Yta7 regulates histone gene transcription. bar1Δ (solid circles) and yta7Δ bar1Δ (open squares) cells were blocked with α-factor, released, and samples were taken at the indicated times. For each time point, cDNA was prepared and the amount of indicated transcript (relative to ACT1 transcript) was determined by real-time PCR. Darkly shaded regions emphasize the increased histone gene transcription upon gene deletion of YTA7. Error bars are the standard deviation. Asterisks show significant differences determined by one-tailed t-testing (P < 0.05).
