Cabbage proteinase inhibitor gene confers resistance against plant pests

摘要

The present invention relates to a DNA construct containing a DNA for a serine proteinase inhibitor isolated from Brassica oleracea, which has antibiosis activity. The present invention also relates to transgenic plants and transgenic plant seeds containing that nucleic acid molecule. Resistance to herbivorous insects can be conferred to a plant by either transformation of the plant with the nucleic acid molecule which encodes a serine proteinase inhibitor isolated from Brassica oleracea or by application of that inhibitor to plants or plant seeds.
