摘要：

当前,传统育种手段已经不能完全满足棉花市场及生产的需求,可以利用分子生物技术来加快棉花品种的更新,转录因子为棉花基因功能研究和遗传育种提供了重要的帮助。MYB转录因子家族作为最大的转录因子家族之一,在多种植物中存在,并且在植物的生长发育过程中行使着多种功能。MYB转录因子具有很高的研究价值,在模式植物中的功能已经得到较为深入的研究,但在非模式植物,特别是棉花中的研究仍然较为有限,大多集中在陆地棉中。为进一步了解MYB转录因子,对部分植物及棉花中MYB转录因子的相关研究进展进行了综述,主要涵盖了它们的分类依据、结构特点、进化方式以及在响应生物及非生物胁迫、棉花纤维发育和次生代谢等方面的作用,并对目前已知的棉花MYB转录因子的相关功能进行了分析。通过对这些内容的综述,有助于加深我们对棉花MYB转录因子的了解,为后续研究不同棉种中MYB转录因子以及深入研究它们的功能和机制提供了重要的参考。

Abstract:

Currently,traditional breeding methods cannot fully meet the demands of the cotton market and production. Therefore, molecular biotechnology can be employed to accelerate the development of new cotton varieties. Transcription factors have emerged as significant tools in the study of cotton gene function, genetics, and breeding during this period. Among them, the MYB transcription factor family is one of the largest transcription factor families present in many plants, and it performs multiple roles in plant growth and development. Hence, the MYB transcription factor holds high research value. While the function of MYB transcription factors has been extensively studied in model plants, research in non-model plants, particularly cotton, remains limited and is mostly concentrated in upland cotton. To further understand MYB transcription factors, this paper reviews the research progress on MYB transcription factors in various plants and cotton. It covers their classification basis, structural characteristics, evolution, roles in response to biotic and abiotic stress, cotton fiber development, and secondary metabolism. Additionally, it provides statistics on the known functions of cotton MYB transcription factors. This review aims to deepen our understanding of cotton MYB transcription factors and serve as an important reference for future studies on the functions and mechanisms of MYB transcription factors in different cotton species.

Key words: Cotton, MYB transcription factor, Structure, Function
