Summary: | , an important ancestor species of
, 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
genes in plants has not been comprehensively characterized. In this study, 121 predicted
gene sequences were identified in the rose genome. Additionally, a phylogenomic synteny network (synnet) was applied for the
gene families in 35 complete plant genomes. We also analyzed the
genes regarding their genomic locations, Ka/Ks ratio, encoded conserved motifs, and spatiotemporal expression. Our results indicated that
have multiple synteny clusters. The
gene was included in the Rosaceae-specific Cluster 54, with independent evolutionary patterns. On the basis of these results and an analysis of
-overexpressing tobacco leaf samples, we predicted that
functions in the phenylpropanoid pathway. We clarified the relationship between
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. |
