植物中 Trihelix 转录因子的共同特征是 DNA 结合域含有 3 个连续的α -螺旋。该家族最早被发现能与光应答元件GT 元件特异性结合,所以该家族也被称为 GT 因子家族。最新研究表明 Trihelix 转录因子家族不仅参与光反应应答,还广泛地参与植物对生物和非生物胁迫的应答。本研究主要介绍了植物 Trihelix 转录因子结构特征、家族分类,以特殊耐盐种质资源甜菜 M14 品系中 Trihelix 转录因子 GT-1 亚家族响应盐胁迫基因表达模式的分析为例,结合最新的研究进展,重点阐述了Trihelix 转录因子与环境相互作用的功能。为今后深入探索 Trihelix 转录因子参与植物光响应、生物及非生物胁迫等方面的分子机理奠定良好的基础。
Plant Trihelix transcription factors (TFs) generally exhibit three continuous alpha-helixes within the DNA binding domain. Since these TFs were first found to specifically bind with GT elements, this family was also referred the GT factor family. Recent achievements showed that Trihelix transcription factors were involved in light response, and also various types of biotic and abiotic stresses. Here the structural characteristics and family classification of plant Trihelix transcription factors were summarized. As example of the gene expression patterns of GT-1 subfamily in sugar beet and the latest research progress, we reviewed the interactions between Trihelix transcription factor and environmental factors. This will lay a foundation for further exploring the molecular mechanism of Trihelix transcription factors being involved in plant light response as well as biotic and abiotic stresses.
