Disease progressions in N. benthamiana caused by P. cactorum isolate 10300. Leaves (A) or roots (B) were inoculated with a P. cactorum zoospore suspension. (A) Trypan blue-stained leaves at 3, 6, 12 and 24 h post-inoculation (hpi). On each leaf, the left side of the main vein was mock-inoculated with water while the right side was inoculated with zoospores. (B) Plants were inoculated by pouring zoospore suspension around the roots. Upper panel, disease development on whole plants 1, 2, 3, 4, 5 days post-inoculation (dpi). Lower panel, root from plants in upper panel experiments were cut open to observe symptoms inside the roots. Ctrl, roots from control plants mock-inoculated with water.
