previous tests on soybean, wheat, and corn.
When HAHB4 is inserted into soybean, wheat or corn, yields increased between 10 to 100 percent, depending on crop quality and local conditions. "The tougher the environment, the more advantageous the transgenic plant," said Chan, who heads the Agrobiotechnology Institute at the National University of the Coast.
The Argentinian government hopes to license the seeds by 2015, as supporters see a boost in soybean productivity in the country, particularly after a severe drought cut Argentina's soybean production by more than 30 percent.

Purdue University scientists reported that the current hybrid corn varieties are more nitrogen-efficient than the old varieties. This finding is based on 72 years of public sector research data which was reviewed by the scientists.
Doctoral student Ignacio Ciampitti and team discovered that yield of corn continued to increase even if there were less spaces between the plants. The plants sustained enough nitrogen even under higher plant densities.
"We are getting clues on how plants have already improved nitrogen use efficiency, and we will use that to push for further increases," Ciampitti said. "We finally feel like we're shedding some light on what traits plant breeders should select for to increase nitrogen efficiency even more."
The next goal of the researchers is to know how water use efficiency and nitrogen use efficiency can be combined to develop corn with better tolerance to environmental stresses.
Texas AgriLife Research scientists led by geneticist Shuyu Liu are working on a study that will identify the key genetic regulators for wheat's drought tolerance mechanism. Liu's team will use a set of physiological and molecular tools to discover the mechanisms of drought adaptation and will focus on three widely planted wheat varieties in the US High Plains namely, TAM 111, TAM 112, and TAM 304.
The AgriLife scientists' observations and the physiological traits they have collected show that these three cultivars respond well to water stress. TAM 111 is good at both irrigated and dryland, TAM 112 is better in prolonged dry conditions, and TAM 304 performs well if irrigated. The wheat was planted in November last year and includes two drought-tolerant varieties and one drought-susceptible variety. The experiment is now at harvesting stage and Liu and his team has collected samples from different plant growth stages for laboratory analysis.

The American Farm Bureau Federation (AFBF) encouraged the Agriculture Department's Animal and Plant Health Inspection Service (APHIS) to grant non-regulated status to a new variety of herbicide-tolerant corn. According to AFBF, the approval of the DAS-40278-9, the regulatory name of the genetically engineered (GE) corn variety, will offer farmers an alternative to eliminate persistent weeds and respond to potential herbicide resistance.
AFBF also mentioned in their letter to Department of Agriculture Secretary Tom Vilsack that APHIS has done an excellent job in completing comprehensive plant and environmental assessments that show DAS-40278-9 as "unlikely to pose a plant pest risk".
This new corn variety is tolerant to the herbicide 2,4-D which has been used in the U.S. for 60 years to control weeds in crops. AFBF notes that in order to maintain the country's international competitiveness and also to achieve productivity that would meet the needs of the 21st century, the agricultural sector of the U.S. must remain on the cutting edge of technology.

In a study by Matthew Greenstone at the Agricultural Research Service in Beltsville, Maryland, DNA barcodes was used to identify effective insect predators to control the Colorado potato beetle. The insect is the most damaging insect pest of potatoes in the Eastern United States. Its control using predatory insects has been explored earlier, the present study allowed the identification of the specific predator using barcodes, by following the time required for different insects to digest their prey. Scientists sequence part of an organism's genome and produce a barcode from it.
The paper published in Entomologia Experimentalis et Applicata reported how the four potato beetle predators which were collected and fed with lab-raised potato beetles were studied to determine how long the pest's barcoded DNA could be detected in the predator's guts. The results find application in possibly guiding growers on the most effective strategies for controlling the pest. Worldwide efforts in DNA barcoding of plants and animals are currently underway to catalogue the diversity of life on Earth.

Vietnam targets to promote the use of advanced agricultural technologies and develop more high agricultural zones toward 2020. To this end, Ministry of Agriculture and Rural Development Deputy Minister Bui Ba Bong will set to finalize and submit a plan for high tech agricultural zones to the Vietnam government for approval in June. Some biotech projects are already being implemented in Ho Chi Minh City and some others in Hanoi, Lam Dong, Phu Yen, and Nghe An.
"However, although there is already an existing policy or Law on High Technology for the promotion in these industries, detailed guidelines are still lacking," Deputy Head of the Ministry of Science, Technology and Environment Nguyen Tan Hinh said. Deputy Minister Bong added that "hi-tech agriculture is a complicated industry and hasty, massive development should be avoided." Hopefully, the upcoming plan that also includes the missing guideline will help increase the application of modern technology in agricultural production in accordance with the scheme approved in 2010.

