Δ<i>gmcA</i> null mutant under different stress conditions or carbon sources.

<p>A) Colony and conidiation phenotypes of wild type (TN02A3), Δ<i>flbB</i> (BD177), Δ<i>gmcA</i> (BD429) and double null (Δ<i>flbB</i>;Δ<i>gmcA</i>; BD431) cultured on standard nitrate (80 mM) MMA alone or supplemented with H₂PO₄ (0.5 M), sucrose (1 M) or hydrogen peroxide (6 mM) after 72 hours of culture. Scale bar = 2 cm. B) Colonial growth of the same strains in standard nitrate (80 mM) MMA supplemented with different concentrations of glucose (0.5 and 5% w/v) or glycerol (1 and 10%) as carbon sources after 72 hours of culture. Scale bar = 2 cm. Graphs at the right side show conidia production per square centimeter for each strain and growth condition.
