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 Interact
ABSTRACT 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 Phytol
Summary 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).

Subterranean morphology underpins the degree of mycoheterotrophy, mycorrhizal associations, and plant vigor in a green orchid Oreorchis patens. [PDF]

Plant J
Significance 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.

Addition of fungal inoculum increases seed germination and protocorm formation in a terrestrial orchid

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.

Evaluation of Tulasnella and Ceratobasidium as Biocontrol Agents of Fusarium Wilt on Vanilla planifolia

Agronomy, 2023
Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. vanillae (Fov), is a disease that results in significant losses in commercial vanilla production. The genera Ceratobasidium (Ceratobasidiaceae) and Tulasnella (Tulasnellaceae), which are often

Distribution of Core Root Microbiota of Tibetan Hulless Barley along an Altitudinal and Geographical Gradient in the Tibetan Plateau

Microorganisms, 2022
The Tibetan Plateau is regarded as the third pole of the earth and is one of the least explored places on the planet. Tibetan hull-less barley (Hordeum vulgare L. var.

The mycorrhizal community of the epiphytic orchid Thrixspermum japonicum is strongly biased toward a single Ceratobasidiaceae fungus, despite a wide range of fungal partners [PDF]

American Journal of Botany, 2020
PREMISEOrchids depend primarily on mycorrhizal fungi to obtain nutrients throughout their life cycle. Epiphytic orchids account for 69% of orchid diversity. The unstable availability of water and nutrients in their arboreal habitats often results in severe water and nutrient stresses.
