Plants, being immobile, are subject to environmental stresses more than other creatures, necessitating highly effective stress tolerance systems. Transcription factors (TFs) play a crucial role in the adaptation mechanism as they can be activated by diverse signals and ultimately control the expression of stress-responsive genes. One of the most prominent plant TFs family is MYB (myeloblastosis), which is involved in secondary metabolites, developmental mechanisms, biological processes, cellular architecture, metabolic pathways, and stress responses. Extensive research has been conducted on the involvement of MYB TFs in crops, while their role in cotton remains largely unexplored. We also utilized genome-wide data to discover potential 440 MYB genes and investigated their plausible roles in abiotic and biotic stress conditions, as well as in different tissues across diverse transcriptome databases. This review primarily summarized the structure and classification of MYB TFs biotic and abiotic stress tolerance and their role in secondary metabolism in different crops, especially in cotton. However, it intends to identify gaps in current knowledge and emphasize the need for further research to enhance our understanding of MYB roles in plants.
植物是固定不动的,比其他生物更容易受到环境压力的影响,因此需要高度有效的应激耐受系统。转录因子(TFs)在适应机制中起着至关重要的作用,因为它们可以被各种信号激活,最终控制应激响应基因的表达。MYB(髓样细胞瘤)是植物 TF 家族中最著名的一个,它参与次生代谢、发育机制、生物过程、细胞结构、代谢途径和应激反应。人们对 MYB TFs 在作物中的作用进行了广泛的研究,但它们在棉花中的作用在很大程度上仍未被探索。我们还利用全基因组数据发现了 440 个潜在的 MYB 基因,并研究了它们在非生物和生物胁迫条件下,以及在不同转录组数据库中的不同组织中的可能作用。本综述主要总结了 MYB TFs 在生物和非生物胁迫耐受性以及在不同作物,特别是棉花中的次生代谢中的结构和分类。然而,它旨在确定当前知识中的差距,并强调需要进一步研究,以增强我们对 MYB 在植物中的作用的理解。
