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’-O-(syringyl alcohol)ether-7-O-glucoside at both the transcriptional and metabolic ***706D2 mediated cold and submergence tolerance by modulating the expression of stress-responsive genes as well as the abscisic acid(ABA)signaling *** of function of OsUGT706D2 increased cold and submergence tolerance and loss of function of OsUGT706D2 reduced cold *** positively regulated OsUGT706D2-mediated cold tolerance but reduced submergence *** findings suggest the potential use of OsUGT706D2 for improving abiotic stress tolerance in rice.

Multicellular systems rely on the interactions between cells to coordinate cell signaling and regulate cell functions [1]. Understanding the mechanism of cell–cell interactions (CCIs) is critical to many physiological and pathological processes, such as embryogenesis,differentiation, cancer metastasis, and immunological interactions.
