ICLR in S/G2 phase. a–i Yeast cells with indicated gene deletions were synchronized in G1 by α-factor treatment and then released into medium with different concentrations of HN2 for 2 h before plating. The results of three independent experiments + s.d. are shown. Please note that the range of the x-axis in panel b is much smaller than all other panels, due to the extreme sensitivity of these mutants to HN2 treatment
