Antibacterial evaluation and preliminary phytochemical screening of selected ferns from Iran
Background and objectives: The main aims of this study have been finding out the antibacterial activity and preliminary phytochemical screening of some fern species. Methods: The antimicrobial activity of the methanol extracts of Polypodium interjectum Shivas, Polystichum woronowii Fomin, Polystichum aculeatum (L.) Roth., Dryopteris affinis (Lowe) Fraser-Jenk...
متن کاملFERNS AND FERN ALLIES OF IRAN
The pteridophyte account of Flora Iranica (ed. K.H. Rechinger) is still not published. The Caspian forests provide suitable habitats for the growth of many ferns and fern allies in Iran. In semi-arid and mountainous areas of Iran, mesophilous plants are restricted to rock crevices, waterfall proximity, stream banks and lake shores. Based on field collections and study of herbarium specimens in ...
متن کاملAdiantum capillus-veneris Linn. (Maidenhair fern) in modern phytotherapy
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...
متن کاملCharacterization of MADS homeotic genes in the fern Ceratopteris richardii.
The MADS genes encode a family of transcription factors, some of which control the identities of floral organs in flowering plants. To understand the role of MADS genes in the evolution of floral organs, five MADS genes (CMADS1, 2, 3, 4, and 6) were cloned from the fern Ceratopteris richardii, a nonflowering plant. A gene tree of partial amino acid sequences of seed plant and fern MADS genes sh...
متن کاملGenome sequencing provides insight into the reproductive biology, nutritional mode and ploidy of the fern pathogen Mixia osmundae.
Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed the genome of M. osmundae, focusing on genes that may provide some insight into its mode of pathogenicity and reproductive biology. Mixia osmundae has the smallest plant pathogenic basidiomycete genome sequenced to date...
