In vitro symbiotic seed germination in Vanda wightii, an endemic orchid species of Western Ghats, India supported by Ceratobasidiaceae isolates [PDF]
Plant Science Today, 2023 Symbiotic seed germination for conservation and cultivation of orchids holds colossal merit asmycorrhizal fungus in its system improves their growth and adaptability. Symbiotic activity ishighly specific in some species, but in other cases the same fungus from one species is effective in aseries of related species.

Habitat Disturbance Promotes Shifts in the Abundance of Major Fungal Phyla in the Roots of a Native Orchid, <i>Tipularia discolor</i>. [PDF]
Plant Environ InteractABSTRACT Orchids 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. It is well established that orchids are reliant on specific groups of mycorrhizal fungi for growth and reproduction and that these fungi can

Mixotrophy in orchids: facts, questions, and perspectives. [PDF]
New PhytolSummary While orchids germinate thanks to carbon from their symbiotic fungi, variable carbon exchanges exist between adult orchids and their mycorrhizal fungi. Although some truly autotrophic orchids reward their fungi with carbon at adulthood, some species remain achlorophyllous and fully dependent on fungal carbon (mycoheterotrophy).

Fungal association and root morphology shift stepwise during ontogenesis of orchid Cremastra appendiculata towards autotrophic nutrition. [PDF]
AoB Plants, 2022 The chlorophyllous, terrestrial orchid Cremastra appendiculata from East Asia is unique concerning its fungal mycorrhiza partners. The initially mycoheterotrophic protocorms exploit rather specialized non-rhizoctonia saprotrophic Psathyrellaceae.

Subterranean morphology underpins the degree of mycoheterotrophy, mycorrhizal associations, and plant vigor in a green orchid Oreorchis patens. [PDF]
Plant JSignificance Statement The evolution of full heterotrophy from photosynthetic ancestors is a longstanding question in evolutionary ecology. Our study demonstrates that coralloid rhizomes in a photosynthetic orchid promote greater mycoheterotrophic carbon acquisition, leading to more vigorous flowering scapes and increased flower production.

Global Ecology and Conservation, 2022 Because orchid mycorrhizal fungi are important for orchid seed germination, addition of germination-supporting fungal inoculum to the soil can be an efficient way to improve in situ seed germination of terrestrial orchids, but empirical evidence is still

The Diversity of Root-Associated Endophytic Fungi from Four Epiphytic Orchids in China
Diversity, 2021 Root-associated endophytic fungi (RAF) are found asymptomatically in almost all plant groups. However, little is known about the compositions and potential functions of RAF communities associated with most Orchidaceae species.

EFFECT OF TEMPERATURE, pH AND ESSENTIAL OILS ON THE MYCELIAL GROWTH OF RHIZOCTONIA SOLANI Kühn (CANTHARELLALES: CERATOBASIDIACEAE) ISOLATES [PDF]
Journal of microbiology, biotechnology and food sciences, 2020 This research aimed to study diversity among a collection of Rhizoctonia solani strains, isolated from many crops in Morocco, based on radial mycelial growth on potato dextrose agar (PDA) at different pH and temperature levels. The in vitro antifungal efficacy of essential oils (EOs) derived from aromatic and medicinal plants of Thymus vulgaris ...

Mixotrophy of Platanthera minor, an orchid associated with ectomycorrhiza‐forming Ceratobasidiaceae fungi [PDF]
New Phytologist, 2011 • We investigated the fungal symbionts and carbon nutrition of a Japanese forest photosynthetic orchid, Platanthera minor, whose ecology suggests a mixotrophic syndrome, that is, a mycorrhizal association with ectomycorrhiza (ECM)-forming fungi and partial exploitation of fungal carbon.