The Nitrogen Use Efficiency (NUE) Technology of Arcadia Biosciences Inc. has been issued a key patent by the State Intellectual Property Office of China. The technology will allow farmers to use significantly less nitrogen fertilizer on their crops and maintain high yields as demonstrated in country trials in important grain crops such as rice and wheat.
In addition, farmers will be able to claim carbon credits from reduced fertilizer use. Nitrogen fertilizer, an essential element in modern agriculture has not been utilized efficiently and contributes to greenhouse gas, which is 300 times more potent than carbon dioxide. With this technology, farmers in China will be extremely benefited by reducing greenhouse gas emission and enhanced food security in the country.
Upon the termination period (April 2012) for the call to comment on the Risk Assessment and Risk Management (RARMP) made by the Australian Office of Gene Technology, a decision has been made to issue a license to Bayer CropScience Pty Ltd to conduct a limited and controlled release of genetically modified (GM) cotton. Eleven GM cotton varieties with insect resistance and herbicide tolerance will be tested in six sites per year in Narrabri Shire (NSW), Wyndham-East Kimberly (WA), and Central Highlands (Qld), between May 2012 and May 2015.
The trial will be conducted to assess the agronomic performance of the GM cotton varieties under field conditions, and to produce seed for use in further studies or releases. The GM cotton will not be permitted to enter human food or animal feed.
A new Economic Impact Assessment of Turkey's Biosafety Law finds that the way in which this law is being implemented has resulted in substantial negative economic impacts for the important Turkish importing, feed and food manufacturing and livestock production sectors.
"There is clear evidence of major economic damage and market disruption having been caused by the way in which Turkey's Biosafety Law is being implemented," said Graham Brookes of UK-based PG Economics Ltd. lead author of the report. "This situation can be expected to get progressively worse, threatening the viability of many Turkish businesses (notably small-and medium-sized enterprises) and risking the export of jobs and investment from the country, unless a timely and science-based Turkish GMO approval system is operated."
Some key findings of the report are:
A discussion paper released by the International Food Policy Research Institute (IFPRI) examined the contribution of Bt cotton adoption to long- term average cotton yields in India using a panel data analysis of production variables in nine Indian cotton-producing states from 1975 to 2009.
The results show that Bt cotton contributed 19 percent of total yield growth over time, or between 0.3 percent and 0.4 percent per percentage adoption every year since its introduction. Besides Bt cotton, the use of fertilizer and the increased adoption of hybrid seeds appear to have contributed to the yield increase over time. However, if official Bt cotton adoption contributed to increased yield after 2005, unofficial Bt cotton might also have been part of the observed increase of yields starting in 2002, the year of its official introduction in India.

President of the Philippine National Academy of Science and Technology (NAST) Dr. Emil Q. Javier, representing the esteemed scientists in the Philippines, reaffirmed their full support to the ongoing research on the fruit and shoot borer resistant Bt eggplant in the country.
Dr. Javier said that the Academy is confident that the Supreme Court will not act rashly but rather consider the scientific side regarding the petition for the writ of kalikasan and writ of continuing mandamus recently filed by a group of NGOs against the conduct of Bt eggplant multi-location field trials.
Dr. Javier added that the filing of the petition is not of national interest, and that the Academy, together with the University of the Philippines and reputable scientists from the local and global community, strongly support agricultural biotechnology. Contrary to the baseless allegations of the petitioners, Bt eggplant is potentially the best environmentally friendly technology for eggplant production, Javier asserts.
The NAST is the highest S&T policy advisory and recognition body of the scientific community in the country.
The Russian government has recently put in place the "Complex Program of Biotechnology Development in Russia (2012 – 2020)" with the signing of Russian Prime Minister Vladimir Putin. The Program aims to put Russia in the leading position in biotechnology and to make the country globally competitive in bioeconomy, nanotechnology and information technology.
The program shall be implemented successively in two phases: 2012-2015 and 2016-2020, and will require a total of 1.18 trillion rubles (USD40 billion). The Russian Federation will develop plant varieties and hybrids which are resistant to drought, diseases, herbicides, pests, and adverse environmental conditions using post-genomic technologies (methods of breeding based on the use of molecular markers) and genetic engineering.

Wheat is one of the most important food crops across the globe. However, there have been no GM wheat varieties available in the market up to the present. The development of biotech wheat could benefit from the use of site-specific recombination systems that involve efficient excision of marker genes used to identify transformants. Thus, USDA scientist James Thomson and colleagues developed a recombination system derived from Mycobacterium smegmati bacteriophage Bxb1. The system is designed to remove the marker gene in GM wheat.
Based on the findings published in the Plant Molecular Biology Reporter, the research team confirmed that Bxb1 recombinase is heritable in GM wheat plants and performs site-specific excision. Therefore, the system is a useful tool for generating marker-free GE plants. Development of wheat lines capable of efficiently excising unneeded marker genes eliminates one potential impediment to commercialization of GM wheat.

David Wangila from Louisiana State University evaluated the performance of Bt corn with pyramided Bt proteins for resistance to sugarcane borer (Diatraea saccharalis). Through leaf tissue bioassay and greenhouse trials, Wangila determined the survival and plant injury of diffrent sugarcabe borer genotypes (Cry1Ab-susceptible, Cry1Ab-resistant and Cry1Ab–heterozygous) on Bt corn hybrids containing single and pyramided Bt genes. Results of the greenhouse trials and the bioassay showed that the survivorship of the sugarcane borer was low in Bt corn hybrids indicating efficacy of the hybrids against all three insect genotypes.
Wangila also assessed the larval movement in various planting patterns of non-Bt and Bt plants. Results showed that the larvae could move from infected plants at least four plants away, and from the infested rows to adjacent rows. With these findings, it is confirmed that pyramiding of Bt proteins is an efficient strategy in the management of sugarcane borer.

