Fig. 3From: Detecting the colonization of ericoid mycorrhizal fungi in Vaccinium uliginosum using in situ polymerase chain reaction and green fluorescent proteinMicroscopic images of V. uliginosum roots colonized by C. ericae and Sordariomycetes sp. wild-type (a, bC. ericae; e, f Sordariomycetes sp.) and by C. ericae and Sordariomycetes sp. expressing GFP (c, dC. ericae; g, h Sordariomycetes sp.). a, c, e, g phase-contrast images; b, d, f, h fluorescent images. Fluorescent fungal coils are visible in the root cells colonized by C. ericae and Sordariomycetes sp. expressing GFP at 2 weeks (d, h). Weak autofluorescence was observed in the root sections of V. uliginosum (b, f). All of the bars are 100 μmBack to article page
