Abiotic stress is a crucial factor that affects plant survival and growth and even leads to plant death in severe cases. Transcription factors can enhance the ability of plants to fight against various stresses by controlling the expression of downstream genes. The dehydration response element binding protein (DREB) is the most extensive subfamily of AP2/ERF transcription factors involved in abiotic stress. However, insufficient research on the signal network of DREB transcription factors has limited plant growth and reproduction. Furthermore, field planting of DREB transcription factors and their roles under multiple stress also require extensive research. Previous reports on DREB transcription factors have focused on the regulation of DREB expression and its roles in plant abiotic stress. In recent years, there has been new progress in DREB transcription factors. Here, the structure and classification, evolution and regulation, role in abiotic stress, and application in crops of DREB transcription factors were reviewed. And this paper highlighted the evolution of DREB1/CBF, as well as the regulation of DREB transcription factors under the participation of plant hormone signals and the roles of subgroups in abiotic stress. In the future, it will lay a solid foundation for further study of DREB transcription factors and pave the way for the cultivation of resistant plants.
非生物胁迫是影响植物生存和生长的关键因素，在严重情况下甚至会导致植物死亡。转录因子可以通过控制下游基因的表达来增强植物对抗各种胁迫的能力。干旱应答元件结合蛋白（DREB）是参与非生物胁迫的 AP2/ERF 转录因子中最广泛的亚家族。然而，对 DREB 转录因子信号网络的研究不足限制了植物的生长和繁殖。此外，DREB 转录因子在田间种植及其在多种胁迫下的作用也需要广泛研究。以前关于 DREB 转录因子的研究主要集中在 DREB 表达的调控及其在植物非生物胁迫中的作用。近年来，DREB 转录因子取得了新的进展。本文综述了 DREB 转录因子的结构和分类、进化和调控、在非生物胁迫中的作用以及在作物中的应用，并强调了 DREB1/CBF 的进化以及植物激素信号参与下 DREB 转录因子的调控和亚组在非生物胁迫中的作用。为进一步研究 DREB 转录因子奠定了坚实的基础，为培育抗性植物铺平了道路。
