摘要:

bHLH(Basic helix-loop-helix)转录因子家族是植物中广泛存在的超基因家族,能结合靶基因启动子上的顺式作用元件,从而广泛参与植物生长发育、次生代谢调控、信号转导和胁迫应答等各种生理生化过程。棉花作为世界上最重要的经济作物之一,枯/黄萎病、低温、高温、盐碱、干旱和重金属等胁迫严重影响棉花产量和纤维品质。同时,随着植棉效益的不断下降,棉籽和次生代谢物等副产品的高值化利用对提高棉花综合利用价值更具有关键意义。本研究对bHLH转录因子在棉花纤维、花药、色素腺体等组织器官发育及体细胞胚胎发生、株型调控、生物/非生物胁迫应答等生命活动中功能的研究进展进行了总结,并对深入解析bHLH转录因子生物学功能,提高棉籽油、棉籽蛋白、棉酚、花青素、棉籽维生素、花蜜等棉花副产品利用价值的应用前景进行了展望,这将为深入阐明bHLH转录因子在棉花生长发育等过程中的功能以及提升棉副产品的综合利用价值提供参考。

Abstract:

bHLH(Basic helix-loop-helix)gene family is one of the largest plant transcription factor families,binds to cis-acting elements on target gene promoters and plays crucial roles in various physiological processes including growth development,secondary metabolism regulation,signal transduction,and stress response.As one of the world's most important cash crops,cotton is severely affected by stresses such as Verticillium and Fusarium wilt,low temperature,high temperature,salinity,drought,and heavy metal exposure,which significantly impact yield and fiber quality.Meanwhile,with the continuous decline in cotton cultivation benefits,the high-value utilization of by-products such as cottonseeds and cotton secondary metabolites plays a crucial role in improving the comprehensive utilization value of cotton.In this paper,the functions of cotton bHLH transcription factors in cotton fiber development,biotic stress response,abiotic stress response,plant architecture,anther,glandular development,and somatic embryogenesis were summarized.Furthermore,it discusses the application prospects of in-depth analysis of the biological functions of bHLH transcription factors in enhancing the utilization value of cotton by-products,such as cottonseed oil,cottonseed protein,gossypol,anthocyanins,cottonseed vitamins,and nectar,in order to provide theoretical reference for further clarifying the functions of bHLH transcription factors in cotton growth and development,as well as improving the comprehensive utilization value of cotton by-products.
