非生物胁迫下转录因子增强植物抗性的研究进展

Advances in Research of Enhancing Plant Resistance by Transcription Factors under Abiotic Stress

转录因子通过调控下游基因的表达来缓冲各种环境压力反应。其中AP2/EREBPL参与植物的细胞周期、生长发育、生物胁迫和非生物胁迫相关的基因的表达调控;MYB参与植物的细胞周期、细胞死亡、新陈代谢等响应;b ZIP基因参与植物种子贮藏相关的基因表达,控制光和发育的发生和器官形态建成等;NAC基因参与了植物激素信号传导和生长素通路。这些转录因子通过调控一系列基因的表达增强植物忍耐逆境胁迫能力。

Transcription factors can response to various forms of environmental stress by regulating downstream gene expression. Among of the transcription factors, AP2/EREBPL involves in plant cell cycle, growth, biological stress and related gene expression regulation under abiology stress. MYB involves in cell cycle, cell death and response metabolism in plant. BZIP are connected with seed storage gene expression, controlling the occurrence of the light and development and the formation organ in plant. NAC genes take in plant hormone signal transduction and auxin pathways. These transcription factors enhance the plant＇stress tolerance ability by regulating the expression of a series of genes.
