Fig. 1From: Genomic and transcriptomic survey of bryozoan Hox and ParaHox genes with emphasis on phylactolaemate bryozoansMaximum likelihood phylogeny of Hox and ParaHox genes based on amino acid sequences containing homeodomain and flanking regions of bryozoans and a selection of lophotrochozoan species. ML bootstrap support values are represented by the coloured circles on tree nodes. Clades were collapsed to allow better visibility. Recovered Hox and ParaHox genes in bryozoans are highlighted in grey and their expanded trees are provided in Supplementary Figure S3 -S8. The scale bar indicates amino acid substitutions per site. The homeobox gene Nk1 was used as the outgroupBack to article page
