- ... The Pi-z gene in rice confers resistance to a wide range of races of the rice blast fungus, Magnaporthe oryzae. The objective of this study was to characterize Pi-z in 111 rice germplasm accessions using DNA markers and pathogenicity assays. The existence of Pi-z in rice germplasm was detected by using four simple sequence repeat (SSR) markers (RM527, AP4791, AP5659-1, AP5659-5) closely linked to ...

- ... Rice blast, caused by fungal pathogen Magnaporthe grisea Barr., is one of the most devastating rice diseases worldwide. It has greatly affected the rice production and quality. Development of resistant cultivars is the most effective and economical way for controlling this disease in rice. In this study, 114 of the single-segment substitution lines (SSSLs) in rice were inoculated at seedling stage ...
