植物NAC转录因子家族研究概况

A Survey of Functional Studies of the Plant-specific NAC Tran-scription Factor Family

植物特有的NAC家族转录因子数量众多,广泛分布于陆生植物中。NAC转录因子涉及多个生长发育和胁迫应答过程,功能多样而重要,从发现至今一直是研究的热点。ANAC019蛋白三维结构的解析和一系列NAC基因功能的揭示可以帮助我们更全面地了解NAC家族,包括它们的起源与分类、生物学功能、表达调控规律以及结构与功能的关系。该文较为详尽地阐述了NAC家族转录因子的研究现状,并展望其未来的研究方向。

The plant-specific NAC transcription-factor family has numerous members widely distributed in many land plant species. NAC genes play diverse and vital roles in various plant-growth and developmental processes and stress responses. Until now, efforts have been devoted to characterization and functional analysis of NAC genes. Recently, the tertiary structure of the NAC domain of ANAC019 protein has been revealed, and the function and characterization of a series of NAC genes was illuminated. Understanding the roles of NAC family genes has improved in various aspects, including their origin and classification, biological functions, regulation of expression and relationship between structure and function. This review summarizes the latest research advances in understanding NAC genes and offers suggestions for further research.
