StMKK1 positively regulates potato resistance to Botrytis cinerea. Representative leaf images of StMKK1 overexpression transgenic lines before (a) and after (b) trypan blue staining showing lesions of B. cinerea at 2 dai. c Bar graph showing that overexpression of StMKK1 in potato significantly reduces B. cinerea lesion areas compared to that in the wild-type Desiree. Representative leaf images of StMKK1 RNAi transgenic lines before (d) and after (e) trypan blue staining showing B. cinerea lesions developed at 2 dai. f Bar graph showing that silencing of StMKK1 in potato significantly increases B. cinerea lesion areas compared to that in Desiree. All leaves were infected with B. cinerea B05.10. Each inoculation test was repeated three times with similar results. In (c) and (f), error bars show the standard deviations from 16 replicates, two-sided t-tests were used to assess significance: *, p < 0.05, **, p < 0.01
