GHANA FORMULATES BIOSAFETY FRAMEWORK

Christine Churcher, Ghana's Minister of Environment and Science, recently launched the country’s National Biosafety Framework in Accra, Ghana. This framework is meant to ensure an adequate level of production in the field of safe transfer, handling, and use of living modified organisms resulting from modern biotechnology.

“By the accession,” Ms. Churcher said, “We affirm our position for the safe use, handling, and transportation of genetically modified organisms that might find [their] way to Ghana.” She assured Ghanaians that all GMOs will pass through rigorous inspection to ensure that they conform to the country's regulations and standards.

Edward Nsenkyire, Chief Director of the Ministry of Environment and Science, stressed that Ghana's position on the issue is strictly based on the precautionary principle, and that every effort will be made to ensure safety in the use of GMOs. Professor Alfred Oteng-Yeboah, Chairman of the National Biodiversity Committee, said that with the national framework in place, wildlife and other organisms in Ghana would be adequately cared for and protected.

CALL FOR BIOTECH DEVELOPMENT IN BANGLADESH

Bangladesh has to focus on capability building in both public and private sectors to encourage biotechnology development in the country. This was stressed by Dr. M.A. Halim Khan, Vice Chancellor of the BSMR Agricultural University, who served as chief guest during the workshop on “Reporting biotechnology: Issues and opportunities for the news media” held at the BRAC Centre, Dhaka.

Abdul Awal Mintoo of the East-West Seed Co. in Bangladesh said that his company was committed to spend TK20 crore or more to develop a modern biotechnology laboratory in Bangladesh. Biotechnology experts who spoke during the workshop called for efforts to create greater public awareness on biotechnology particularly with regards the issue of safety. It was announced that while biotech crops are not yet commercially planted in Bangladesh, seeds of Golden Rice have already been brought into the country for experimentation at the Bangladesh Rice Research Institute. Biosafety guidelines have been set and are awaiting approval.

The two-day workshop was organized by the International Service for the Acquisition of Agri-Biotech Applications (ISAAA) Bangladesh Office, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), and Syngenta Foundation for Sustainable Agriculture. More information about the workshop can be obtained from KM Nasiruddin, ISAAA Bangladesh country coordinator, at k.nasiruddin@isaaa.org.

Dr M A Halim Khan, Vice Chancellor of the BSMR Agricultural University, calls for greater initiatives in biotechnology.


EU OKS BIOTECH RAPESEED AS ANIMAL FEED

The European Commission has given a 10-year permission to Monsanto Co. for a herbicide resistant rapeseed to be imported into 25 nations for animal feed. This is the Commission’s second approval of a Monsanto-developed product, the first being a biotech corn product resistant to rootworm also for animal feed.

Known as GT73, the rapeseed product was pronounced to be safe as conventional oilseed in a scientific evaluation conducted earlier. It is currently grown in the United States, Australia and Canada and is allowed for sale in those countries including Japan, the Philippines and South Korea.

TRANSGENIC ALFALFA PRODUCES ISOFLAVONES

Isoflavonoids are an interesting group of compounds: they are produced mostly by legumes in response to plant stress, but have also shown potential in combating hormone-dependent cancers, cardiovascular disease, osteoporosis, and menopausal symptoms. Engineering isoflavonoid biosynthesis in plants can thus provide a good source of these compounds, for plant-based dietary supplements, and for providing plants extra defense mechanisms.

Bettina E. Deavours and Richard A. Dixon of the Samuel Roberts Noble Foundation set out to perform “Metabolic Engineering of Isoflavonoid Biosynthesis in Alfalfa.” They engineered alfalfa leaves to produce genistein glucoside without affecting regular plant growth or the expression of other alfalfa genes. Their findings appear in the latest issue of the Plant Physiology journal.

Using the IFS gene from the model legume Medicago truncatula, or the barrel medic, researchers successfully generated transgenic alfalfa producing, among other isoflavonoids, genistein. Since genistein is not normally synthesized in alfalfa leaves, scientists used microarrays to track if its accumulation caused any unexpected effects on gene expression. Tests showed, however, that gene expression carried on as usual.

FINDINGS ON MEXICO MAIZE RELEASED

Sometime in 2000, scientists released research findings that stated that they had found evidence of genetically modified corn in maize landraces grown in Oaxaca, Mexico. This was significant, because transgenic maize has never been approved for cultivation in the country.

