中文摘要：

Abscisic acid-insensitive 4（ABI4）属于APETALA2/ethy lene responsive factor（AP2/ERF）类转录因子,它是在研究ABA信号转导途径中被发现和鉴定的。近年来,ABI4被认为是一种具有多种调节功能的转录因子,它参与了植物种子萌发和幼苗形态建成、质体/线粒体反向信号传递、脂类合成和分解、糖信号和ABA应答等诸多重要的生物学事件。本文综述了ABI4转录因子的结构特征、转录调控模式、基因表达调控和参与的信号转导功能等的最新研究进展。

英文摘要：

Abscisic acid-insensitive 4（ABI4） is a member of APETALA2/ethylene responsive factor（AP2/ERF） family, which was discovered and characterized to be an abscisic acid（ABA） signaling responsive transcription factor. Recent investigations illustrated that ABI4 is a multiple-faced regulatory factor in diverse cellular processes. These biological events include seed germination and seedling establishment, plastid and/or mitochondrial retrograde signaling, lipid metabolism, sugar signaling, and ABA responses etc. This paper summarized the latest research progress of ABI4 in terms of its structure characteristics, transcriptional regulation pattern, gene expression regulation, and signal transduction pathway.
