Abstract excerpt
KEY MESSAGE: Natural variation at the WRKY53-C518G SNP drives cold tolerance divergence between rice subspecies. The japonica-specific WRKY53518C allele, originating from Chinese wild rice and selected in temperate regions, confers cold tolerance by reducing GA repression to protect pollen fertility, and thus provides a valuable target for rice breeding. Cold tolerance at the booting stage (CTB), when...
