【摘要】 SPL是植物特有的一类转录因子,其蛋白结构中存在一段由2个锌指结构和核定位序列构成的高度保守的SBP结构域,多数SPL基因的转录表达受microRNAs剪切调控。该文结合当前SPLs转录因子的研究进展,对其在植物生长发育和环境适应等方面的生物学功能进行综述,并对SPLs的研究前景进行展望。更多还原

【Abstract】 Squamosa promoter binding protein-like(SPL) family is a class of plant-specific transcription factors, which contain a highly conserved SBP domain consisting of two zinc finger structures and a short nuclear localization sequence.The expression of most SPL genes is regulated by microRNAs at transcription level. Based on the current research progress of SPL transcription factors, this paper summarizes the biological functions of SPLs in plant growth, development,and environmental adaptation, and discusses the future research directions of SPLs.更多还原
