Dendrobium is a large genus of tropical epiphytic orchids. Some members of this genus are in danger of extinction across China. To investigate orchid mycorrhizal associations of the genus Dendrobium, plants from two Dendrobium species (Dendrobium officinale and Dendrobium fimbriatum) were collected from two habitats in Guangxi Province, China, and clone(More)
This study investigated the taxonomic identities and diversity of fungal endophytes isolated from four Rhizophoraceae mangrove plant species, Ceriops tagal, Rhizophora apiculata, R. stylosa and Bruguiera sexangula var. rhynchopetala, using a combination of morphological and molecular approaches. Two hundred ninety-five isolates were classified into 38 taxa(More)
During the process of plant domestication, below-ground communities are rarely considered. Some studies have attempted to understand the changes in root symbionts owing to domestication, but little is known about how it influences mycorrhizal response in domesticated crops. We hypothesized that selection for above-ground traits may also result in decreased(More)
Endophytic fungi residing in Panax quinquefolium (American ginseng) have not been well characterized. We collected American ginseng of one-, two-, three- and four-year-old plants cultivated in a forest reserve and identified the endophytic fungal isolates using traditional methods. The colonization frequency and the dominant endophytic fungal species were(More)
Some orchid species are present as epiphytes and lithophytes in the same habitat, but little is known about the differences of their mycorrhizal fungal communities. We used Coelogyne viscosa, which occurs both as an epiphyte and a lithophyte, as a study system to investigate orchid mycorrhizal fungal communities in lithophytes and epiphytes in Xishuangbanna(More)
Molecular techniques are no longer optional for ecologists interested in arbuscular mycorrhizal (AM) communities. Understanding the role of these soil fungi in natural systems requires knowledge of their abundance and identity but this is impossible to achieve without a molecular approach. Adapting molecular tools to AM fungi can be challenging because of(More)
BACKGROUND Polyporus umbellatus is an important medicinal fungus distributed throughout most area of China. Its wide distribution may have resulted in substantial intraspecific genetic diversity for the fungus, potentially creating variation in its medical value. To date, we know little about the intraspecific genetic diversity of P. umbellatus. (More)
Plant phylogeny constrains orchid mycorrhizal (OrM) fungal community composition in some orchids. Here, we investigated the structures of the OrM fungal communities of eight Dendrobium species in one niche to determine whether similarities in the OrM fungal communities correlated with the phylogeny of the host plants and whether the Dendrobium-OrM fungal(More)
Sclerotia of Polyporus umbellatus is a traditional Chinese herb. The sclerotia can survive in soils for long time and their growth depends upon a symbiotic association with Armillariella mellea. But it is unclear whether other fungi reside or play a role in the sclerotia. In this study, wild sclerotial samples were collected from seven provinces, which span(More)
It has been well established that some Armillaria species are symbionts of Polyporus umbellatus, However, little is known about the evolutionary history of P. umbellatus-Armillaria associations. In this research, we used an analysis based on the strength of the phylogenetic signal to investigate P. umbellatus-Armillaria associations in 57 sclerotial samples(More)
