Figure 1From: Amphioxus encodes the largest known family of green fluorescent proteins, which have diversified into distinct functional classesPhylogenetic tree of amphioxus green fluorescent proteins. GFP-like proteins are organized in 6 clades designated a – f. The chromophore region, encompassing the chromophore triplet and the two residues before and after the triplet, is shown in brackets. Representative GFPs from copepods (protostomes) and the anothozoan and hydrozoan cnidarians are also shown. Interspecies bootstraps are all 100%.Back to article page
