Abstract

The invention relates to the technical field of genetic engineering, in particular to application of a brown planthopper PIB14 protein and a coding gene thereof to regulation and control of brown planthopper resistance of plants. According to the invention, the brown planthopper PIB14 protein and a sequence of the coding gene thereof are found, and the gene has the great significance for regulating and controlling the resistance of plants to brown planthoppers and regulating and controlling the growth of the brown planthoppers. The viability of the brown planthopper can be effectively reduced by inhibiting expression of the PIB14 gene in the brown planthopper, the resistance of the plants to the brown planthopper can be effectively improved by overexpressing the PIB14 gene in the plants, and the brown planthopper PIB14 protein and the coding gene thereof found by the invention have very good application prospect, and have high application value of reducing the use of pesticides and maintaining ecological balance and sustainable development.

Description

technical field

[0001] The invention relates to the technical field of genetic engineering, in particular to the application of brown planthopper PIB14 protein and its coding gene in regulating plant resistance to brown planthopper. Background technique

[0002] Brown planthopper (BPH; Nilaparvata lugens Stal.), belonging to the family Homoptera (Delphacidae) of the order Homoptera, is one of the main pests on rice. The brown planthopper has the habit of long-distance migration and is a monophagous pest. It can only feed and reproduce on rice and common wild rice. The piercing-sucking mouthparts of the brown planthopper can penetrate the plant and suck the phloem juice. The brown planthopper not only feeds on the phloem sap and causes direct damage, but also causes indirect damage as a medium for the transmission of grassy dwarf disease and leaf dwarf disease. Brown planthopper feeding on rice before tillering stage will reduce the number of spikes and grains of rice; whil...
