Phylogenetic relationships among the (putative) fungal FAEs. Glucuronoyl esterases (GEs, green-filled circles) were used as an outgroup. AXE, acetyl xylan esterase (blue-filled circles); LIP, lipase (yellow-filled squares); SF, subfamily; TAN, tannase (purple-filled circles). FAEs from previously reported phylogenetic analysis [51] were marked with magenta open triangles for SF1, magenta open rhombuses for SF2-4, magenta-filled triangles for SF5, magenta-filled rhombuses for SF6, light blue-filled squares for SF7, brown-filled circles for AtFAE2 and AtFAE3, and magenta-filled circles for ungrouped ones. Light blue-filled circles indicate ungrouped sequences which numbering indicates different groups
