Orchid mycorrhiza: implications of a mycophagous life style

Oikos, 2009
Orchid 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 ...

Fine structure of the host-fungus interface in orchid mycorrhiza

Planta, 1971
Electron 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.

ORCHID MYCORRHIZA: VITAMIN PRODUCTION AND REQUIREMENTS BY THE SYMBIONTS

American Journal of Botany, 1973
A Rhizoctonia species isolated from Cymbidium has been cultured successfully on a defined medium consisting of minerals, sugar, thiamine, and folic acid. Thiamine can be replaced by its thiazole component, which is probably produced by germinating orchids.

At the core of the endomycorrhizal symbioses: intracellular fungal structures in orchid and arbuscular mycorrhiza

New Phytologist, 2023
Arbuscular (AM) and orchid (OrM) mycorrhiza are the most widespread mycorrhizal symbioses among flowering plants, formed by distinct fungal and plant species.

Biogeography of orchid mycorrhizas

2017
Most 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.

Study of Orchid Mycorrhiza Fungi (Omf) on Phalaenopsis Violacea Drought Strees

Pakistan Journal of Phytopathology
Water stress is a plant disease that is abiotic in nature and affects the growth of orchid species in nature. Economically, it is very detrimental because it can cause losses in orchid production.

Fungi from orchid mycorrhizas

1997
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 ...

Observations on orchid seed mycorrhizae

Mycopathologia et Mycologia Applicata, 1969
In 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.
