A revised generic classification of vittarioid ferns (Pteridaceae) based on molecular, micromorphological, and geographic data
In ferns, as in most branches of the tree of life, phylogenetic analyses of molecular data have greatly improved our ability to identify natural groupings that are subsequently reflected in classifications grounded in the principle of monophyly (Smith & al., 2006; Rothfels & al., 2012; Christenhusz & Chase, 2014). In some cases, the results of such analyses are consistent with earlier notions o...
متن کاملUnique expression of a sporophytic character on the gametophytes of notholaenid ferns (Pteridaceae).
PREMISE OF THE STUDY Not all ferns grow in moist, shaded habitats; some lineages thrive in exposed, seasonally dry environments. Notholaenids are a clade of xeric-adapted ferns commonly characterized by the presence of a waxy exudate, called farina, on the undersides of their leaves. Although some other lineages of cheilanthoid ferns also have farinose sporophytes, previous studies suggested th...
متن کاملA phylogenetic analysis of Rhamnaceae using rbcL and trnL-F plastid DNA sequences.
Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation of large and otherwise heterogeneous groups. We evaluated the most recent classification with DNA sequences of two regions of the plastid genome, rbcL and trnL-F, from 42 genera of Rhamnaceae and representatives of the related families Elaeagnaceae, Barbeyaceae, Dirachmaceae, Urticac...
متن کاملUse of rbcL and trnL-F as a Two-Locus DNA Barcode for Identification of NW-European Ferns: An Ecological Perspective
Although consensus has now been reached on a general two-locus DNA barcode for land plants, the selected combination of markers (rbcL + matK) is not applicable for ferns at the moment. Yet especially for ferns, DNA barcoding is potentially of great value since fern gametophytes--while playing an essential role in fern colonization and reproduction--generally lack the morphological complexity fo...
متن کاملMycorrhizal association in gametophytes and sporophytes of the fern Pteris vittata (Pteridaceae) with Glomus intraradices.
A Ferns, which are usually colonizing different environments and their roots frequently present mycorrhization, have two adult stages in their life cycle, the sporophytic and the gametophytic phase. This paper describes the experimental mycorrhizal association between Pteris vittata leptosporangiate fern and a strain of Glomus intraradices during the life cycle of the fern, from spore germinati...
