Rice blast is caused by  Magnaporthe oryzae , which is the most destructive fungal pathogen affecting rice growing regions worldwide. The rice blast resistance gene  Pib  confers broad-spectrum resistance against Southeast Asian  M. oryzae  races. We investigated the allelic diversity of  Pib  in rice germplasm originating from 12 major rice growing countries. Twenty-five new  Pib  alleles were identified that have unique single nucleotide polymorphisms (SNPs), insertions and/or deletions, in addition to the polymorphic nucleotides that are shared between the different alleles. These partially or completely shared polymorphic nucleotides indicate frequent sequence exchange events between the  Pib  alleles. In some of the new  Pib  alleles, nucleotide diversity is high in the LRR domain, whereas, in others it is distributed among the NB-ARC and LRR domains. Most of the polymorphic amino acids in LRR and NB-ARC2 domains are predicted as solvent-exposed. Several of the alleles and the unique SNPs are country specific, suggesting a diversifying selection of alleles in various geographical locations in response to the locally prevalent  M. oryzae  population. Together, the new  Pib  alleles are an important genetic resource for rice blast resistance breeding programs and provide new information on rice- M. oryzae  interactions at the molecular level.
