Comparative carbon source utilization profiles of the Δ<i>ste12</i> and Δ<i>tmk1</i> mutants and the parental strain (WT).

<p>Strains were grown on 95 carbon sources (FF-plates) using the Biolog Phenotype Microarray system. Hierarchical clustering results are displayed as coloured mosaics attached to a dendrogram according to growth (OD₇₅₀) after 48 hours of incubation. All data points are the average of three replicates. The threshold cut-off for all conditions was set at 0.225 which corresponded to growth of the parental strain on the water control. Red boxes indicate maximal growth (OD₇₅₀ 0.7–1.3), black boxes medium growth (OD₇₅₀ 0.55–0.7), and green boxes weak growth (OD₇₅₀ 0.2–0.55).
