Ap Applicati tions ons in in Pl Plant t Scien Sciences ces Myriopteris Fée is an early diverging lineage of cheilanthoid ferns (Pteridaceae) that contains approximately 47 species encompassed within three major clades—all of which, until recently , were circumscribed in the large, polyphyletic genus, Cheilanthes Sw. (Grusz and Windham, 2013 ; Grusz et al., 2014). The covillei clade is the large...

Background and objectives: Maidenhair fern is an herbal medicine belonging to the family Pteridaceae which is extensively found in Atlantic coast as far as Ireland, America and Iran. The fronds of Adiantum capillus-veneris are prescribed for treatment of different diseases. Different phytochemical compositions such as flavonoids, alkaloids, tannins, terpenoids, etc...

We determined the complete nucleotide sequence of the chloroplast genome of the leptosporangiate fern, Adiantum capillus-veneris L. (Pteridaceae). The circular genome is 150,568 bp, with a large single-copy region (LSC) of 82,282 bp, a small-single copy region (SSC) of 21,392 bp and inverted repeats (IR) of 23,447 bp each. We compared the sequence to other published chloroplast genomes to infer...

Four new bibenzyl derivatives were isolated, together with other known bibenzyls, by bioassay-guided fractionation of a CHCl₃-MeOH extract of Notholaena nivea Desv. (Pteridaceae) aerial parts. The structures were elucidated by NMR, ESIMS and other spectral analyses. Their antioxidative effects towards superoxide, lipidic peroxidation and the 2,2'-azino-bis-3-ethilbenzothiazoline-6-sulfonic acid...

The fern Pteris vittata tolerates and hyperaccumulates exceptionally high levels of the toxic metalloid arsenic, and this trait appears unique to the Pteridaceae. Once taken up by the root, arsenate is reduced to arsenite as it is transported to the lamina of the frond, where it is stored in cells as free arsenite. Here, we describe the isolation and characterization of two P. vittata genes, AC...
