Infection structures of F. graminearum wild type isolate 8/1 on wheat cv Nandu. A-D Light microscopy of infected palea after trypan blue staining of mycelium at 10 dpi. A Abundance of infection cushions (blue) on the surface of palea under white light conditions using MZFLIII microscope. Different sizes of infection cushions and necroses of plant cells (white arrowhead) surrounding big infection cushions is remarkable, scale bar = 200 μm. B-D Higher magnification using Zeiss Axio Imager.Z1 reveals different infection structures. B Magnification of blue stained fungal structure (red arrowhead in A) showing a typical infection cushion, scale bar = 50 μm. C Typical cellular structure of a lobate appressorium and D foot structure arising from runner hyphae, scale bars = 10 μm. Abbreviations: FS Foot structures, IC infection cushions, LA lobate appressorium, RH runner hypha, S septum.
