To determine if the C923-49 resistant rice accessions with polymorphic RGA5 HMA domains, perceive AVR1-CO39 and AVR-Pia, infection tests were performed with the M. oryzae isolate Guy11 transformed with an empty vector construct (EV), AVR1-CO3944 or AVR-Pia45. The gene discussed is NLRP6; the disease is infection.
