Abstract: ERF transcription factors are widespread in plants, which are widely involved in plant response to biotic and abiotic stress. In this study, five novel ERF gene sequences, ERFa/b/c/d/e, were obtained by blast from NCBI data base. Protein sequences analysis showed that the five ERF proteins all contained a typical AP2/ERF binding domain. Phylogenetic analysis indicated that GmERFe was highly homologous to GmERF3 and GmERF7; GmERFb and GmERFc were highly homologous to GmERF5; GmERFd was homologous to GmEREBP1; while GmERFa had lower homology with other ERF proteins. The expression patterns of five ERF genes in soybean tissues and under stress treatments were analyzed by real-time quantitative PCR. The results showed that the five ERF genes expressed highly in root and leaf. GmERFd/e responded mainly to ethylene signal and low temperature, GmERFb responded mainly to drought, and GmERFa responded mainly to low temperature.
