Summary Soil salinity has negative impacts on food security and sustainable agriculture. Ion homeostasis, osmotic adjustment reactive oxygen species scavenging are the main approaches utilized by rice to resist salt stress. Breeding cultivars with high tolerance (ST) yield is a significant challenge due lack of elite alleles conferring ST. Here, we report that allele LEA12 OR , which encodes late embryogenesis abundant (LEA) protein from wild Oryza rufipogon Griff., improves increases under Mechanistically, as early regulator ‐ OsSAPK10 OsbZIP86 OsNCED3 functional module, maintains kinase stability stress, thereby ST promoting abscisic acid biosynthesis accumulation in rice. The superior provides new avenue for improving via application current through molecular breeding genome editing.
