棉花纤维发育的分子机理研究进展

Research progress on the molecular mechanism of cotton fiber development

棉纤维不仅是最重要的纺织工业原料,也是研究植物细胞分化、伸长以及细胞壁合成的理想模型。棉纤维细胞的分化和发育受复杂的、相互关联的调控网络所控制。转录因子、功能基因、植物激素、非编码RNA以及表观遗传修饰在棉纤维发育过程中皆起重要的调控作用。随着不同棉花基因组的组装和重测序及关联分析工作的展开,越来越多的调控棉纤维发育的关键因子被挖掘,对进一步解析棉花纤维发育的分子调控机制及助力棉花生物育种具有重要的意义。

Cotton fiber is not only the most important raw material for textile industry, but also an ideal model for studying plant cell differentiation, elongation, and cell wall synthesis. The differentiation and development of cotton fiber is regulated by a complex and interrelated regulatory network. Transcription factors, functional genes, plant hormones, non-coding RNAs, and epigenetic modifications all play important regulatory roles during cotton fiber development. With the assembly, resequencing,and association analysis of different cotton genomes, more and more key factors regulating cotton fiber development have been uncovered, which is of great significance for further elucidating the molecular regulation mechanism of cotton fiber development and helping cotton biological breeding.
