摘要摘 要 ANT (AINTEGUMENTA)类转录因子是植物所特有的一类转录因子，隶属于AP2/EREBP(APETALA2/ethylene-responsive element binding proteins)家族。其家族成员均含有两个由60~70个氨基酸组成的AP2结构域，氨基酸序列仅在AP2结构域处较为保守，其他区域序列存在差异。该家族基因不均匀分布于各物种染色体上，且普遍含有内含子。ANT类转录因子不仅参与调控多种生物学进程, 包括花、果实、根、种子等器官的发育，而且还参与对干旱和盐等环境胁迫的响应。本文对近年来国内外关于ANT类转录因子的蛋白结构特点、基因特征、生物学功能、作用机制等作简要综述，以期为进一步研究和利用ANT类转录因子提供参考。
Abstract：Abstract ANT (AINTEGUMENTA) gene family is a plant-specific transcription factor, which contain two highly conserved AP2 domain. However, the other regions of amino acid sequences were changeable. It is found that ANT genes, belonging to AP2/EREBP(APETALA2/ethylene-responsive element binding proteins)family transcription factors, are involved in the control of organ growth and development and responses to various external environment stressesin plant. This review focused on ANT protein, genetic characteristics, biological function and regulation mechanisms which to provide some references and inspiration for further research of plant ANT like transcription factor.
