Dissecting the Genome-Wide Evolution and Function of R2R3-MYB Transcription Factor Family in Rosa chinensis

“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.”
