The use of disease-resistant varieties is an effective, economical, and environmentally-friendly means to control genes against genetic diseases.
Recently, the teams of Liu Junfeng and Peng Youliang from the College of Plant Protection of China Agricultural University obtained rice blast resistant to rice by artificially designing rice immune receptors
On the basis of revealing the structural characteristics of MAX-type effector protein AvrPib and the interaction mechanism between the decoy domain RGA5-HMA and the effector protein in the NLR protein in the early stage, the researchers modified the RGA5-HMA domain and successfully designed a design that can identify non-correspondence.
The establishment of this system and the success of the measures will provide important technical guarantees for the breeding of multi-line varieties to guide the hybridization and layout of varieties, and the breeding of rice varieties with broad-spectrum resistance genes for disease resistance, so that crops based on molecular design for durable disease-resistant breeding Becomes possible
