Figure 1.

TCL2 is closely related to TCL1. A. TCL2 is a tandem repeat gene with TCL1 and ETC2 located on chromosome II. B. Phylogenetic analysis of the seven single-repeat R3 MYB transcription factors in Arabidopsis. The phylogenetic tree using the entire amino acid sequence was generated using software CLUSTAL W with default settings ( webcite) C. Sequence alignment of TCL2 and TCL1. Identical amino acids are shaded in same color. Underlines indicate the R3 MYB domain, arrowheads indicate the amino acid signature [D/E]L × 2[R/K] × 3 L × 6 L × 3R that is required for interacting with R/B-like BHLH transcription factors, and asterisks indicate the amino acids within the MYB domain that are crucial for cell-to-cell movement of CPC.
