[Chang-Sheng Wang] Two genomic regions of a sodium azide induced rice mutant confer broad-spectrum and durable resistance to blast disease.
Lo, Kuan-Lin et al., 2021 Rice
A broad-spectrum blast resistant rice mutant line SA0169 was obtained by the sodium azide mutagenesis. Two regions Pi169-6(t) and Pi169-11(t) were mapped with the integration of BSA, Axiom array, Mut-Map methods and functional validated by genome editing. The two regions on chromosomes 6 and chromosome 11 provide completely resistant against the 187 blast isolates and displayed durable resistance for almost 20 years.
