Viral Lectin Gene of a Polydnavirus and Its Products and Their Use

摘要

The present invention rutel program Kochi punishment (Cotesia plutellae) poly and out of the symbiotic virus (Cotesia plutellae Polydnavirus: CpBV) derived lectins (lectin) genes and their products and their insect immune suppression of the will. In the present invention reveals that the polyester and out to remove the lectin gene in a virus (CpBV), and suppress the immune recognition is made that within the parasite living body through the expression of the gene is directly attributable to the mechanism of the gene. In the present invention, it reveals the insect immunosuppressive functions of the protein product is a poly encoding and out virus-derived lectin gene. On the basis of these findings, in the present invention for expressing the combinations etc. and out poly virus-derived lectin gene and the E. coli this vector, the expression of the lectin protein chain is provided with its purpose. Lectin gene product of the present invention can also be used as the sole pesticide, in particular greatly improve the ability of the existing insecticidal pesticides containing the biopesticide when used with by lowering the recognition capability of the pathogen. ; Kochi rutel program suits, polyester and out viruses, lectins, cabbage moth, immune response
