Co‐occurring orchid species associated with different low‐abundance mycorrhizal fungi from the soil in a high‐diversity conservation area in Denmark [PDF]

Ecology and Evolution
Plant–fungal interactions are ubiquitous across ecosystems and contribute significantly to plant ecology and evolution. All orchids form obligate symbiotic relationships with specific fungi for germination and early growth, and the distribution of ...

Co-Cultures of Mycorrhizal Fungi Do Not Increase Germination and Seedling Development in the Epiphytic Orchid Dendrobium nobile [PDF]

Frontiers in Plant Science, 2020
Orchids are highly dependent on mycorrhizal fungi for seed germination and subsequent growth to a seedling as they provide essential carbon, water, and mineral nutrients to developing seeds. Although there is mounting evidence that orchid seeds are often

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.

The endangered epiphytic orchid Dendrobium okinawense has a highly specific mycorrhizal association with a single Tulasnellaceae fungus [PDF]

Journal of Forest Research, 2021
Epiphytic orchids, which account for 68% of vascular epiphytes, contribute substantially to plant species diversity in forest canopies.

Dominant Dendrobium officinale mycorrhizal partners vary among habitats and strongly induce seed germination in vitro

Frontiers in Ecology and Evolution, 2022
Dendrobium officinale (Orchidaceae) is an endangered epiphytic orchid that has been well studied as a medicinal plant. Although previous studies have shown that various fungal isolates promote D.

Dynamic Shifts in the Root Microbiota of Cultivated Paphiopedilum armeniacum during Different Stages of Growth

Diversity, 2022
Paphiopedilum armeniacum S. C. Chen et F. Y. Liu is an endangered lady’s slipper orchid species with high horticultural value. As observed for other orchids, mycorrhizal fungi and endophytic bacteria play important roles in the growth and development of ...

Symbiotic Culture of Three Closely Related Dendrobium Species Reveals a Growth Bottleneck and Differences in Mycorrhizal Specificity at Early Developmental Stages

Diversity, 2022
Mycorrhizal specificity, i.e., the range of fungi allowing mycorrhizal partnerships, differs among orchid species, but that at early developmental stages is unclear.

Cryptostylis species (Orchidaceae) from a broad geographic and habitat range associate with a phylogenetically narrow lineage of Tulasnellaceae fungi

Fungal Biology, 2022
While many Australian terrestrial orchids have highly specialized mycorrhizal associations, we tested the hypothesis that the geographically widespread orchid genus Cryptostylis associates with a diversity of fungal species. Using fungal isolation and molecular approaches, we investigated the mycorrhizal associations of five Australian Cryptostylis ...
