Suppression of Δrqh1 HU sensitivity by Δrhp55 is partially dependent on Swi5. We investigated the possibility that Swi5 was necessary for the suppression of the HU sensitivity of Δrqh1 by Δrhp55. (a) Serial dilutions of midlog cultures of wild-type, Δrhp55, Δswi5, Δrhp51, and Δrhp55 Δswi5 cells were plated onto YEA or YEA containing 2.4 mm HU followed by incubation for 5 days. (b) Serial dilutions of midlog cultures of wild-type, Δrqh1, Δswi5, and Δrqh1 Δswi5 cells were plated onto YEA or YEA containing 2.4 mm HU followed by incubation for 5 days. (c) Midlog cultures of wild type, Δrhp55, Δswi5, Δrqh1, Δrqh1 Δrhp55, and Δrqh1 Δrhp55 Δswi5 were plated onto YEA plates containing varying concentrations of HU and incubated for 4–6 days before colonies were counted.
