Abstract

The invention belongs to the technical field of plant genetic engineering, and particularly relates to application of an OsMAPKK4 gene in improving disease resistance of rice, particularly the application in controlling resistance of rice to bacterial blight and bacterial leaf streak. Through research on overexpression of the OsMAPKK4 gene, it is found that the OsMAPKK4 gene can influence the resistance of rice to bacterial leaf blight and bacterial leaf streak, and the overexpression of the OsMAPKK4 gene improves the resistance of rice to bacterial leaf blight and bacterial leaf streak. The OsMAPKK4 gene can be applied to disease-resistant breeding of rice.

Description

technical field

[0001] The invention belongs to the technical field of plant genetic engineering, and specifically relates to the application of the OsMAPKK4 gene. The gene is the rice OsMAPKK4 gene, and the gene can be used to enhance the cultivation of rice varieties with broad-spectrum resistance to bacterial blight and bacterial streak disease. Background technique

[0002] The disease resistance genes in rice can be mainly divided into two categories: main disease resistance genes and disease resistance related genes. Among them, the main disease resistance genes are also called R genes, which are usually only resistant to one or a few pathogenic races. Resistance genes, such as cloned Xa21, xa13, Xa3 / 26, Xa1 / 2 / 14, etc.; disease resistance genes other than the main disease resistance genes are called disease resistance-related genes, such as OsWRKY45, OsWRKY13, OsEDR1, OsPAD4, etc. At present, the R gene is more widely used in production, but the resistance mediated by ...
