Figure 3. Identification of putative transcriptional regulators involved in anthocyanin biosynthesis in tea.

Schematic representation of the phylogenetic relationships existing between the tea MYB (A), basic helix–loop–helix (bHLH) (B) and TTG1-like (C) proteins isolated and used in this study with their closest homologues. Sequences were aligned using Clustal X and phylogeny reconstruction was done using the neighbour-joining method and tested using the bootstrap method with 1000 replicates. Both alignment and phylogenetic analysis were performed using MEGA version 7.
