Phylogenetic tree of Rel homology domain (RHD)-containing proteins in the 1st set of candidate genes of tardigrades and non-arthropod ecdysozoans, together with Dif, Dorsal, Relish, and NFAT orthologs of poriferans, cnidarians, arthropods, mollusks, annelids, echinoderms, and chordates. The tree was built using the VT+G+I model with 1000 bootstrap replicates and midpoint rooted. Branch colors represent different phyla. Complete bootstrap values available in Figure S2. Scale bar = number of nucleotide substitution/site.
