Evolution of cis-regulatory elements mediating the transcriptional coregulations of box C/D snoRNA and RP genes in eight Ascomycota species. A schematic phylogenetic tree (branches are not drawn to scale) representing the known phylogeny (Kurtzman and Robnett 2003) of the eight analyzed species is shown, together with the schematic cis-regulatory elements mediating the transcriptional coregulation of box C/D snoRNA and RP genes in each species. The total number of box C/D snoRNA or RP genes is given in parenthesis, and the number after each schema represents the number of box C/D snoRNA or RP genes that contain the corresponding motif. One putative binding transcription factor was listed for each motif. Two novel motifs found in Y. lipolytica were named N1 and N2, respectively. Multiple motifs were predicted in C. albicans, and only two motifs were shown. Full annotation of all motifs can be found in Supplemental Table S3.
