Basic Information
CGSNL Gene Symbol PIA
Gene Symbol Synonym Pi a, Pia, Pi-a, Pia-1, Pia-2
Gene Name Synonym Pyricularia oryzae resistance-a, Magnaporthe grisea resistance-a, Blast resistance a
Protein Name
Chromosome No. 11
Explanation Resistant to rice blast disease. Variety 'Aichiasahi' has this gene. Pia is composed of two adjacent genes SasRGA4 (Sasanishiki allele of Os11gRGA4) and SasRGA5. Os11gRGA4: AB604621-AB604625, Os11gRGA5: AB604626-AB604630. (Okuyama et al. 2011) Among the four candidate genes (Os11g0224900, Os11g0225000, Os11g0225100 and Os11g0225300), Os11g0225100 was identified as the most promising candidate for Pia (Zeng et al. 2011).
