The large Rpd3 complex and its targets are required for DAN1 expression. Yeast strains were grown aerobically and shifted to anaerobic growth. (A) Northern blots for wild-type (WT), sap30Δ, sin3Δ, and rpd3Δ strains. (B) Northern blots for wild-type, swi3Δ, swi10Δ, snf2Δ, and snf6Δ strains. (C) Northern blots for wild-type and rpd3Δ strains and strains with N-terminal deletions of histones H4 (hhf1Δ2-26) and H3 (hht1Δ1-28).
