Yang et al. (2009) firstly mapped a blast resistance gene Pi41, and another two novel blast resistance genes, Pi60(t) and Pi61(t), were identified and mapped, showing resistance frequency as high as 86.5% of 495 strains collected from indica and japonica derived rice materials (Lei et al. 2013), and Pi41 conditioned complementary reactions to another 15 blast R genes (including Pi2) under infection with blast isolates (Yang et al. 2009), thus represents a enhanced component for R gene-stacking for enhanced blast resistance in hybrid rice. This evidence concerns the gene SERPINB1 and infection.
