RPD3, HDA1, and SIR2
influence distinct functional classes. Lists of genes up-regulated at
least 1.5-fold in the rpd3, hda1, and
sir2 (12) profiles are compared in a Venn diagram.
Bioinformatic analysis suggests that RPD3 influences
cell cycle progression, HDA1 influences carbon
metabolite and carbohydrate transport and utilization, and
SIR2 influences amino acid biosynthesis. The number
of genes in the functional class regulated by the deletion/total
number of genes in the functional class are shown in parentheses.
