Loss of histidine biosynthesis trifunctional protein (HIS2, K14152) in complex corals and sea anemones. Syntenic regions surrounding the robust coral K14152 locus are conserved amongst robust corals, complex corals, and sea anemones, but K14152 has been lost in the latter two groups. Gene names identified from a blast search against the SwissProt database are shown at the top of the figure. Gene identifiers from each species are displayed beneath the coloured boxes. Relative positions of syntenic orthologs are aligned, and blank spaces represent missing syntenic orthologs. Red crosses are used to indicate that blast searches (using Evalue threshold 0.1) of those syntenic regions were conducted with both the robust coral K014152 nucleotide and protein sequences but did not detect any homology
