Rice blast resistance gene pikg, encoded protein and its application

Abstract

The invention discloses a rice blast resistance gene Pikg, encoded protein and application thereof, belonging to the field of rice disease resistance breeding. The rice blast resistance gene Pikg includes Pikg-1 and Pikg-2, and the nucleotide sequence of its coding region and the amino acid sequence of its encoded protein are respectively shown in the sequence table. The gene and protein of the invention can be used to improve the resistance of rice plants to blast fungus.

Description

technical field

[0001] The invention belongs to the field of rice disease-resistant breeding, and in particular relates to a rice blast resistance gene Pikg, encoded protein and application thereof. Background technique

[0002] Rice (Oryza sativa L.) is an important food crop. More than half of the population in my country takes rice as a staple food. Therefore, maintaining and increasing rice production is of great significance to maintaining food security in our country. However, the yield of rice is affected by various diseases and insect pests. Among them, the fungal disease rice blast, sheath blight and bacterial disease bacterial blight are called the three major diseases of rice due to their serious damage. Among the three diseases, rice blast caused by Magnaporthe oryzae has a high incidence frequency, strong prevalence, and a wide range of impacts. According to statistics, the rice yield loss caused by rice blast is as high as 10%-30% every year. . The traditiona...
