摘要： In a genome-wide association study, we identified a rice UDP-glycosyltransferase gene, OsUGT706D2 , whose transcription was activated in response to cold and submergence stress and to exogenous abscisic acid (ABA). OsUGT706D2 positively regulated the biosynthesis of tricin-4 0-O-(syringyl alcohol) ether-7-Oglucoside at both the transcriptional and metabolic levels. OsUGT706D2 mediated cold and submergence tolerance by modulating the expression of stress-responsive genes as well as the abscisic acid (ABA) signaling pathway. Gain of function of OsUGT706D2 increased cold and submergence tolerance and loss of function of OsUGT706D2 reduced cold tolerance. ABA positively regulated OsUGT706D2-mediated cold tolerance but reduced submergence tolerance. These findings suggest the potential use of OsUGT706D2 for improving abiotic stress tolerance in rice.
