To determine the mycorrhizal status of pteridophyte gametophytes in diverse taxa, the mycorrhizal colonization of wild gametophytes was investigated in terrestrial cordate gametophytes of pre-polypod leptosporangiate ferns, i.e., one species of Osmundaceae (Osmunda banksiifolia), two species of Gleicheniaceae (Diplopterygium glaucum, Dicranopteris linearis), and four species of Cyatheales including tree ferns (Plagiogyriaceae: Plagiogyria japonica, Plagiogyria euphlebia; Cyatheaceae: Cyathea… Expand
Fern gametophytes of Angiopteris lygodiifolia and Osmunda japonica harbor diverse Mucoromycotina fungi
It is found that Mucoromycotina were present in fern gametophytes of Marratiales and Osmundales, which implies that a variety of fern taxa have MucOromycotinas associations. Expand
Mycorrhizal relationships in Lycophytes and Ferns
There are no experimental studies on the benefits of mycorrhizae for ferns, but field experiments suggest that there is a fine balance between positive and negative effects, so that many fern species have disposed of the fungi either generally or facultatively. Expand
Micorriza arbuscular, Mucoromycotina y hongos septados oscuros en helechos y licófitas con distribución en México: una revisión global
To understand the role that plays the mycorrhiza in the establishment of ferns and lycophytes, it is necessary to include the gametophytic face in ecological, molecular and physiological experimental studies, and this information is important to implement conservation strategies. Expand

This study investigated the endophytic fungal diversity within roots and sporophore of an endangered Korean fern, and compared it to fungi in surrounding soil using a metabarcoding approach, suggesting that various fungal species are associated with ferns. Expand
Pteridophyte fungal associations: Current knowledge and future perspectives
A critical review of current knowledge of fungal associations across pteridophytes is provided and future directions making recommendations along the way are considered, finding the best conclusion that can be reached is that the fungal symbionts of pterids belong to the two fungal lineages Mucoromycotina and Glomeromycota.

An update and reassessment of fern and lycophyte diversity data in the Japanese Archipelago
The fern and lycophyte flora of Japan comprising 721 native taxa (including subspecies and varieties) plus 371 interspecific hybrids was reassessed using a nearly comprehensively sampled distributionExpand
Marchantia polymorpha subsp. ruderalis (Bischl. & Boissel.-Dub.)-arbuscular mycorrhizal fungi interaction: beneficial or harmful?
A reduction in its growth and viability of its tissues was observed, in addition to an increase only in nutritional content of those elements related to plant defenses, together with the reactive oxygen species (ROS) content, in this study. Expand
The Early Cretaceous Apple Bay flora of Vancouver Island: a hotspot of fossil bryophyte diversity1
Studies of an anatomically preserved Early Cretaceous (Valanginian) plant fossil assemblage on Vancouver Island (British Columbia), at Apple Bay, focusing on the cryptogamic flora, have revealed an abundant bryophyte component. Expand
History and Natural History of Plants and Their Associates
The order Charales in the division Charophyte adapted to life in ephemeral freshwater pools, which frequently dry up, and in the Coleochaete, plural meiospores are produced from a zygote, suggesting that embryos are protected and nourished in maternal tissue. Expand


Arbuscular mycorrhiza formation in cordate gametophytes of two ferns, Angiopteris lygodiifolia and Osmunda japonica
Mycorrhizal formation in wild fern gametophytes, based on large-scale sampling with molecular identification of host plant species, was demonstrated for the first time and results suggest that A.lygodiifolia and O.japonica gamETophytes consistently form arbuscular mycorrhIZae. Expand
Mycothallic/mycorrhizal symbiosis of chlorophyllous gametophytes and sporophytes of a fern, Pellaea viridis (Forsk.) Prantl (Pellaeaceae, Pteridales)
Gametophytes of Pellaea viridis that appeared spontaneously on the surface of substratum originating from an ultramafic area were found to form mycothallic symbiosis with arbuscular mycorrhizal fungi (AMF) under laboratory conditions and resulted in the development of larger leaf area and root length of the sporophyte. Expand
Arbuscular mycorrhizal associations in Lycopodiaceae.
The results suggest that most mycoheterotrophic plants that form AM associations do so with restricted clades of Glomus A, and raises the possibility that photosynthetic sporophytes are a source of carbon to conspecific myco heterotrophic gametophytes via shared fungal networks. Expand
Phylogenetic affinity of arbuscular mycorrhizal symbionts in Psilotum nudum
The correspondence of identities of AM symbionts in P. nudum sporophytes, gametophytes and neighboring angiosperms provides compelling evidence that photosynthetic heterospecific and conspecific plants can serve as the ultimate sources of fixed carbon for mycoheterotrophic gametphytes of P. nudeum, and that the transfer of carbon occurs via shared fungal networks.

Mycorrhizal Associations in Ferns from Southern Ecuador
A survey on the mycorrhizal status of neotropical ferns, focusing on previously neglected taxa, found that dark septate endophytes (DSE) prevailed in epiphytic species and were also common in terrestrial samples of predominantly epipHYtic species. Expand
Arbuscular mycorrhizal and septate endophyte fungal associations in lycophytes and ferns of south India

The occurrence of mycorrhizae in pteridophytes has received little attention in recent years, and Newman and Reddell (1987) found that only 180 species of ferns (fieldcollected) have been examined for mycor rhizae since 1960. Expand
Morphological and molecular analyses of fungal endophytes of achlorophyllous gametophytes of Diphasiastrum alpinum (Lycopodiaceae).
This study suggests a fungus belonging to Sebacinales group B as the main fungal host of the D. alpinum gametophytes, which would explain the steady association of these plants. Expand
