Research progress of AP2/ERF transcription factor family in response to abiotic stress in woody plants

Woody plants constitute fundamental components of global ecosystems, contributing significantly to ecological stability. Throughout their growth, they encounter various abiotic stresses, including cold, drought, salt, and flooding, which can substantially affect their development. The AP2/ERF(APETALA2/ethylene responsive factor)transcription factor family, one of the largest in plants, is widely present in woody species. This review outlines the classification of AP2/ERF transcription factors in woody plants and examines their roles in mediating responses to abiotic stresses, specifically cold, drought, salt, and flooding. Analysis reveals that the ERF and DREB subfamilies predominate within this family in woody plants, with the DREB subfamily member CBF identified as a critical element in cold stress signal transduction. These findings enhance understanding of the functions of AP2/ERF transcription factors in woody plants and their involvement in abiotic stress responses.
