Detached leaf assay (DLA) of potato RNAi transformants with Botrytis cinerea (strain B05.10). a and b Lesion diameter on the inoculated leaves of the RNAi transformants. a Results from one of the two independent experiments performed for StDMR1, StDMR6 and StPMR4 (two independent well-silenced transformants per gene were used in each experiment); b Results from one of the three independent experiments for StDND1. Four independent transformants were used, one weakly-silenced transformant (−), and three well-silenced transformants (+). Susceptible control was cv Desiree. The average of all lesion diameters per transformant per time point is provided. Asterisks indicate degree of significance compared to cv Desiree plants (*p < 0.05, **p < 0.01, ***p < 0.001); c B. cinerea disease symptoms on cv Desiree and StDND1-silenced transformants. Photos were taken at 3 days post inoculation (dpi)
