Phylogenetic tree of 38 M36 family genes used for codon-based maximum likelihood analysis in PAML.

Abstract

<p>Phylogenetic trees were collapsed with inconsistent nodes from different tree-building methods and poor statistical supports into polytomy. Branches <i>a-j</i> indicated putative duplication events in Onygenales fungi. The branches with significant evidence of positive selection are indicated as a thick branch. The putative positively selected residues along these branches were shaded in grey.</p
