Biogeography of orchid mycorrhizas
2017Most orchid mycorrhizal fungi (OMF) are free-living decomposers that do not depend on orchids for establishment or survival. Despite their importance for completion of the orchid life cycle, the geographical distribution of OMF remains poorly understood.

An important step in studies of orchid mycorrhizas is identification of the mycobionts (Table 4-1; epithets may have changed since reported). Generally, these have been shown to be members of the Subdivision Basidiomycotina (frequently referred to informally using an old Class name, ‘basidiomycetes’) which can form characteristic intracellular masses ...

Induced DNA synthesis in orchid mycorrhiza
Planta, 1970The distribution of DNA values in the cortex of mycorrhizal and non-mycorrhizal roots of Dactylorhiza purpurella and Spathoglottis plicata has been studied by Feulgen microdensitometry. Endoreduplication occurs during differentiation of cortical parenchyma.

Orchid mycorrhiza: implications of a mycophagous life style
Oikos, 2009Orchid mycorrhiza probably affects about 25 000 plant species and thus roughly one tenth of all higher plants. Histologically, this symbiosis resembles other kinds of endomycorrhiza, the fungal hyphae growing within living plant cells. Considerable evidence, however, suggests that it is not a two‐way exchange relationship and thus not potentially ...

Observations on orchid seed mycorrhizae
Mycopathologia et Mycologia Applicata, 1969In the natural germination of orchid seeds, the fungus undoubtedly contributes sugars, auxins, and growth factors in stimulating the growth of the embryo. However, none of these factors alone are as successful in stimulating germination as they are when combined.

Acid phosphatase and esterase activity in orchid mycorrhiza
Planta, 1973A cytochemical study was made to examine the possibility that acid phosphatase may be specifically involved in the digestion of endophytic hyphae in orchid mycorrhiza. Esterase activity was studied for comparison. Frozen sections of unfixed or glutaraldehyde-fixed protocorms of Dactylorhiza purpurella infected by Thanatephorus cucumeris (Rhizoctonia ...

Fine structure of the host-fungus interface in orchid mycorrhiza
Planta, 1971Electron microscopy of protocorms of Dactylorhiza purpurella infected with a symbiotic Rhizoctonia sp. showed that the intracellular hyphae examined did not penetrate the plasmalemma of the host cell. Walls of hyphae within cells bore many hemispherical protuberances over which the host plasmalemma was closely pressed.
