Characterization of the R2R3-MYB Transcription Factor CsMYB113 Regulates Anthocyanin Biosynthesis in Tea Plants (Camellia sinensis)

Tea plant (Camellia sinensis) has very long history of cultivation and abundant germplasm resources in China. Purple bud is a characteristic variety, which attracted the attention breeding researchers because it accumulated large number anthocyanins naturally. In many species, R2R3-MYB transcription factors (TFs) were proved to be involved regulation anthocyanin biosynthesis. Research on metabolism been relatively clear some but that needs further elucidated tea plants. this research, an factor CsMYB113 related accumulation was identified from Spatial temporal expression analysis revealed differential among different tissues organs, with highest occurring roots. Subcellular localization assays showed localized nucleus. Ectopic increased pigmentation contents by upregulation levels genes biosynthesis pathway Arabidopsis. Moreover, transient overexpression 35S::CsMYB113 leaves. Our results indicated plays important role It will also provide useful candidate gene for modification genetic engineering
