摘要
转录因子是一种多功能蛋白,在感知应激信号、应答相应应激基因表达及传导应激信号中起着关键作用。干旱是影响植物生长发育的主要非生物胁迫之一。为了适应干旱环境,植物发展了复杂的分子机制,其中转录因子可同时控制多种途径调控干旱应激,是操纵调控和应激响应途径的有力工具。近年来,越来越多的植物转录因子的功能被阐明,了解转录因子在干旱应激的功能,对植物的工程抗旱有重要的实践意义。综述转录因子在植物干旱应激中的功能研究进展,以期为今后转录因子的研究和利用提供理论依据,培育具有较强抗旱能力的植物。
Transcription factors(TFs)are multi⁃functional proteins that play a significant role in sensing stress sig⁃nals,responding to the expression of corresponding stress genes and transmitting stress signals.Drought is one of the ma⁃jor abiotic stresses that affect plant growth and development.In order to adapt to arid environments,plants have devel⁃oped complex molecular mechanisms in which TFs control multiple pathways simultaneously to regulate drought stress and are powerful tools for manipulating regulatory and stress response pathways.In recent years,the functions of an in⁃creasing number of plant TFs have been elucidated,understanding the function of TFs in drought stress is of important practical significance for the engineering drought resistance of plants.The functional research progress of the TFs in plant drought stress was reviewed,which will provide a theoretical basis for future research on the utilization of TFs and culti⁃vate plants with strong drought resistance.
