Description | xa13 is a recessive R gene conferring resistance to bacterial blight disease which is caused by Xanthomonas oryza pv. oryzae (Xoo). Fine-mapping of xa13 reveals two condidate genes of xa13, one is a homologue of proline-rich extensin-like gene and the other is a homologue of nodulin MtN3. The expression level of xa13 is very low in leaves but quite high in panicles and anthers. Suppression of xa13 expression by RNAi enhance xa13-mediated resistance, it indicates the loss of function of xa13 allele is required for bacterial blight resistance. | ||||||||
Curator Comment | Dominant allele of Xa13 was identified from susceptible rice line IR64. Suppression of Xa13 significantly incresed the resistance of PXO99, but reduced spikelet fertility caused by male sterility (mostly abortive pollen). |
