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 ...

Fungal diversity and ex vitro symbiotic germination of Serapias vomeracea (Orchidaceae) [PDF]

, 2022
Conservation of orchids can be possible with effective seed germination and seedling growth methods. In this context, ex vitro symbiotic seed germination and seedling growth of orchid seeds may be convenient and advantageous.

Root-Associated Endophytic and Mycorrhizal Fungi from the Epiphytic Orchid Maxillaria acuminata in a Tropical Montane Forest in Southern Ecuador

Diversity, 2022
In natural environments, it has been shown that orchids interact with multiple microorganisms including various species of fungi that colonize their tissues.

Analysis of fungal communities in roots and root-associated soil of Nervilia fordii from karst areas of Guangxi

Guangxi Zhiwu, 2023
To explore the fungal community diversity in the roots of Nervilia fordii as well as in the root-associated soil, we collected the terrestrial orchids grown in Daxin (DX) County and Longzhou (LZ) County of the karst areas in Guangxi Zhuang Autonomous ...

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

A narrow group of monophyletic Tulasnella (Tulasnellaceae) symbiont lineages are associated with multiple species of Chiloglottis (Orchidaceae): Implications for orchid diversity [PDF]

American Journal of Botany, 2010
• Premise of the study: The Orchidaceae is characterized by exceptional species diversity. Obligate orchid mycorrhizae are predicted to determine orchid distributions, and highly specific relationships between orchids and fungi may drive orchid diversification.

The epiphytic orchid Vanda falcata is predominantly associated with a single Tulasnellaceae fungus in adulthood, and Ceratobasidiaceae fungi strongly induce its seed germination in vitro

Plant Species Biology, 2023
Abstract Vanda falcata is an epiphytic orchid native to East Asia with high horticultural and ornamental value. However, its wild populations are at risk of extinction due to overcollection and habitat loss.

Further advances in orchid mycorrhizal research [PDF]

, 2007
Orchid mycorrhizas are mutualistic interactions between fungi and members of the Orchidaceae, the world’s largest plant family. The majority of the world’s orchids are photosynthetic, a small number of species are myco-heterotrophic throughout their ...

Does Climate Change Pose a Threat to the Guild Mimicry System of Australian Orchids? [PDF]

Ecol Evol
In this study we forecast the effect of climate change on the distribution of food‐deceptive orchid species whose pollination strategy relies on a strict association with pollinators and co‐occurring rewarding model plants. The approach used in our study can serve as a model for understanding the potential effects of climate change on the strength of ...
