The method that finds Resistance Gene Analogs (RGA) using the degenerate primers designed based on the conserved motifs of plant disease resistance genes (R) was named as RGA method.

• 植物抗病基因(Resistance Gene,R)产物存在保守结构域,如NBS、LRR、STK、TIR、TM和LZ等。 根据这些保守序列设计简并引物寻找R基因同源序列(Resistance Gene Analogs,RGA)的方法称为RGA法。
