  Magnaporthe oryzae, the rice blast pathogen, causes significant annual yield loss of rice worldwide. Currently, the most effective disease control approach is deployment of host resistance through introduction of resistance (R) genes into elite cultivars. The function of each R gene relies on the specific recognition of an avirulence (AVR) gene of the pathogen. However, the introduced resistance can be broken down within a few years, due to mutation of the AVR genes in the field populations. It is known from a few case studies that AVR mutation patterns are different from one to another. Therefore, knowledge of AVR genes sequence diversity serves as fundamental background in introducing new resistance to control rice blast. In this study, we focused on a newly identified AVR gene AvrPiz-t. We PCR amplified open reading frames (ORFs) of AvrPiz-t as well as promoter regions to detect size .. View More»
