Transcriptomic analysis revealed that GmERF1 expression is induced by Phytophthora sojae and positively regulates soybean resistance to P. sojae via salicylic acid signal transduction pathway.

Abstract

Soybean (Glycine max) root rot caused by Phytophthora sojae is a major disease constraining the global soybean industry. Therefore, improving crop resistance to this pathogen remains a key objective in breeding efforts. However, the mechanisms by which soybeans respond to P. sojae infection, as well as the specific regulatory networks of key transcription factors (TFs), remain to be elucidated. Here, we report that Ethylene Response Factor 1 (GmERF1), encoding an AP2/ERF transcription factor, exhibits significant differences in expression between resistant and susceptible soybean cultivars. Molecular evaluation and disease resistance analysis show that GmERF1 could improve soybean resistance to P. sojae. Further transcriptomic analysis and quantitative analysis of salicylic acid (SA) signal transduction genes indicate that GmERF1 could positively regulate the expression of Non-expressor of Pathogenesis-Related genes 1 (GmNPR1), TGACG sequence-specific binding factor (GmTGA) and Pathogenesis-Related gene 1 (GmPR1). Taken together, these results suggest that GmERF1 positively regulates soybean resistance to P. sojae by enhancing SA signaling, providing novel insights into soybean resistance to Phytophthora root rot.
