Genome-Wide Characterization and Comparative Analysis of MYB Transcription Factors in Species.

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.
