Numerous studies in plants have shown the vital roles of MYB transcription factors in signal transduction, developmental regulation, biotic/abiotic stress responses and secondary metabolism regulation. However, less is known about the functions of in In this study, five medicinal macrofungi of genus were subjected to a genome-wide comparative analysis of genes. A total of 75 genes were identified and classified into four types: 1R-MYBs (52), 2R-MYBs (19), 3R-MYBs (2) and 4R-MYBs (2). Gene structure analysis revealed varying exon numbers (3-14) and intron lengths (7-1058 bp), and noncanonical GC-AG introns were detected in and In a phylogenetic analysis, 69 out of 75 genes were clustered into 15 subgroups, and both single-copy orthologous genes and duplicated genes were identified. The promoters of the genes harbored multiple -elements, and specific genes were co-expressed with the genes, indicating the potential roles of these genes in stress response, development and metabolism. This comprehensive and systematic study of MYB family members provides a reference and solid foundation for further functional analysis of genes in species.
众多针对植物的研究表明,MYB转录因子在信号转导、发育调控、生物/非生物胁迫响应以及次生代谢调控中发挥着至关重要的作用。然而,关于[此处原文缺失具体物种名称]中MYB转录因子的功能,我们所知甚少。在本研究中,对[此处原文缺失具体属名]属的五种药用大型真菌进行了MYB基因的全基因组比较分析。共鉴定出75个MYB基因,并将其分为四种类型:1R-MYBs(52个)、2R-MYBs(19个)、3R-MYBs(2个)和4R-MYBs(2个)。基因结构分析显示外显子数量不同(3 - 14个),内含子长度各异(7 - 1058 bp),并且在[此处原文缺失具体基因名称]和[此处原文缺失具体基因名称]中检测到非典型的GC-AG内含子。在系统发育分析中,75个MYB基因中的69个被聚类到15个亚组中,同时鉴定出了单拷贝直系同源基因和重复基因。MYB基因的启动子含有多个[此处原文缺失具体顺式作用元件名称]元件,并且特定基因与[此处原文缺失具体基因名称]基因共表达,这表明这些MYB基因在胁迫响应、发育和代谢中可能发挥的作用。这项对MYB家族成员全面而系统的研究为进一步分析[此处原文缺失具体物种名称]物种中MYB基因的功能提供了参考和坚实基础。
