Fig. 5

Heatmap of algae selenoprotein distribution. The selenoprotein families and organisms were clustered based on the existence of selenoproteins or different types of homologies. The cluster trees are shown on the top and left side of the heatmap. In the organism cluster tree, the green/red branches indicate high−/low-level selenium algae, which is also shown in Fig. 1. The colored cells with different shades in the heatmap indicate the existence of the different types of selenoproteins or homologies. The meaning of the colors is shown in the top-left corner square. For example, “dark green”, labeled with “Sec” indicates the exclusive existence of selenoprotein; “light green”, labeled with “Sec & Cys”, indicates that selenoprotein and Cys-containing homology were both identified; “gray”, labeled with “other”, indicates the exclusive existence of homologs containing neither Sec nor Cys. The taxonomic description of algae, such as Plante, SAR group, Diatoms, Red algae, etc., is shown beside the organism names with different color backgrounds. On the bottom, the selenoproteome size, genomic size, gene numbers, and living environments of each organism are shown in order. In the chart of “selenoproteome size”, the length of the whole column (composed of green and gray areas) represents the total number of protein families (including selenoproteins and other homologies) of each species. The length of the green bar indicates the number of selenoprotein families. Additionally, the red bar inside the column indicates the number of genomic flanking region duplications found in a specific organism
