Abstract
The present disclosure provides a rice planthopper-sensitivity gene BGIOSGA015651 and the use thereof. The applicant found a gene BGIOSGA015651 for regulating rice planthopper-resistance by studying on rice varieties BG1222 and TN1. The gene expression level of BGIOSGA015651 in the insect-resistant variety is hundreds of times or more different from that of the insect-susceptible variety. The expression of this gene can be reduced or knocked out by molecular breeding methods or genetic engineering methods, resulting in that the insect-susceptible plant can obtain high insect-resistance. The resistance level of the insect-susceptible rice variety TN1 is of level 9 before knock-out, and the resistance level thereof is significantly increased to level 0-1 after the rice planthopper-sensitivity gene BGIOSGA015651 is knocked out. The gene and the encoded protein thereof can be used for plant genetic improvement, and the obtained rice for breeding can be widely promoted in a wide range of rice growing areas, and has high economic values and outstanding ecological benefits.
