    Notes: Summary Tubercles of Pseudotsuga menziesii consisted of clusters of ectomycorrhizae surrounded by a peridiumlike rind. Energy dispersive spectroscopy demonstrated that crystals found in the zone of loose hyphae extending from the inner rind to the mantle of each root probably contain calcium oxalate. Inner mantle and Hartig net hyphae showed a labyrinthine branching pattern and stored carbohydrates and protein. The Hartig net formed up to inner cortical cells which had thickened, darkly stained walls. Bacteria were located either along with hyphae within the rind or as colonies on the surface of the tubercle.

    Occurrence of nitrogen-fixing Azospirillum in vesicular-arbuscular mycorrhizal fungi (1989)

    Notes: Abstract Nitrogenase activity measured by acetylene reduction, was detected when surface-sterilized spores of vesicular-arbuscular (VA) mycorrhizal fungi (Glomus fasciculatum, G. intraradices, G. scientillans, G. mosseae, Gigaspora gilmorei andEndogone dusii) were inoculated into nitrogen-free liquid medium containing malic acid and incubated under microaerophilic conditions (99% N2+1% O2) at 30°C.Azospirillum species were isolated from the nitrogenase-active cultures.
