The Waiting Room Hypothesis revisited by orchids: were orchid mycorrhizal fungi recruited among root endophytes? [PDF]
Ann Bot, 2022 Background As in most land plants, the roots of orchids (Orchidaceae) associate with soil fungi. Recent studies have highlighted the diversity of fungal partners involved, mostly within Basidiomycotas. The association with a polyphyletic group of fungi collectively called rhizoctonias (Ceratobasidiaceae, Tulasnellaceae and Serendipitaceae) is the most ...

Habitat Disturbance Promotes Shifts in the Abundance of Major Fungal Phyla in the Roots of a Native Orchid, Tipularia discolor [PDF]
Plant-Environment InteractionsOrchids are a widely distributed group of flowering plants with important roles in ecosystems around the globe. However, many species are in decline due, in part, to human‐driven changes in their habitat.

Mycorrhizal Associations and Trophic Modes in Coexisting Orchids: An Ecological Continuum between Auto- and Mixotrophy [PDF]
Frontiers in Plant Science, 2017 Two distinct nutritional syndromes have been described in temperate green orchids. Most orchids form mycorrhizas with rhizoctonia fungi and are considered autotrophic.

Variability in Nutrient Use by Orchid Mycorrhizal Fungi in Two Medium Types. [PDF]
J Fungi (Basel), 2023 Orchid mycorrhizal fungi (OMF) from the rhizoctonia aggregate are generally considered to be soil saprotrophs, but their ability to utilize various nutrient sources has been studied in a limited number of isolates cultivated predominantly in liquid media, although rhizoctonia typically grow on the surface of solid substrates. Nine isolates representing

Isolation and identification of beneficial orchid mycorrhizal fungi in Paphiopedilum barbigerum (Orchidaceae). [PDF]
Plant Signal Behav, 2022 Seed germination and seedling development in nearly all orchid species rely on a symbiotic relationship with mycorrhizal fungi; however, this is not the case with all mycorrhizal fungi. This study aims to provide an understanding about the important role of mycorrhiza in seed germination and growth of Paphiopedilum barbigerum.

Comparison and structure of fungal diversity in roots and rhizosphere soils of wild and reintroduced populations of three Paphiopedilum species [PDF]
BMC GenomicsMycorrhizal fungi play critical roles in the seed germination and the growth of orchid plants. The investigation of fungi, especially mycorrhizal fungi, associated with orchid roots is important for both the protection and sustainable utilization of the ...

Continental-scale distribution and diversity of Ceratobasidium orchid mycorrhizal fungi in Australia. [PDF]
Ann Bot, 2021 AbstractBackground and AimsMycorrhizal fungi are a critical component of the ecological niche of most plants and can potentially constrain their geographical range. Unlike other types of mycorrhizal fungi, the distributions of orchid mycorrhizal fungi (OMF) at large spatial scales are not well understood.

Colonization by orchid mycorrhizal fungi primes induced systemic resistance against necrotrophic pathogen. [PDF]
Front Plant SciAbstractOrchids and arbuscular mycorrhiza (AM) plants evolved independently and have different structures and fungal partners, but they both facilitate nutrient uptake. Orchid mycorrhiza (OM) supports orchid seed germination, but unlike AM, its role in disease resistance of mature plants is largely unknown. Here, we examined whether OM induces systemic

Shallow Genome Sequencing for Phylogenomics of Mycorrhizal Fungi from Endangered Orchids [PDF]
, 2019 Most plant species form symbioses with mycorrhizal fungi and this relationship is especially important for orchids. Fungi in the genera Tulasnella, Ceratobasidium, and Serendipita are critically important for orchid germination, growth and development ...
