木质细胞发育出次生壁结构，主要由多糖（纤维素和半纤维素）和木质素组成。这些成分有望成为生物燃料和生物材料的新来源。因此，了解次生壁形成的分子机制及其对植物生物量的贡献是非常重要的。植物特异性NAC结构域转录因子家族具有多种生物学功能。最近，一些研究报道NAC结构域转录因子的一个亚家族在次生壁形成中起关键作用。本文就NAC结构域转录因子在调控次生壁形成中的作用作一综述。
Woody cells develop secondary wall structure that mainly consists of polysaccharides (cellulose and hemicellulose) and lignin. These components are expected to be new sources of biofuels and biomaterials. Therefore, it is important to understand the molecular mechanism underlying secondary wall formation and how it contributes to plant biomass. Plant-specific NAC domain transcription factor family has been shown to be involved in diverse biological functions. Recently, several studies reported that a subfamily of the NAC domain transcription factors plays pivotal roles in secondary wall formation. In this review, we have summarized the role of NAC domain transcription factors in controlling the secondary wall formation.
