Phylogenetic relationships, gene structures and architectures of the conserved protein motifs. A The motif composition of the MsZF-HD proteins. The motifs, numbered 1–10, are displayed in different colored boxes. B Exon-intron structures of the MsZF-HD genes. Yellow boxes indicate untranslated 5′- and 3′-regions; green boxes indicate exons; and black lines indicate introns
