摘要
NAC(NAM、ATAF1、ATAF2和CUC2)转录因子是植物特有的一类转录因子,在多种陆生植物基因组中发现有超过100个成员,是植物基因组中最大的转录因子家族之一。该家族转录因子的共同特点是其N端具有保守的NAC结构域,C端则为高度变异和具有转录激活功能的调控区。具有多种生物功能NAC家族转录因子在植物生长发育、胁迫应答和激素调节等过程中具有重要作用。就植物NAC转录因子的基本结构特征和生物学功能最新研究进展进行综述。
NAC （ NAM, ATAF1, ATAF2 and CUC2 ） family proteins are plant-specific transcription factors which constitute one of the largest families. The family is present in a wide range of land plants with more than a hundred members in plant genomes. The NAC genes contains a general structure that consists of a highly conserved NAC domain at the N-terminus and a variable C-terminal functions as the activation domain. NAC transcription factors play important roles in multiple biological processes such as plant development, response to stresses and hormone signals. This article provide an overview of the basic structure, biological function and current status of plant NAC transcription factors.
