    Arbuscular mycorrhizal modifications to plant root systems: scale, mechanisms and consequences

    Plant root systems serve a variety of different functions at the plant, community and ecosystem scales. For the plant they provide stability for the shoot, an organ for uptake, transport and storage of water a...

    IAA and ZR content in leek (Allium porrum L.), as influenced by P nutrition and arbuscular mycorrhizae, in relation to plant development

    Leek plants (Allium porrum L.), infected or not with the arbuscular mycorrhizal (AM) fungus, Glomus mosseae, were grown in a sand-hydroponic system, fed with a nutrient solution containing 3.2 or 96 μM P and anal...

    Polyploidy in tomato roots as affected by arbuscular mycorrhizal colonization

    Nuclear changes in roots of tomato (Lycopersicon esculentum), a plant with a small genome, during the establishment of arbuscular mycorrhizal (AM) colonization were studied using light and electron microscopy, as...

    Quantification of AMF-Induced Modifications to Root System Architecture and Longevity

    The growth of a functional root system is essential to the development and survival of terrestrial plants. Obvious functions include anchorage and nutrient and water uptake but other, less obvious, functions s...

    Interactions between the soilborne root pathogenPhytophthora nicotianae var.parasitica and the arbuscular mycorrhizal fungusGlomus mosseae in tomato plants

    In order to study the influence of Arbuscular Mycorrhiza (AM) on the development of root rot infection, tomato plants were raised with or withoutGlomus mosseae and/orPhytophthora nicotianae var.parasitica in a sa...

    Impact of mycorrhizal colonisation on root architecture, root longevity and the formation of growth regulators

    Until relatively recently, it was assumed that arbuscular mycorrhizal fungi (AMF) did not influence the morphology of the root system. (1983) concluded “little change in root morphology occurs following infection...

    Apical meristems in mycorrhizal and uninfected roots ofCalluna vulgaris (L.) Hull

    Calluna vulgaris root meristems, either uninfected or infected byPezizella ericae, were compared using light and transmission electron microscopy. In lightly infected ‘hair’ roots, active tips contained initial ...
