Figure 6. Effect of medium alkalinization on the conidiation capacity of null gmcA mutant.

Figure 6

A) Conidiation phenotypes after 72 hours of wild-type (TN02A3), ΔflbB (BD177), ΔgmcA (BD429) and the double null ΔflbB;ΔgmcA (BD431) strains grown on MMA supplemented with different concentrations of nitrate (upper block) or ammonium (lower block) as main nitrogen sources. Scale bar  = 2 cm. B) Growth of wild-type and mutant strains on MMA with pH values buffered to 5 (upper line), 7 (middle line) and 9 (lower line) at 96 hours of culture in MMA supplemented with urea as the main nitrogen source. Scale bar  = 1.5 cm. Graphs at the right show conidia production per square centimeter for each strain and growth condition.
