Asexual spore production and growth in
rdrp-2Δ mutants. A. Asexual spores produced by wild-type strain (R7B) and the indicated mutants grown in the dark (blue bars) or in the light (red bars) for 72 h in solid MMC medium pH 3.2. B. Asexual spores produced by wild-type strain (R7B) and rdrp-1Δ and rdrp-2Δ mutants grown in the same conditions, except that solid YNB medium was used instead of MMC. The values are means and standard errors of 10 independent measurements. C. Radial growth of RNAi mutants at pH 2.25. A drop (5 μL) with 1000 spores of the indicated strains was deposited at the center of a Petri dish with solid complete medium (YPG) at pH 2.25. The radial growth was monitored periodically by measuring colony diameter. Averages and standard errors from five colonies per strain are shown.
