摘要
B3类转录因子基因组成了植物所特有的B3基因超家族,按照其结构和功能的特征可将其进一步分为LAV(LEAFY COTYLEDON2[LEC2]–ABSCISIC ACID INSENSITIVE3[ABI3]–VAL)、ARF(AUXINRESPONSE FACTOR)、RAV(RELATED TO ABI3 and VP1)和REM(REPRODUCTIVE MERISTEM)等4个家族。B3基因超家族主要存在于裸子植物、苔藓和绿藻类植物中,并在植物逆境胁迫响应和生长发育过程中起着极其重要的作用。目前已在拟南芥中发现了118个B3类转录因子,本文综述了拟南芥中B3转录因子基因超家族的系统发育和功能鉴定方面的研究进展。
The B3 transcription factor genes form a plant-specific B3 gene superfamily and can be further classified into four families: LAV (LEAFY COTYLEDON2 [LEC2]-ABSCISIC ACID INSENSITIVE3 [ABI3]-VAL), ARF (AUXIN RESPONSE FACTOR), RAV (RELATED TO ABI3 and VP1) and REM (REPRODUCTIVE MERISTEM) family. The B3 transcription factor genes exist mainly in gymnosperms, mosses and green algae and play extremely important roles in plant stress responses and plant growth and development. In Arabidopsis, 118 B3 superfamily transcription factor genes have been identified. This review aims to overview the research progress of the phylogenetical and functional characterization of the B3 gene superfamily in Arabidopsis.
