棉花bHLH转录因子功能研究进展与展望
Research Progress and Prospects on the Function of bHLH Transcription Factor Family in Cotton
摘要
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 impor-tant cash crops,cotton is severely affected by stresses such as Verticillium and Fusarium wilt,low temperature,high tem-perature,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 cot-ton 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 u-tilization value of cotton by-products,such as cottonseed oil,cottonseed protein,gossypol,anthocyanins,cottonseed vita-mins,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.关键词
