摘要：SummarySoybean, one of the most valuable oilseed crops, is under constant pressure from pathogens. bZIP transcription factors (TFs) composing one of the largest TF families in plants have diverse functions. Biochemical and physiological analyses were performed to characterize the regulatory roles of soybean bZIP TF GmbZIP15 in response to pathogens. We found that transgenic soybean plants overexpressingGmbZIP15has increased resistance againstSclerotinia sclerotiorumandPhytophthora sojae. Besides,GmbZIP15regulates pathogen response by modulating the antioxidant defense system and phytohormone signaling. In addition, we performed chromatin immunoprecipitation sequencing to identify the downstream genes ofGmbZIP15in response toS.sclerotiorumand found thatGmbZIP15can activate or repress the expression of defense-related genes through direct promoter binding. Taken together, these results indicate thatGmbZIP15plays a positive role in pathogen resistance in soybean, and this activity may be dependent on phytohormone signaling.Graphical abstractDisplay OmittedHighlights•GmbZIP15improves resistance against pathogen•GmbZIP15modulates the antioxidant defense system•GmbZIP15regulates phytohormone signaling•GmbZIP15can direct bind to G-boxEpigenetics; Plant biology; Plant pathology;
