Hyperosmotic stress-triggered delay in mitotic progression is partly mediated by PHS1. (a) Microscopic cell images of three genotypes (wild type, phs1 mutant, a complementation line) after 0.3 M sorbitol treatment at 9 h of culture. Arrows indicate clusters of newly divided daughter cells. (b) Cell growth and formation of daughter cell clusters. Sorbitol at 0.3 M was applied at 9 h after the start of culture (during the period indicated by a black bar). ***; statistically significant difference at p < 0.01 by one-way ANOVA with Tukey-HSD post-hoc test, when compared with wild-type values. Error bars indicate standard deviations from five biological replicates
