High iron mediated flocculation was absent in Δ hog1 and Δ pbs2 mutants. (A) Microscopic analysis of DAY286, Δhog1 (JMR114) and Δpbs2 (JJH31) upon exposure to iron. (B) Relative sedimentation rates of the reference strain (DAY286) and of Δhog1 (JMR114) and Δpbs2 (JJH31) mutants incubated in RPMI containing 30 μM FeCl3 or water (control) at 30°C for 2 h. Means and standard deviations of three independent samples are shown (n = 3). *** denotes P < 0.001 (student’s t-test). (C) Relative sedimentation rates of the WT (SC5314), Δhog1 (CNC13) and Δhog1 + HOG1 (hAHGI) incubated in RPMI containing 30 μM FeCl3 or water (control) at 30°C for 2 h. The hAHGI strain carries the HOG1 gene fused to GFP under control of the ACT1 promoter and integrated in the LEU2 locus [31]. Means and standard deviations of three independent samples are shown (n = 3). *** denotes P < 0.001 (student’s t-test).
