The adverse effects of climate change on crop production are constraining breeders to develop high-quality environmentally stable varieties. Hence, efforts being made identify key genes that could be targeted for enhancing tolerance environmental stresses. ERF transcription factors play an important role in various abiotic stresses plants. However, the roles family still largely unknown sesame, "queen" oilseed crops.In total, 114 sesame (SiERFs) were identified and characterized. 96.49% SiERFs distributed unevenly 16 linkage groups genome. phylogenetic analysis with Arabidopsis ERFs (AtERFs) subdivided SiERF subfamily proteins into 11 subgroups (Groups I X; VI-L). Genes same subgroup exhibited similar structure conserved motifs. Evolutionary showed expansion was mainly induced by whole-genome duplication events. Moreover, cis-acting elements mostly involved responses. Gene expression profiles revealed 59 26 highly stimulated under drought waterlogging stress, respectively. In addition, qRT-PCR analyses indicated most also significantly up-regulated osmotic, submerge, ABA, ACC Among them, SiERF23 SiERF54 both stresses, suggesting their potential improvement response multiple stresses.This study provides a comprehensive understanding structure, classification, evolution, sesame. it offers valuable gene resources functional characterization towards
