摘要
DELLA蛋白作为GA信号转导通路中起抑制作用的转录因子,是一类定位在核内的生长抑制蛋白,可以直接与植物体内关键转录因子的蛋白互作,进而在许多植物信号活动中发挥核心作用。该文对近年来国内外有关模式植物及果树、蔬菜、花卉、粮食作物等植物DELLA蛋白基因家族的鉴定、时空表达模式、蛋白结构、参与的GA信号转导机理、与光敏色素互作因子PIF及F-box蛋白的互作及DELLA蛋白在植物种子萌发、形态建成、豆科植物根瘤菌共生、气孔关闭、植物抗逆反应等过程中的重要作用等方面的研究进展进行综述,并比较了DELLA蛋白基因家族在不同物种中的差异,对其今后的研究热点和方向进行了展望,为进一步探讨DELLA蛋白的功能提供信息。
DELLA protein,a transcription factor that plays an inhibitory role in the GA signal transduction pathway,is a type of growth inhibitory protein that localized in the nucleus and can directly interact with proteins of key transcription factors in plants,thereby playing a central role in many plant signaling activities.This paper summarizes the identification,temporal and spatial expression patterns,molecular structure,regulatory mechanisms in GA signal transduction,interaction with PIF and F-box protein of DELLA protein gene family and the role of DELLA protein in seed germination,morphogenesis,rhizobial symbiosis of legumes,stomatal closure,plant stress response and so forth of several fruit trees,vegetables,flowers,model plants,grain crops,and so forth at home and abroad in recent years,and the difference of DELLA protein gene family between these species are also compared.Finally,we prospected its future research hotspots and directions,to provide information for further exploration of the function of DELLA protein.
