From: Quelling targets the rDNA locus and functions in rDNA copy number control
Histone methylation status of the rDNA locus in WT and RNA silencing mutant strains. ChIP analysis using anti-3meH3K9 antibody revealed an enrichment of H3K9 methylation at the rDNA locus compared to non silenced Al-1 locus in WT as well as in quelling defective strains. The error bars represent the standard deviation of two independent IP analyzed by quantitative PCR. Groups of bars labeled * are not statistically different from each other, considering P < 0.05.
