【Abstract】 Transgenic plants were generated exhibiting insect resistance due to the introduction of following genes, such as Bt cry gene and CpTI gene, etc. They have been successfully used to protect from insect attack in recent years. In this paper, advances on the engineered plants were reviewed. The problems on how to increase the level of expression and to limit the development of insect resistance were also discussed.更多还原
