Conservation of known biomineralization genes from stony corals across the Metazoa with fungi as outgroups, based on Figure 1 and Supplementary Table 2 in (Zaquin et al., 2021). Color coding at branches represents presence of the comparably colored genes in taxa within that branch. Not all listed genes are in every branch of that color. Letters at nodes represent mineral types produced by some of the members in branches derived from those nodes as aragonite (A), calcite (C), vaterite (V), gypsum (G), hydroxyapatite (H), and silica (S). Genes found only in one of the coral taxa with a sequenced skeletal proteome (i.e., appear to be novel to that species) are not represented here.
