| Abstract: | Background Ethylene-responsive factors (ERFs) play important roles in plant growth and development and the response to adverse environmental factors, including abiotic and biotic stresses. Results In the present study, we identified 160 soybean ERF genes distributed across 20 chromosomes that could be clustered into eight groups based on phylogenetic relationships. A highly ABA-responsive ERF gene,GmERF75, belonging to Group VII was further characterized. Subcellular localization analysis showed that the GmERF75 protein is localized in the nucleus, and qRT-PCR results showed thatGmERF75is responsive to multiple abiotic stresses and exogenous hormones.GmERF75-overexpressingArabidopsislines showed higher chlorophyll content compared to WT and mutants under osmotic stress. Two independentArabidopsismutations ofAtERF71, a gene homologous toGmERF75, displayed shorter hypocotyls, and overexpression ofGmERF75in these mutants could rescue the short hypocotyl phenotypes. OverexpressingGmERF75in soybean hairy roots improved root growth under exogenous ABA and salt stress. Conclusions These results suggested thatGmERF75is an important plant transcription factor that plays a critical role in enhancing osmotic tolerance in bothArabidopsisand soybean. |
