China to produce salt-resistant, resistant to drought and infertile genetically modified alfalfa varieties

Hua,, Lanzhou December 7 (reporters Zhu Guoliang and Gao Jianjun)-located in Northwest region of Lanzhou University, China successfully developed a new genetically modified alfalfa line, has strong ability of salt-resistant, resistant to drought and infertile, could provide grassland industry development in arid area of Northwest China to create a new situation.　　In charge of this study, Lanzhou University Professor Wang Suomin said: "at present, this new genetically modified alfalfa line has been approved by the Office of the Ministry of agriculture, agricultural genetically altered biological products safety management field test, mark transgenic breeding work has entered into this study has important practical significance."　　Wang Suomin said, the reason for salt-resistant, resistant to drought and infertile, is because the aggregates-desert Xeric plants of the new strain-stress tolerance function of the genes of the King, Overlord is a growth in the Northwest desert area of Xeric plants, with a strong vitality. In 1998, Wang Suomin and his colleagues in the ALXA area, Inner Mongolia during the visit of
Note that despite the extremely arid desert, serious deficiency of nutrient elements in the sandy soil and dry-hot wind hit from time to time, and animal grazing, but the growth of the King was good.　　Since then, Wang Suomin led his colleagues, students and others more than 10 people after more than 10 years of unremitting efforts, the clone fighter stress tolerance function of genes, and aggregate it into fine forage grass alfalfa, to boost alfalfa drought resistance and salt resistance and ability to withstand infertile. "We found that adapt to arid and infertile environments of the King of the most effective strategy is to absorb and accumulate sodium, sodium rather than like most cultivated crops refused discharge."　　On this basis, Wang Suomin developed a can significantly improve the ability of desert plant drought-resistant sodium compound fertilizer, with independent intellectual property rights successfully cloned Tyrannosaurus Rex features drought-resistance genes and their resistance genetic improvement for alfalfa forage. Wang Suomin said that alfalfa is known as the King of grass, but its salt resistance and resistance to drought and infertile
Is not strong, only of alfalfa planted in cornfields in better conditions of water and fertilizer in order to achieve an ideal production, resulting in a situation of grain, and a large number of vegetation such as desertification, salinization of land cannot be used effectively. "Transferred to the fighter features drought-resistance genes like alfalfa to a change of heart, allow it to better adapt to drought, salinity and poor soil."　　Wang Suomin, "said experiments showed that compared to ordinary varieties of Medicago sativa, that new transgenic line in moderate to severe salinization can also grow well under the circumstances, in case of severe drought can survive, once you have water, you can quickly return to growth." Wang Suomin said that after breeding genetically modified alfalfa varieties, such as large areas to promote, on the one hand to contradictions that resolve the grain races, promote the development of grassland and animal husbandry in arid area of Northwest China; on the other hand salt can also be improved, the use of large areas of wasteland, improving the ecological environment, which could provide grassland industry development in arid area of Northwest open
