Figure 7From: Four plant defensins from an indigenous South African Brassicaceae species display divergent activities against two test pathogens despite high sequence similarity in the encoding genesCombined overlay of the light microscopical analysis at 20× magnification and the cell permeabilization assay conducted on B. cinerea grown in the presence of Hc-AFPs for 48 h at 23°C. (A) Control, (B) Hc-AFP1 25 μg ml-1, (C and D) Hc-AFP2 15 μg ml-1, (E) Hc-AFP3 25 μg ml-1, (F) Hc-AFP4 18 μg ml-1. The yellow fluorescence indicates a compromised membrane and the black arrows indicate structures that are leaking their cellular content into the surrounding medium.Back to article page
