Fig. 6.

ML-tree for CAD-DFR enzymes. Phylogeny was obtained starting from 722 CAD and 109 DFR protein sequences. Thicker clades indicate node support >75%. At the end of leaves, dark and light blue colors differentiate DFR and CAD sequences, respectively. Red bars and green, cyan and magenta boxes represent motifs retrieved by MEME analysis of algal sequences within the respective domains IPR002328 and IPR001509. Algal divisions are indicated as color arches, following the legend presented in Fig. 2. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
