花生非生物胁迫响应转录因子研究进展

Research advances on abiotic stress response transcription factors in peanut

花生生育期易遭受干旱、低温、高盐等非生物胁迫,影响其出苗、开花、营养物质积累等过程,从而造成花生产量和品质的下降。在作物遭受非生物胁迫时,通过转录因子调控下游功能基因的表达,是植物应对胁迫的一种重要调控模式。本文对非生物胁迫相关的转录因子NAC、AP2/ERF、bZIP、MYB等基因家族的结构、功能及相关基因在花生抗逆反应中的研究进展进行了综述,为花生抗逆分子育种提供参考。

Abiotic stresses such as drought, salt and cold may affect a series of growth processes such as germination, flowering, dry matter accumulation and fruiting, and ultimately affect yield and quality of peanut. When crops are subjected to abiotic stress, the regulation of downstream functional genes by transcription factors is an important regulation mode for plants to cope with stress. The research progress of the structure, function and stress resistance responses of abiotic stress-related transcription factors NAC, AP2/ERF, bZIP, MYB were reviewed.
