    Root apical meristems ofAllium porrum L. as affected by arbuscular mycorrhizae and phosphorus

    Arbuscular mycorrhizal (AM) fungi significantly improve plant growth in soils with low phosphorus availability and cause many changes in root morphology, similar to those produced by increased P nutrition, mai...

    Chromatin structure variation in successful and unsuccessful arbuscular mycorrhizas of pea

    Lincoln and Frisson varieties of endomycorrhiza-forming pea plants and isogenic mycorrhiza-resistant Frisson mutant (P2) plants were inoculated withGlomus mosseae. Nuclei released from inoculated and non-inoculat...

    Nuclear morphology and ploidy level in infected and uninfected hair root cells ofCalluna vulgaris andVaccinium myrtillus mycorrhizae

    Morphometry, microfluorimetry and electron microscopy were used to investigate the size, ploidy level, and morphology of host nuclei in the ericoid mycorrhizal systemsCalluna vulgaris+Hymenoscyphus ericae andVacc...

    Membrane potential hyperpolarisation in vesicular arbuscular mycorrhizae ofAllium porrum L.: a non-nutritional long-distance effect of the fungus

    Variations in membrane potential difference (PD) were observed between root cortical cells ofAllium porrum plants, uninfected and infected withGlomus E3: cell membrane potential was constantly hyperpolarised in t...

    The mitotic cycle in root apical meristems ofAllium porrum L. is controlled by the endomycorrhizal fungusGlomus sp. strain E3

    The mitotic cycle in root apical meristems of mycorrhizal and non-mycorrhizal plants ofAllium porrum L.+Glomus sp., strain E3, has been examined by3H-TdR labelling. Significant slowing down of the mitotic cycle i...
