British "natural" website published a new study found that a particular gene can spread in a large number of mosquito populations, which will greatly promote the use of genetically modified mosquitoes for malaria control Research.

In genetically modified mosquitoes fight malaria, the past studies have found some to reduce the mosquito-borne malaria ability to specific genes, but the problem is that if these genes can not be in the wild mosquito population to spread rapidly, even in the environment, put some transgenic mosquitoes , it will not play much role.

Researchers at Imperial College London and international colleagues report that they found a gene can help to solve this problem, which will guide the synthesis of a gene called I-Scel the enzyme, and this enzyme in the mosquito play a role in reproduction, the result is all the sperm of male mosquitoes will contain this enzyme, the gene will be passed to the next generation, and will for generations.

Grown in the lab researchers to put a small amount of mosquito populations of mosquitoes containing the gene, the results after 12 generations of mosquito breeding, which is a few months time, half the entire mosquito population carries the gene.

Therefore, if a mosquito-borne malaria, can reduce the ability of the gene and the gene bound together, and then running the GM mosquitoes into the environment, the effect of malaria will be greatly enhanced.sanderlu.net ebook web
