Rad9 is insensitive to meiotic DSBs. Rad9 binding to chromatin adjacent to mitotic HO-induced DSBs (A) and to meiotic programmed DSBs at the HIS4-LEU2 locus (B) was tested by ChIP. Formaldehyde-fixed chromatin extracts were prepared at 0 and 1 h after HO DSB induction in G2/M-arrested cells, and at 0 and 4 h after meiotic induction, followed by anti-HA and anti-Rad51 ChIP. Anti-HA- or anti-Rad51-bound DNAs were quantified by real-time PCR. Error bars represent standard deviations obtained from 3 independent cultures. The non-tagged wild-type and HA-RAD9 strains examined were USY99 and USY100 in (A) and NKY1551 and USY2035 in (B), respectively.
