Figure 1From: Interactions between cauliflower and Rhizoctonia anastomosis groups with different levels of aggressivenessInitial steps during the infection process of cauliflower with seven R. solani AGs and one binucleate Rhizoctonia AG. A, Microscopic observations of trypan blue stained Rhizoctonia hyphae growing along anticlinal cell walls of cauliflower and branching in T-shaped angles (upper photograph) and formation of infection cushions (lower photograph). Scale bars = 100 ÎĽm. B, Time point (hours post inoculation) of first observation of directed growth of Rhizoctonia hyphae along anticlinal cell walls and formation of T-shaped branches, formation of infection cushions and penetration through stomata.Back to article page
