High-resolution genetic mapping of a novel bacterial blight resistance gene xa-45(t) identified from Oryza glaberrima and transferred to Oryza sativa.

A novel recessive bacterial blight resistance locus designated as a xa-45(t) was identified from Oryza glaberrima accession IRGC 102600B, transferred to O. sativa and mapped to the long arm of chromosome 8 using ddRAD sequencing approach. The identified QTL spans 80 kb region on Nipponbare reference genome IRGSP-1.
