Microscopic observations after GUS and DAB staining of Botrytis cinerea inoculated cv Desiree and DND1 well-silenced potato plants (Scale bar = 100 μm). The same plants were used in the conidia counting in Fig. 2. Samples were taken for GUS and DAB staining at 0.5, 3, 6, and 10 h post inoculation (hpi), respectively. From each genotype, three plants were tested (5 leaflets per plant) and four slides per time point per plant were observed. The photos are representative for the results observed in twelve preparations per genotype
