AP2/ERF蛋白调控植物的非生物胁迫应答机制

Mechanism of Plant Response to Abiotic Stresses Regulated by AP2/ERF Proteins

AP2/ERF蛋白是植物所特有的转录因子,参与植物生长发育以及调控生物和非生物胁迫反应。研究表明,AP2/ERF蛋白不仅与其它类型转录因子共同形成复杂的转录调控网络,通过多种信号转导途径调控功能基因的表达,而且可以作为外界信号的感应因子调控植物的非生物胁迫应答。主要从AP2/ERF蛋白在植物激素合成、蜡质合成、低氧胁迫应答、ROS清除以及蛋白质修饰等方面综述了AP2/ERF蛋白在植物非生物胁迫应答中的研究进展,并展望了今后的研究方向。

The AP2/ERF proteins, one family of plant-specific transcription factors, invole in plant growth and development, and regulate plant resistance to biotic and abiotic stresses. Studies have shown that AP2/ERF proteins could not only form a complex transcriptional regulatory network with other types of transcription factors to regulate the expression of functional genes through multiple signal transduction pathways, but also regulate plant abiotic stresses as sensing factor of external signal. This paper reviews the progress on studying AP2/ERF proteins in response to abiotic stress, including plant hormone synthesis, wax synthesis, hypoxia stress response, ROS scavenging and protein modification, etc. , and prospects the research orientations in the future.
