Growth of wild-type and mutant yeast under different conditions.

<p>The OD₆₀₀ values were measured in a microplate (path length ~0.6 cm). Yeast were grown by flask culture in YP medium (1% yeast extract, 2% peptone) supplemented with 2% glucose (A, B), 3% glycerol (C); and 1% sodium acetate (D), under either normal (A, C, D) or hypoxic (B) conditions. Data are given as the average ± S.E. of three separate cultures. Symbols are: solid circles, wild-type; open circles, Δ<i>fpy1</i>; solid triangles, Δ<i>flx1</i>; open triangles, Δ<i>flx1</i>/Δ<i>fpy1</i>.
