德里大学声称已经开发出更好的Bt棉花

 

DU researchers claim to have developed better Bt cotton

By combining two genes which can improve its output of Bt toxins, a research paper from Delhi University has claimed to have hiked Bt cotton's level of resistance to pests.

The amount of Bt toxins produced, when the two genes are combined in a cotton plant rises by 4 to 5 times higher than those available in the market currently.

According to the paper, this development can prove crucial in dealing with insect attacks that may increase because of global warming.

In recent times, pink bollworm has been able to break the protection provided by currently available Bt cotton.

As per the researchers, one Bt toxin protein is targeted at the cytoplasm while the other is targeted at the plastids that are the site of photosynthesis and many other biochemical pathways in the plant.

德里大学声称已经开发出更好的Bt棉花

通过结合两个基因可以改善Bt毒素的产出, 德里大学的一篇研究论文声称已经提高了Bt棉花抗害虫的水平。

当这两个基因结合在一棵棉株上，Bt毒素产生的数量比当前市场上可用的上升了4到5倍。

报道称,这种发展可以证明处理昆虫攻击的关键,因为全球变暖可能会增加。

近年来,棉红铃虫已经能够打破目前对Bt棉花提供的保护。

根据研究人员,一个Bt毒素蛋白是针对细胞质,而另一个则是针对的叶绿体的光合作用和其他植物的生化途径。
