The GlcCer synthesis pathway is required for conidiophore development. A total of 105 conidia of WT, ΔsdeA, ΔsmtA, ΔsmtB and ΔgcsA strains were grown in MM + UU + pyro media at 25 °C for 96 h, and mycelia topography was analyzed by SEM. The left, middle and right panels indicate 2,000X, 4,000X and 8,000X magnification, and the bars represent 50, 40 and 20 μm, respectively. Filled white arrowheads show the extracellular matrix, and white arrows and arrowheads highlight reduced and abnormal conidiophores.
