Figure 7. Genome-wide DSB analysis reveals altered Hop1 binding in the absence of CBR-nucleosome interaction directly affects DSB distribution.

Figure 7

(A) CC-sequencing (magenta), with two replicates, is plotted along chromosome XIII as hits per million (HpM) for rad50S and rad50S hop1-loop2 cultures collected at 6 h. Hop1 ChIP signal (blue) is also plotted to compare the relative positions of Hop1 binding and DSB activity. The dotted lines indicate the zoom region plotted to the right of the whole chromosome plot. Black bars represent island regions, black triangles represent centromeres. (B) Meta-analysis of CC-sequencing data comparing read counts associated with hotspots in axis island regions with read counts associated with hotspots in non-axis regions for either rad50S cells or rad50S hop1-loop2 cells. Shaded regions outside of the averages represent 95% confidence intervals. (C) Ratio plots for the average number of DSBs per chromosome in hop1-loop2 rad50S compared to the average number of DSBs per chromosome in rad50S cultures. The chromosomes are organized from smallest to largest. (D) Similar plots as (B), except comparing CC-sequencing data associated in hotspots 20 kb +/− the centromere to CC-sequencing data associated with hotspots outside these regions.
