Gene Symbol
- Os01g0797600 <=> AP37, OsAP37, OsERF3, OsERF#075, OsERF075, OsERF75, ERF75, AP2/EREBP#004, AP2/EREBP4, OsBIERF2, BIERF2
Function
- OsERF3 (Os01g0797600), is AP2 domain-containing protein, it is found to be significantly up-regulated in both genotypes under cold stress.[1]
- OsERF3 (Os01g0797600) belongs to class II ERFs with a conserved EAR-motif (DLNRPPP) at the C terminal (Nakano et al. 2006). In rice, OsERF3 participated in the resistance to disease and the herbivore-induced defense responses via mediating different hormone pathways (Luet al. 2011).
- OsERF3 is a transcriptional repressor with an ethylene-responsive element-binding factor-associated amphiphilic repression (EAR) motif (F/LDLNxxP), which transcriptionally represses the ethylene emission and drought tolerance in rice. However, its molecular mechanism to explore repression function remains unknown.[2]
- OsERF3, is an AP2 (APETALA 2 Gene)/ERF transcription factor, binds the LRK6 promoter at this new motif, which might cause differential expression of LRK6 in the 93-11/Nipponbare hybrid.The DNA binding ability ofOsERF3’s ERF/AP2 domain was analysed using the one-hybrid assay.[3]
Expression
- The overexpression of AP37 and AP59 in rice under the control of the constitutive promoter OsCc1 increased the tolerance to drought and high salinity at the vegetative stage.
- Increased tolerance to low temperatures was observed only in OsCc1:AP37 plants. More importantly, the OsCc1:AP37 plants showed significantly enhanced drought tolerance in the field, which increased grain yield by 16% to 57% over controls under severe drought conditions, yet exhibited no significant difference under normal growth conditions.
- In contrast, grain yield in OsCc1:AP59 plants in the field was reduced by 23% to 43% compared with controls under both normal and drought stress conditions.
- Microarray experiments identified 10 and 38 genes that are up-regulated by AP37 and AP59, respectively, in addition to 37 genes that are commonly induced by both factors.
