OsERF2 Acts as a Direct Downstream Target of OsEIL1 to Negatively Regulate Salt Tolerance in Rice.

ABSTRACT: Salinity is a significant limiting factor that adversely affects plant growth, distribution and crop yield. Ethylene responsive factors play crucial roles in plant responses to and tolerance of various abiotic stresses. Recently, we revealed that OsERF2 is involved in root growth by transcriptionally regulating hormone and sugar signaling in rice. Here, we report that OsERF2 is a direct target gene of OsEIL1 and negatively regulates salt tolerance in rice. Compared to the wild type, the gain-of-function mutant of OsERF2 (nsf2857) and the knockdown of OsERF2 via an artificial microRNA (Ami-ERF2) exhibited decreased and increased salt tolerance, respectively. The enhanced salt tolerance observed in Ami-OsERF2 lines was associated with lower accumulations of malondialdehyde and reactive oxyge
