The MYB transcription factor family is one of the largest gene families playing regulatory roles in plant growth and development. The MYB family has been studied in a variety of plant species but has not been reported in Taxus chinensis. Here we identified 72 putative R2R3-MYB genes in T. chinensis using a comprehensive analysis. Sequence features, conversed domains and motifs were characterized. The phylogenetic analysis showed TcMYBs and AtMYBs were clustered into 36 subgroups, of which 24 subgroups included members from T. chinensis and Arabidopsis thaliana, while 12 subgroups were specific to one species. This suggests the conservation and specificity in structure and function of plant R2R3-MYBs. The expression of TcMYBs in various tissues and different ages of xylem were investigated. Additionally, miRNA-mediated posttranscriptional regulation analysis revealed that TcMYBs were the targets of miR858, miR159 and miR828, suggesting the posttranscriptional regulation of MYBs is highly conserved in plants. The results provide a basis for further study the role of TcMYBs in the regulation of secondary metabolites of T. chinensis.

Rosa chinensis, an important ancestor species of Rosa hybrida, the most popular ornamental plant species worldwide, produces flowers with diverse colors and fragrances. The R2R3-MYB transcription factor family controls a wide variety of plant-specific metabolic processes, especially phenylpropanoid metabolism. Despite their importance for the ornamental value of flowers, the evolution of R2R3-MYB genes in plants has not been comprehensively characterized. In this study, 121 predicted R2R3-MYB gene sequences were identified in the rose genome. Additionally, a phylogenomic synteny network (synnet) was applied for the R2R3-MYB gene families in 35 complete plant genomes. We also analyzed the R2R3-MYB genes regarding their genomic locations, Ka/Ks ratio, encoded conserved motifs, and spatiotemporal expression. Our results indicated that R2R3-MYBs have multiple synteny clusters. The RcMYB114a gene was included in the Rosaceae-specific Cluster 54, with independent evolutionary patterns. On the basis of these results and an analysis of RcMYB114a-overexpressing tobacco leaf samples, we predicted that RcMYB114a functions in the phenylpropanoid pathway. We clarified the relationship between R2R3-MYB gene evolution and function from a new perspective. Our study data may be relevant for elucidating the regulation of floral metabolism in roses at the transcript level.
