Figure 3From: Calcium-mediated perception and defense responses activated in plant cells by metabolite mixtures secreted by the biocontrol fungus Trichoderma atrovirideDetection of intracellular ROS accumulation in soybean cells treated with fungal culture filtrates. Intracellular ROS were detected by H2DCF-DA staining in control cells (Co, a'), in cells treated with >3 kDa (b'-e') and <3 kDa (f'-i') fractions of wild type Trichoderma (wt Tr, b'and f'), Botrytis (Bo, c'and g'), the coculture of wild type Trichoderma and Botrytis (wt Tr+Bo, d' and h') and the coculture of Trichoderma Δ ech42 mutant and Botrytis (Δ ech42+Bo, e'and i'). For each treatment light (a-i) and fluorescence (a'-i') microscope images of the same field are presented. All images were acquired with the same exposition time gauged to the higher fluorescence emission intensity obtained with the Botrytis <3 kDa fraction. Pictures represent typical examples after 10 min treatment. Bar: 10 μm.Back to article page
