Fig 2. Strains with hyperpolarized membranes are less tolerant to LiCl and cationic drugs.

Fig 2

(A) Relative membrane potential of BY4741 (black circles), erg2Δ (red squares), erg3Δ (green triangles), erg4Δ (yellow triangles), erg5Δ (blue diamonds) and erg6Δ (cyan hexagons) cells estimated with diS-C3(3) fluorescence probe. (B) Relative growth in liquid YPD medium supplemented with 100 mM LiCl (growth in YPD medium without LiCl = 100%). The P values (*P < 0.05, **P < 0.001) denote statistically significant differences from the wild-type strain. (C) Growth on solid YPD media supplemented with LiCl, hygromycin B and tetramethylammonium (TMA) after 1 day of incubation.
