摘要
阐述DNA-binding with one finger(Dof)转录因子在作物中应答极端温度、干旱和盐胁迫等逆境的分子机制及其改良农艺性状的作用;介绍Dof转录因子在作物中响应逆境的信号感知方式和信号转导途径,分析其基因表达调控过程的调控机理以及对胁迫耐受力与重要次生代谢产物(RFOs等)等积累的影响。同时从多信号网络调控机制以及全球气候变化对作物可持续和高质量生产的需求角度,对进一步研究和利用Dof转录因子进行作物生物育种的前景和方向作展望。
The molecular mechanisms of DNA-binding with one finger(Dof)transcription factors in crop response to stress such as extreme temperature,drought and salt stress,and their important roles in agronomic trait improvement were analyzed.Combined with the effects of different abiotic stresses on plant growth and development,the signal sensing mode and signal transduction pathway of Dof transcription factors in crop response to stress were introduced.The regulation mechanism of Dof transcription factors and the action mode of stress tolerance and important secondary metabolites(RFOs,etc.)during the regulation of gene expression were analyzed.Moreover,from the perspective of multi-signal network regulation mechanism and the demand of global climate change for sustainable and high-quality crop production,the prospects and directions of further research and utilization of Dof transcription factors in crop bio-breeding were prospected.
