Re-synthesis experiment between eFp and P. tomentosa: A, B the ectomycorrhizal-like structure between eFp and P. tomentosa was photographed using a camera and an ultra-depth of field microscope 40 days after inoculation. The ECM-like root tips were single to pinnately branched, clumped and white to dark brown. The short and swollen lateral roots were ensheathed with eFp mycelia. The photos were adjusted for clarity and contrast as needed; C, D sectioned ECM-like root tips showing extensive hyphal colonisation along the root epidermis and cortex; E longitudinal section of ECM-like root tips showing a dense fungal sheath and fungal invasion of the root cap and epidermis; F, G a magnified view of highly-branched labyrinthine structures formed by irregular hyphal ramification in the inner cortex. All scale bars are shown in each panel.
