<i>MoPEX19</i> deletion reduced the conidiation and conidial morphology and viability.

<p>(A) Wild-type, Δ<i>mopex19</i> and complemented strains cultured on CM for 7 days were examined by light microscopy. Bar = 50 μm. (B) Statistical analysis of conidia produced on CM culture at 28°C for 10 days. Means and standard errors were calculated from three independent repeats. Double asterisks indicate significant differences to the wild-type (P<0.01). (C) Normal (I) and nonviable conidia (II) of Δ<i>mopex19</i> under light microscopy. Bar = 10 μm. (D) Viable conidia stained with FDA emitted green fluorescence while the dead ones did not. Bar = 10 μm. (E) Statistical analysis of viability of conidia cultured on CM at 28°C for 10 days. Means and standard errors were calculated from three independent repeats (at least 150 conidia of each strain were measured for each repeat). Double asterisks indicate significant differences to the wild-type (P<0.01).
