Basic Information
CGSNL Gene Symbol PI33
Gene Symbol Synonym Pi33(t), RMg70, Pi-33(t), Pi-33, Pi33
Gene Name Synonym Pyricularia oryzae resistance-33(t), Magnaporthe grisea resistance 33, Blast resistance 33
Protein Name
Chromosome No. 8
Explanation Pi33 was located on chromosome 8 in a 1.6cM interval between markers RM72 and Y2643L (Bohnert et al. 2004). Original line is IR64, Bala (Indica). It was shown that, in the elite rice variety IR64, the resistance conferring allele of the rice blast resistance gene Pi33 was introgressed from the wild rice Oryza rufipogon (accession IRGC101508). The Pi33 locus was previously mapped to a 240 kb region between markers RMSPi33-53 and RM3507. In Nipponbare, nine candidate genes (three NBS-LRR and six LRR-kinase) were identified in this genomic region: (LOC_Os08g10250, LOC_Os08g10260, LOC_Os08g10290, LOC_Os08g10300, LOC_Os08g10310, LOC_Os08g10320, LOC_Os08g10330, LOC_Os08g10430 and LOC_Os08g10440) (Ballini et al. 2007). The Pi33 gene is located at a position of 3,306-3,309 Mbp inside the LOC_Os08g32600 (Os08g0421800) locus. (Utami et al. 2011).
