Phylogeny of BD-FAE homologs in PULDB. The blue background highlights the monophyletic clade gathering BD-FAE with its homologs predicted in a xylan PULs (leaf label in a bold-blue font; dark = high confidence; light = putative). The green background highlights the monophyletic clade gathering all homologs appearing in an alginate PUL (leaf label in bold-green font)
