Inferring basal relationships among vascular plants poses a major challenge to plant systematists. The divergence events that describe these relationships occurred long ago and considerable homoplasy has since accrued for both molecular and morphological characters. A potential solution is to examine phylogenetic analyses from multiple data sets. Here I present a new source of phylogenetic data for ferns and other pteridophytes. I sequenced the chloroplast gene atpB from 23 pteridophyte taxa… 
Phylogenetic relationships of land plants using mitochondrial small-subunit rDNA sequences.
This study represents the first use of mitochondrial 19S rDNA for phylogenetic purposes and it appears well-suited for examining intermediate to deep evolutionary relationships among embryophytes.
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
A new insight into the phylogeny of vascular cryptogams with special reference to Selaginella and Isoetes inferred from nuclear ITS/5.8S rDNA sequences
The MP phylogenetic tree identified Isoetes subinermis, I soetes durieui and Salvia microphylla as separate group among the studied taxa due to high sequence variation within these species through the time of evolution.
The chloroplast‐encoded atpB gene was sequenced from 33 strains representing 28 species of the colonial Volvocales to reexamine phylogenetic relationships as previously deduced by morphological data and rbcL gene sequence data, and Gonium was resolved as a robust monophyletic genus in the NJ and ML trees, and Eudorina elegans Ehrenberg represented a paraphyletic species positioned most basally within the Eudoros group.
Molecular phylogeny, character evolution, and biogeography of the grammitid fern genus Lellingeria (Polypodiaceae).
It is suggested that Lellingeria is monophyletic, with two clades that are easily characterized morphologically and biogeographically and a small clade previously considered in Terpsichore should be recognized as a new genus.
Multigene phylogeny of land plants with special reference to bryophytes and the earliest land plants.
A widely held view of land plant relationships places liverworts as the first branch of the land plant tree, whereas some molecular analyses and a cladistic study of morphological characters indicate
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
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.


rbcL gene sequences provide evidence for the evolutionary lineages of leptosporangiate ferns.
To compare competing classifications, DNA sequences of a chloroplast gene were obtained and phylogenetic trees were inferred by the neighbor-joining and the parsimony methods that provided insights concerning major general evolutionary trends in the leptosporangiate ferns.
Phylogenetics of seed plants : An analysis of nucleotide sequences from the plastid gene rbcL
Two exploratory parsimony analyses of DNA sequences from 475 and 499 species of seed plants, respectively, representing all major taxonomic groups indicate that rbcL sequence variation contains historical evidence appropriate for phylogenetic analysis at this taxonomic level of sampling.
Phylogenetic relationships of extant ferns based on evidence from morphology and rbcL sequences
The first cladistic analysis of extant ferns based on morphological characters is presented, showing the value of using both molecular and morphological data sets in combination as well as separately, and bootstrap support for the leptosporangiate fern clades is much greater using the combined data set than when either the morphological or the molecular data set is analyzed separately.
Phylogeny of the Ranunculaceae based on preliminary atp B, rbc L and 18S nuclear ribosomal DNA sequence data
The pattern of relationships based on sequence data supports the view that staminodia/petals and achenes have evolved independently several times within the Ranunculaceae.
Hierarchical Analysis of Allozymic and Morphometric Variation in a Montane Herb, Ipomopsis aggregata (Polemoniaceae)
Sixteen new sequences of the chloroplast gene rbcL were used to assess evolutionary relationships in Dennstaedtiaceae, and the following phylogenetic patterns were evident from maximum parsimony and maximum likelihood analyses.

The results indicate that rbcL sequences may be too divergent to test phylogenetic relationships among major groups of green plants and may be beneficial to include more taxa in subsequent analyses, but there are indications that historical extinctions will prevent adequate sampling of some groups, such as the bryophytes and fern allies.
Phylogeny of the Vittariaceae: Convergent Simplification Leads to a Polyphyletic Vittaria
A 1380 bp fragment of the chloroplast-encoded rbcL gene was amplified and sequenced from species repre- senting the genera and subgenera of the Vittariaceae, resulting in two most parsimonious trees which differ only in the position of the monotypic Ananthacorus.
Combining Data in Phylogenetic Systematics: An Empirical Approach Using Three Molecular Data Sets in the Solanaceae
Data from sequences of two chloroplast DNA genes, ndhV and rbcL, and from restriction site mapping studies of the entire chloroplane genome were analyzed for the same set of 17 species of Solanaceae and the outgroup Ipomoea, finding the "X = 12" dade is the most well-supported dade within the family.
Inter-familial relationships in the Ranunculidae based on molecular systematics
Cl cladistic analysis of the combined molecular data sets for all three genes provides important new data with which to test previous hypotheses of inter-familial relationships in the angiosperm subclass Ranunculidae.
A Molecular Assessment of Relationships Among Cryptic Species of Botrychium Subgenus Botrychium (Ophioglossaceae)
Phylogenetic relationships among 20 currently recognized species of Botrychium sub- genus Botrychium were investigated using nucleotide sequences from the plastid gene rbcL. Anal- ysis of eight
