FIG 2.

Essential roles of frq1 and frq2 for the infection cycle of B. bassiana. (A) Images (scale, 10 mm) of mycosis-killed G. mellonella cadavers and fungal outgrowths on the cadavers 9 days postdeath. (B) SEM images (scale bar, 10 μm) for conidiation status of the Δfrq and WT outgrowths on the surfaces of cadavers 9 days postdeath. (C) Conidial yields of fungal strains quantified from cadavers 9 and 12 days postdeath. The cadavers were maintained at 25°C in the indicated L:D cycles. The asterisked yields of the Δfrq1 and Δfrq2 mutants differ significantly from the unmarked yields of their control strains (Tukey’s HSD, P < 0.0001). Each error bar indicates standard deviation of the mean from three replicates of three cadavers per sample.
