Phylogenetic revision of Dennstaedtioideae (Dennstaedtiaceae: Polypodiales) with description of Mucura, gen. nov.

open access: yesTAXON, 2022
AbstractWe undertook a molecular phylogenetic revision of hayscented ferns (Dennstaedtiaceae: Dennstaedtioideae) using four plastid markers. Our sampling represents ca. 40% of the extant diversity and includes the type species for each of the relevant segregate genera.

Molecular Phylogeny of the Cliff Ferns (Woodsiaceae: Polypodiales) with a Proposed Infrageneric Classification. [PDF]

open access: yesPLoS ONE, 2015
The cliff fern family Woodsiaceae has experienced frequent taxonomic changes at the familial and generic ranks since its establishment. The bulk of its species were placed in Woodsia, while Cheilanthopsis, Hymenocystis, Physematium, and Protowoodsia are ...

Subgenome evolutionary dynamics in allotetraploid ferns: insights from the gene expression patterns in the allotetraploid species Phegopteris decursivepinnata (Thelypteridaceae, Polypodiales) [PDF]

open access: yesFrontiers in Plant Science, 2023
Allopolyploidization often leads to disruptive conflicts among more than two sets of subgenomes, leading to genomic modifications and changes in gene expression.

Comparative analysis of inverted repeats of polypod fern (Polypodiales) plastomes reveals two hypervariable regions

open access: yesBMC Plant Biology, 2017
Background Ferns are large and underexplored group of vascular plants (~ 11 thousands species). The genomic data available by now include low coverage nuclear genomes sequences and partial sequences of mitochondrial genomes for six species and several ...

Structural Variation of Plastomes Provides Key Insight Into the Deep Phylogeny of Ferns [PDF]

open access: yesFrontiers in Plant Science, 2022
Structural variation of plastid genomes (plastomes), particularly large inversions and gene losses, can provide key evidence for the deep phylogeny of plants.

Polypodiales a promising fern order as a source of anticancer agent: A comprehensive review

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Ferns are vascular plants that have been extensively studied in recent decades for their phytochemical and anticancer activities. Polypodiales is an order of ferns consisting of 26 families with more than 9600 species (>80% of the total number of fern ...

Phenolic compounds in species of the Blechnaceae. [PDF]

open access: yesPlant Biol (Stuttg)
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

An efficient and effective RNA extraction protocol for ferns. [PDF]

open access: yesAppl Plant Sci
Abstract Premise The extraction of high‐quality RNA is the critical first step for the analysis of gene expression and gene space. This remains particularly challenging in plants, and especially in ferns, where the disruption of the cell wall and separation of organic compounds from nucleic acids is not trivial.

Is There a Key Primer for Amplification of Core Land Plant DNA Barcode Regions (rbcL and matK)? [PDF]

open access: yesEcol Evol
We use in silico PCR to select and measure the amplification capability of primer. We tested 366 and 489 published primers for the rbcL and matK regions, respectively, using sequences from 8463 different land plant species. Our results indicate a set of primers that effectively cover all land plant sequences, particularly for the rbcL region.
