Conidiation morphology of QM 6a and the pks4 deletion mutants. (a) Plate macromorphology and conidial pigmentation of QM 6a and Δpks4 cultures. (b) Conidial pigmentation of QM 6a and Δpks4 mutants on selected carbon sources of the Biolog FF microplate phenotype microarrays. (c) Conidial density of QM 6a and Δpks4 mutants' spores produced after 7 days of cultivation PDA. No statistically significant difference in the intensity of conidia production was observed (ANOVA, P > 0.05). (d) Conidial mechanical stability observed under a FEI Quanta 200 FEGSEM after application of vacuum conditions and high pressure, under 25,000× magnification.