Five years later, S. S. Ortiz-García and colleagues publish their findings in the Proceedings of the National Academy of Sciences. Their article, “Absence of detectable transgenes in local landraces of maize in Oaxaca, Mexico (2003–2004),” is published in the journal’s latest electronic edition.

Researchers worked on 70 plants in 125 fields and 18 localities in the state of Oaxaca during 2003 and 2004. They performed the polymerase chain reaction (PCR) on DNA samples from 153,746 sampled maize seeds, screening for the 35s promoter of the cauliflower mosaic virus and the nopaline synthase terminator from Agrobacterium tumefaciens, with the PCR reaction optimized to detect at least 0.01% transgenic material. One or both of the transgene elements are present in all transgenic commercial varieties of maize.

PCR could not detect any transgenic sequences in the seeds sampled, and authors conclude that transgenic maize seeds were absent or extremely rare in the sampled fields. They, however, caution readers about the limitations of their research. For instance, their seed sampling may not have been thorough, and the samples could be less than representative of the local maize crop. They also caution readers from extrapolating the findings to other regions of Mexico, or from considering the current situation likely to remain unchanged.

BRASSICA GENE IMPROVES STRESS TOLERANCE IN CHINESE CABBAGE

Late embryogenesis abundant (LEA) protein genes are expressed by plants during the later stages of seed development, but may also be expressed when plants are exposed to environmental stresses. This means that engineering LEA genes into plants could give these plants a chance to survive under environmental stresses, such as salinity and drought.

In the September issue of the Journal of Plant Science, Byong-Jin Park of Tohoku University, Japan and colleagues report the successful “Genetic improvement of Chinese cabbage for salt and drought tolerance by constitutive expression of a B. napus LEA gene.” Chinese cabbage is an important vegetable in Asia, especially in China, Korea, and Japan.

Using Agrobacterium transformation, as well as the LEA gene from Brassica napus, researchers transformed cabbage cells, regenerated the plants, and subjected them to various stress conditions. They found that 1) transgenic cabbage germinated even at high salt concentrations, while non-transgenic cabbage did not; 2) seedlings of transgenic plants remained healthy during high salinity stress, while those of non-transgenic plants wilted; 3) non-transgenic plants wilted after two weeks of water deprivation, while transgenic plants continued to grow; and 4) resupplying water to the plants allowed transgenic plants to keep on growing, while non-transgenic plants were no longer able to recover.

ARABIDOPSIS LENDS SALT TOLERANCE TO POTATO PLANTS

Plant cells accumulate proline when under drought and salt stress, as it can protect cellular structures from drying out. The gene for pyrroline-5-carboxylate synthetase (P5CS) has been found to increase proline production. Once introduced into rice, wheat, and carrot plants, the gene has also been found to increase tolerance to salt stress.

Aida Hmida-Sayari and colleagues work on another crop this time, as they report that the “Overexpression of ?1-pyrroline-5-carboxylate synthetase increases proline production and confers salt tolerance in transgenic potato plants.” Their research appears in the October issue of the Journal of Plant Science.

Researchers transferred the Arabidopsis P5CS gene to potatoes through Agrobacterium transformation, and found that the transgenic potato plants accumulated proline and grew in high salinity conditions. They also found that the high salt stress lowered tuber yield and weight by as much as 63% in non-transgenic potato lines, while tubers from transgenic lines were not as greatly affected.

Of Legends Written in Bamboo and Bones: Agricultural Practices During China's Hsia Dynasty

The world’s largest, most densely populated country is also one of the most ancient sites of civilization. China is bound and interspersed by nearly all kinds of environments, from seas, to deserts, to forests, to mountains. In the north, its Great Plain covers more than 300,000 square kilometers, and is outlined by the Yellow River and the mighty Yangtze, making it a fertile land for agriculture, conflict, and history.

Did You Know?

During the nine-year period 1996 to 2004, the global area of biotech crops increased more than 47 fold, from 1.7 million hectares in 1996 to 81.0 million hectares in 2004, with an increasing proportion grown by developing countries. More than one-third (34%) of the global biotech crop area of 81 million hectares in 2004 was grown in developing countries where growth continued to be strong. It is noteworthy that the absolute growth in biotech crop area between 2003 and 2004 was, for the first time, higher for developing countries (7.2 million hectares) than for industrial countries (6.1 million hectares). The increased hectarage and impact of the five principal developing countries (China, India, Argentina, Brazil and South Africa) growing biotech crops is an important trend with implications for the future adoption and acceptance of biotech crops worldwide.

For relevant information on the global status of biotech crops, visit the Global Knowledge Center's website (http://www.isaaa.org/kc).
