BIOTIC PESTICIDE COMPOSITION COMPRISING GALECTIN

摘要

PURPOSE: A biotic pesticide containing galectin and Bacillus thuringiensis is provided to effectively prevent plant damage due to pest, and to develop improved biotic pesticides. CONSTITUTION: A composition for biotic pesticide aid contains galectin as an active ingredient. A biotic pesticide composition contains Bacillus thuringiensis. A polynucleotide encodes galectin with a base sequence of sequence number 1. An expression vector contains the polynucleotide. A transformant is prepared by introducing the expression vector into a host cell to express galectin. The biotic pesticide composition contains the transformant. A pesticidal method comprises a step of treating a region in which pest inhabits, with the biotic pesticide composition.
