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.
Ferns diversified in the shadow of angiosperms
TLDR
It is shown that polypod ferns (> 80% of living fern species) diversified in the Cretaceous, after angiosperms, suggesting perhaps an ecological opportunistic response to the diversification of angios perms, as angiosPerms came to dominate terrestrial ecosystems.
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…
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
TLDR
The scope of the analysis provides unprecedented insight into overall fern relationships, not only delivering additional support for the deepest leptosporangiate divergences, but also uncovering the composition of more recently emerging clades and their relationships to one another.
Investigating Deep Phylogenetic Relationships among Cyanobacteria and Plastids by Small Subunit rRNA Sequence Analysis 1
TLDR
Small subunit rRNA sequence data were generated for 27 strains of cyanobacteria and incorporated into a phylogenetic analysis of 1,377 aligned sequence positions, finding all plastids cluster as a strongly supported monophyletic group arising near the root of the cyanobacterial line of descent.
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.
Evidence for a Cenozoic radiation of ferns in an angiosperm-dominated canopy
TLDR
New insight is provided into leptosporangiate diversification and the evolution of epiphytism by integrating a 400-taxon molecular dataset with an expanded set of fossil age constraints and finds evidence for a burst of fern diversification in the Cenozoic.
Phylogenetic Relationships and Evolution of Extant Horsetails, Equisetum, Based on Chloroplast DNA Sequence Data (rbcL and trnL‐F)
TLDR
The Equisetum crown group appears to have diversified in the early Cenozoic, whereas theEquisetaceae total group is estimated to have a Paleozoic origin, in remarkable agreement with current interpretations of the fossil record.
A molecular phylogeny of the fern family Pteridaceae: assessing overall relationships and the affinities of previously unsampled genera.
Marsileaceae Sporocarps and Spores from the Late Cretaceous of Georgia, U.S.A.
TLDR
Comparison of the fossil sporocarps with those of four extant species of Marsileaceae reveal marked similarity with Regnellidium diphyllum Lindm.
