Bt Toxic Protein Gene and Gene Engineering of Insect resistant Plant

Ｂｔ毒蛋白基因与植物抗虫基因工程林良斌官春云（作物基因工程湖南省重点实验室，湖南农业大学长沙４１０１２８）在世界范围内，害虫造成的损失约占农作物总收获量的１３％，每年大约损失数千亿美元。目前，防治害虫仍然是主要地使用化学农药，但随着时间推移，由此而引...

The family of Bt toxic protein gene was introduced. The advances of the application of Bt toxic protein gene in gene engineering of insect resistant plant were reviewed from aspects of transgenic plant, artificial reform of Bt toxic protein gene expression of Bt toxic protein gene and insecticidal activity of transgenic plant, the development of insect′s resistance aganst Bt toxic protein. The problems of Bt toxic protein gene engineering and resolving ways were discussed.
