Growth phenotypes of GR5 (wild type) and IM69 (ΔatmA). (A) The strains were grown for 72 hr at 37° in YG medium in the presence or absence of 4-NQO, BLEO, hydroxyurea (HU), MMS, and CPT. (B) Quiescent (left) and germinating (right) conidiospores from different strains were exposed to UV light, and viability was scored after exposure as the percentage of colonies on treated plates compared to untreated controls. To evaluate the differences in UV-light assays, we used one-way ANOVA and Student Newman Keuls posthoc test (Daniel 2005). The results were expressed by the average of four independent experiments and the means plus the standard deviation are shown. Analyses were performed using the software package Sigma Stat (Jandel Scientific, San Rafael, CA) and the statistical significance was set at a = 0.05.