Biotech maize MON 88017 has stacked traits for glyphosate tolerance and western corn rootworm (WCR) resistance. A team of scientists headed by O. Habuštová from České Budějovice, Czech Republic, evaluated the possible environmental impacts of MON88017 by comparing communities of spiders in plots planted with biotech maize for 3 years, non-GM counterpart with or without insecticide application, and two unrelated maize cultivars.
Results of the statistical analysis showed that biotech maize had no effect on the abundance and biodiversity of spiders. The composition and the size of the spider communities varied in every year of the study implying the effect of weather and field fertilization with organic matter.

Beyond Crop Biotech
Back in 1998, the Federal Bureau of Investigation (FBI) introduced Short Tandem Repeat (STR) identification to recognize bodies or people and create their profiles. The FBI scans a DNA sample for at least 13 STRs, which are collections of repeated two to six nucleotide-long sequences that are scattered around the genome. The reason why STRs are ideal for creating a unique DNA fingerprint is that the number of repeats in STRs can mutate quickly making each set of these genetic markers different from every other person's.
Now, researchers from Whitehead Institute improved the STR identification, to fit in the present needs of geneticists. The researchers have created lobSTR, which is a three-step system that accurately and simultaneously profiles more than 100,000 STRs from a human genome sequence in one day.
Yaniv Erlich, a researcher in Whitehead Institute, said that with lobSTR, access is now provided to thousands of quickly changing markers that scientists could not get before. This newly opened door can be used in medical genetics, population genetics, and forensics.
For further information about the lobSTR research, follow the link below: http://www.wi.mit.edu/news/archives/2012/ye_0427.html.
Scientists from The Scripps Research Institute are able to explain the chemical pathway that allows bacteria to form clusters known as biofilms. This could lead to the development of new treatments that will block biofilm formation which are involved in several forms of human infection and help bacteria resist antibiotics.
Scripps Research President and CEO Michael Marletta said that there are about 80 percent of human pathogens that form biofilms during some part of its life cycle. "In this study, we have detailed for the first time the signaling pathway from nitric oxide to the sensor through cellular regulators and on the biological output, biofilm formation," he added. Biofilm formation makes the cells in the interior relatively protected from the effects of natural or pharmaceutical antibiotics, thus difficult to kill with conventional treatments. In sufficient quantity, nitric oxide is toxic to bacteria and it could set off the bacteria to enter in its ‘defensive state', as in the biofilm. The Marletta lab focused on how to pull nitric oxide's trigger.
Interactive genes for proteins are often found adjacent to each other, which is why the researchers were able to infer that there is a connection between bacterial Haeme-Nitric Oxide/Oxygen (H-NOX) domain and an enzyme called histidine kinase.
The experiments revealed that histidine kinase transfers a phosphate group to response regulators. These work together to control the biofilm formation. Each regulator has a complementary role, which makes for an oddly complex system. These roles involve activating of gene expression, controlling of the activity of an enzyme producing a bacterial messenger molecule critical in biofilm formation, and lastly, tuning of the degree of activity of the second regulator.

Scientists at Duke University reported that around 70 percent of people have two working copies of a gene linked to an odor receptor (OR7D4) involved in detecting androstenone, a compound present in male pork meat. Individuals with one or no functional copy of the gene can tolerate the smell of the compound much better than those with two copies.
"I was surprised at how cleanly this experiment showed who smelled what," Duke associate professor Hiroaki Matsunami said. "The results showed that people with two copies of the functional variant of the gene for that odor receptor thought that the meat smelled worse with higher levels of androstenone added."
The study addressed the concern about banning of a castration method for swine in Europe. The researchers were curious if consumers would respond to meat from noncastrated males. Noncastrated pigs were found to have higher androstrone levels than the castrated pigs.

The Gram-negative, rod-shaped Oceanimonas sp. GK1, isolated from Gavkhouni Wetland in Iran, belongs to the Aeromonadaceae family. It is a motile aerobic bacterium which can tolerate up to 12% NaCl, grows at 10 to 45°C (optimum, 35°C) and pH 6 to 10 (optimum, 8), and produces large amounts of poly-β-hydroxybutyrate (PHB) as a carbon and energy reservoir under unbalanced growth conditions. PHB is a biodegradable and renewable biosynthetic polymer which can be used in medicine, tissue engineering, and packaging materials. Despite these features the Oceanimonas species are relatively poorly characterized in terms of genetic and genome characteristics. The whole genome sequence of this strain is the first report of a completely sequenced and annotated genome from the Oceanimonas genus.
The whole-genome sequencing resulted in a single circular chromosome of 3,514,537 bp and two plasmids 8,462 and 4,245 bp in length. The complete Oceanimonas sp. GK1 genome has been deposited in GenBank under the accession no.CP003171 for the chromosome and CP003172 and CP003173 for the two plasmids. The genome project data are also available at GenBank under the Genome Project identification number (ID) 68171.
