CELLULOSE AS A CARBON SOURCE FOR ORCHID MYCORRHIZA [PDF]
New Phytologist, 1969 SummaryOrchid endophyte fungi are known to utilize cellulose and translocate carbon compounds into protocorms. Evidence is presented which indicates that cellulose is an excellent carbon source for protocorm growth in a variety of orchid‐fungus systems including both temperate and tropical orchids.

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 448-466, March 2025.Rafflesia is a genus of parasitic plants with the largest flowers in the world, unique to the threatened forest habitats of tropical Asia. Here, we report on genes that are active (the transcriptome) in Rafflesia seeds as part of a larger effort to understand Rafflesia.

Journal of Ecology, Volume 113, Issue 3, Page 635-648, March 2025.Population viability of the long‐lived orchid Gymnadenia conopsea increased with population size, but not with genetic diversity. Larger populations had higher and more stable adult survival, suggesting favourable habitats that buffer effects of climatic variation.

Fungi associated with terrestrial orchid mycorrhizas, seeds and protocorms
Mycoscience, 1996 The identity and ecological role of fungi in the mycorrhizal roots of 25 species of mature terrestrial orchids and in 17 species of field incubated orchid seedlings were examined. Isolates of symbiotic fungi from mature orchid mycorrhizas were basidiomycetes primarily in the generaCeratorhiza, Epulorhiza andMoniliopsis; a few unidentified taxa with ...

Cell-specific expression of plant nutrient transporter genes in orchid mycorrhizae
Plant Science, 2017 Orchid mycorrhizal protocorms and roots are heterogeneous structures composed of different plant cell-types, where cells colonized by intracellular fungal coils (the pelotons) are close to non-colonized plant cells. Moreover, the fungal coils undergo rapid turnover inside the colonized cells, so that plant cells containing coils at different ...

Trophic relationships in orchid mycorrhiza – diversity and implications for conservation
Lankesteriana, 2015 Orchid species are perennial, and though demo- graphic data suggest that the family includes r- as well as K-strategists (Whigham & Willems 2003), most species are potentially long-lived. Individual plants may be kept in living plant collections or in nature reserves for practically unlimited periods of time.

Some Orchid Species Fungi Isolated by Different Methods
Türkiye Tarımsal Araştırmalar Dergisi, 2014 Due to their very small seeds that do not contain endosperm, many terrestrial orchid species require the presence of fungi in order to germinate and maintain their lives; and symbiotic culture studies are being carried out on this topic.

Current Opinion in Plant BiologyGibberellin (GA) is a classical plant hormone that regulates many physiological processes, such as plant growth, development, and environmental responses. GA inhibits arbuscular mycorrhizal (AM) symbiosis, the most ancient and widespread type of mycorrhizal symbiosis. Knowledge about mycorrhizal symbioses at the molecular level has been obtained mainly
