Genetically modified soybeans

( Update: 23/07/2015 )

Genetically modified soybeans are the dominant technological achievements yield, pest resistance, resistance papilio ... no evidence to prove environmental harm.

Cuu Long Delta Rice Research Institute has "Create lines of soybean (soy) transgenic insect resistance, drought tolerance," and "Choose to create genetically modified soybean varieties resistant borer flies, bollworms" success.

The results have created transgenic lines carrying resistance genes selectively through deep soycry1Ac from T0 to T5 generation by Southern blot analysis (line T0, T1, T2 and T3), RT-PCR (line T3, T4 ) and Western blot (line T5).

Some lines exhibited high resistance to pests and tested in the laboratory and greenhouse. Chose to create multiple lines of transgenic insect resistant gene but does not carry soycry1Ac bookmark bar selection.

Research generated select drought-tolerant soybean line (vector NFP-rd29A-drebIA): Results of PCR analysis of T0 line 8 herbicide resistance has 5 lines with the presence of genetic tolerance to drought drebIA. Rice Research Institute has developed a technical process in the genetic transformation of soybean.

Research and the selection of genetically modified soybean varieties resistant borer flies, bollworms, has designed a new 4-vector insect resistance gene cry2Aa, cry4A, cry2Aa + soycy1Ac, cry4A + soycry1Ac; created transgenic lines from the same generation William T2 were identified by Southern blot analysis or Vip3A soycry1Ac gene.

ELISA analysis of gene flow soycry1Ac T2 recorded significantly the expression of Cry1Ac. Experiments bollworm resistance of line T2, T3 Vip3A gene in natural conditions in a greenhouse plant showed a line of transgenic pest ratio is very low compared to similar non-transgenic controls.
Show soybeans is genetically modified crops occupy the largest area in the total area of GM crops worldwide (60%), followed by maize (22%) and cotton (11%).

In Vietnam, soybeans are important food crops, high consumer demand. However, due to many factors affecting such pests, drought tolerant low ... so low soybean yields, on average only about 1.9 tons / ha.

Therefore, the topic "Research in biotech soybean and soybean lines generated transgenic insect resistance in Vietnam" by Dr. Tran Thi Cuc Hoa, Mekong Delta Rice Institute as chairman, successfully opened more promising.

Dr. Tran Thi Cuc Hoa commented: "genetically modified soybean is a dominant technological achievements yield, pest resistance, resistance papilio ... no evidence to prove harm environment.

Even the genes and proteins when introduced into the already cooked, there are many research results demonstrate decompose at high temperatures. Therefore there is no basis to say that eating genetically modified food will cause damage to people and the environment.

"With three plants that the government has a policy to put in SX is corn (maize), soybeans and cotton I think reasonable. Because these 3 crops this country has had to import large quantities. But I think it is important that the communication needs to make people understand, take cultivation of genetically modified crops.

Genetically modified crops with insect resistance traits, only in terms of pest (native plants are not resistant to) the advantages are emerging. In normal conditions, the transgenic plants would not solve the problem of increasing productivity ... "she said Hoa.

After the results of successful research genetically modified soybean, before making the actual plant to assess the impact of risk. Experiencing this stage find new safe transition phase and small trials found no effect on the ecological environment, microorganisms ... will move to stage large-scale planting.
