Fig. 2 — Broad taxonomic classification of rhodopsin sequences is indicated and the FcR1 sequence is highlighted with an F. cylindrus icon. Nodes with multiple rhodopsin sequences of the same taxon were collapsed and accessions of the longest sequence are shown together with numbers of collapsed sequences. The tree is rooted in the proteorhodopsin clade for display purposes. Asterisks denote potentially falsely-annotated rhodopsin sequences in the database due to culture contamination. (Credit for F. cylindrus icon to Charlotte Eckmann.).
