Sugar transporters subjected to phylogenetic classification. The tree was inferred using 335 protein sequences from T. reesei, A. niger, A. nidulans and N. crassa containing the Pfam PF00083 domain. The sugar transporters characterized experimentally in the literature [42] are highlighted with bold font and the transporters identified in this study are highlighted in red and bold. Each clade potential substrates are determined based on the functions of known sugar transporter members within those specific clades. Three clades in red did not resemble experimentally characterized sugar transporters. Support values from 1000 resamples are illustrated as gray dots
