摘　　要：木本植物是全球生态系统的重要支柱,在维护生态平衡中起着重要作用,其在生长过程中会受到多种非生物胁迫,如冷胁迫、干旱胁迫、盐胁迫等,这些胁迫会严重影响木本植物的生长发育。AP2/ERF(APETALA2/ethylene responsive factor)转录因子在木本植物中分布广泛,是植物最大的转录因子家族之一。文章总结了木本植物AP2/ERF转录因子的分类情况,探讨了AP2/ERF转录因子在木本植物响应非生物胁迫(冷、干旱、盐、淹水)中的关键作用。研究还发现,木本植物AP2/ERF转录因子家族中ERF和DREB亚家族成员数量最多,其中DREB亚家族成员CBF是木本植物冷胁迫信号转导的关键因子。该综述为更好地理解木本植物中AP2/ERF转录因子的功能及其在非生物响应中的作用提供了支撑。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.
