Fig. 2.

The phylogeny of CaATL and its BAHD family homologs. The clusters I and II are labeled in the main branches. Numbers above the branches show bootstrap support values from maximum likelihood analysis. The characterized functional proteins from asterids and Arabidopsis are indicated in bold after the species names. The lineage information is indicated after the vertical bars with the branches colored, asterids in orange, fibids in blue, Vitis vinifera in purple, malvids in light green, Caryophyllales in red, the stem eudicotyledons in deep green. The horizontally transferred genes in C. australis from Fabaceae are indicated in brown.
