[Protease inhibitors: use to increase plant tolerance to insects and pathogens]

The review deals with analysis of the possibility of the use of genes of inhibitors of proteolytic enzymes of plants to increase plant tolerance to insect pests and phytopathogens. The idea of using protease inhibitors for plant defense is strongly supported, first, by their wide distribution in plant tissues and high activity towards various proteolytic enzymes of insects, bacteria and fungi. The results obtained for the last years indicate that the genetic engineering approach is perspective for solving of this kind of problems. The main losses and advantages of the discussed approach are also considered. The described approach for increase of plant tolerance to insects and pathogens has few advantages as compared to traditional ones and belongs to ecologically pure technologies.
