A Phylogenetic tree of R. toruloides Pnt1 and the N. crassa alternative carbon regulatory transcription factors Ara-1, Pdr-1, and Xlr-1. Sequences shown here were assembled from separate BLAST searches for each of these proteins to a database of seven model fungi (see “Methods”). Highlighted proteins have experimentally informed functions discussed in the text. B Phylogenetic tree of RTO4_11990, RTO4_9588, and RTO4_11924 with S. cerevisiae Snf3, N. crassa HGT-1, N. crassa HGT-2 and other homologs from seven model fungi
