The genomic complement of LIM homeobox genes within the four basal metazoans. Ctenophores contain a genomic complement more similar to sponges than to placozoa and cnidarians, which have the full bilaterian complement of LIM homeobox genes. No synteny is found between the LIM homeobox genes in Mnemiopsis. H, Homeobox domain; L, LIM binding domains; LB, LIM binding domain.
