A classification for extant ferns
TLDR
A revised classification for extant ferns is presented, with emphasis on ordinal and familial ranks, and a synopsis of included genera is provided, reflecting recently published phylogenetic hypotheses based on both morphological and molecular data.
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences.
The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our
Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants
TLDR
It is shown that there are three monophyletic groups of extant vascular plants: (1) lycophytes, (2) seed plants and (3) a clade including equisetophytes (horsetails, psilotophytes) and all eusporangiate and leptosporangiates ferns.
The Selaginella Genome Identifies Genetic Changes Associated with the Evolution of Vascular Plants
TLDR
The genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported, is reported, finding that the transition from a gametophytes- to a sporophyte-dominated life cycle required far fewer new genes than the Transition from a non Seed vascular to a flowering plant.
Complete plastome sequences of Equisetum arvense and Isoetes flaccida: implications for phylogeny and plastid genome evolution of early land plant lineages
TLDR
Results from this study demonstrate resolution among the four monilophytes lineages, albeit with moderate support; and posit a clade consisting of Equisetaceae and Psilotaceae that is sister to the "true ferns," including Marattiaceae.
A community‐derived classification for extant lycophytes and ferns
TLDR
A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.
Complete nucleotide sequence of the chloroplast genome from a leptosporangiate fern, Adiantum capillus-veneris L.
TLDR
The complete nucleotide sequence of the chloroplast genome of the leptosporangiate fern, Adiantum capillus-veneris L. (Pteridaceae) is determined and all but one of the tRNA genes necessary to encode the complete repertoire required for translation are found.
De novo characterization of the gametophyte transcriptome in bracken fern, Pteridium aquilinum
TLDR
This study is the first comprehensive transcriptome analysis for a fern and represents an important scientific resource for comparative evolutionary and functional genomics studies in land plants and demonstrates the utility of high-throughput sequencing of a normalized cDNA library for de novo transcriptome characterization and gene discovery in a non-model plant.
Widespread Triploidy in Western North American Aspen (Populus tremuloides)
TLDR
It is demonstrated that triploidy is highest in unglaciated, drought-prone regions of North America, where the largest clone sizes have been reported for this species, and cytotype may be a significant and previously overlooked factor in recent patterns of high aspen mortality in the southwestern portion of the species range.
