Abstract
The present application relates to the field of biotechnology, more particularly, the present application relates to a mutant insecticidal protein Vip3 and its application. The present application obtains the mutant insecticidal protein Vip3 which can be highly expressed in plant cells and has excellent insecticidal effect on various pests by point mutation on the original Vip3 family protein sequence, and the toxicity of the mutant insecticidal protein Vip3 to plant cells is reduced.
