摘　　要：Salinity-alkalinity is incipient abiotic stress that impairs plant growth and development.Rice(Oryza sativa)is a major food crop greatly affected by soil salinity and alkalinity,requiring tolerant varieties in the saline-alkali prone areas.Understanding the molecular and physiological mechanisms of saline-alkali tolerance paves the base for improving saline-alkali tolerance in rice and leads to progress in breeding.This review illustrated the physiological consequences,and molecular mechanisms especially signaling and function of regulating genes for saline-alkali tolerance in rice plants.We also discussed QTLs regarding saline-alkali tolerance accordingly and ways of deployment for improvement.More efforts are needed to identify and utilize the identified QTLs for saline-alkali tolerance in rice.
