植物蛋白酶抑制剂及其在林木抗虫基因工程中的应用

植物蛋白酶抑制剂是除Bt之外又一个愈来愈研究较多的抗虫基因资源,其分布广泛,在豆科、茄科、禾本科、葫芦科及十字花科等植物中存在较多。植物蛋白酶抑制剂抗虫基因主要通过2种途径获得并在多种植物中进行转化,获得抗虫转基因植株。植物蛋白酶抑制剂在林木抗虫基因工程中的应用刚刚起步。本文在总结我国林木病虫害防治现状的基础上,阐述植物蛋白酶抑制剂在林木抗虫基因工程中的应用前景,同时也探讨植物蛋白酶抑制剂在林木害虫防治应用中存在的问题及解决途径。

Plant Protease Inhibitors and Their Application on Forest Tree Resisting Pest Genetic Engineering

Plant protease inhibitors as a resisting pest resource was more studied besides Bt gene, the distribution is widely, especially in the leguminosae, solanaceae, gramineae, cucurbitaceae and cruciferae plants. Plant protease inhibitors resisting gene was mainly acquired by two methods and had been transferred in some plants, and obtained the resisting pest genetic engineering plants. Plant protease inhibitors was preliminary applied in the forest trees resisting pest genetic engineering. In this paper, based on the control status of forest trees pest in China, application prospects of plant protease inhibitors in control pest were systematically discussed, meanwhile, the existing problem and solving methods of plant protease inhibitors were also put forward in control of forest tree pest.
