Epimedium sagittatum (Sieb. et Zucc.) Maxim, a popular traditional Chinese medicinal plant, has been widely used for treating sexual dysfunction and osteoporosis in China. The main bioactive components in herba epimedii are prenylated flavonol glycosides, which are end products of a branch of the flavonoid biosynthetic pathway. The MYB transcription factors (TF) act as activators or repressors to regulate the flavonoid pathway. In this study, 13 full-length cDNA clones of R2R3-MYB TFs from E. sagittatum (designated as EsMYB1 to EsMYB13) were isolated and characterized. Sequence similarity and phylogenetic analysis placed nine R2R3-MYB members of E. sagittatum into five subgroups of the Arabidopsis R2R3-MYB family, while four members were not clustered into a defined subgroup. The number and length of introns from Epimedium R2R3-MYB genes varied significantly, but intron positions and phases were well conserved. Expression patterns of Epimedium R2R3-MYB genes in various tissues showed diverse. Finally, it is suggested that five Epimedium R2R3-MYB genes may be involved in regulating the flavonoid pathway and could be used as valuable candidate genes for metabolic engineering studies in future. Sequence information of 13 R2R3-MYB genes discovered here will also provide an entry point into the overview of whole R2R3-MYB family in Epimedium.
