Chloroplast rbcL sequences of 60 species of Polystichum sensu lato (s.l.), including 23 new sequences from southwest China, were used to assess the phylogenetic relationships within the genus. On the basis of estimated evolution rate of rbcL gene and the genetic distance data that passed relative-rate tests, we further estimated the divergence times between some clades of the genus. The phylogenetic relationships were inferred using the neighborjoining and maximum-parsimony methods, both… 
Origin of Hawaiian Polystichum (Dryopteridaceae) in the context of a world phylogeny.
TLDR
The origin of the Hawaiian species of Polystichum is the result of multiple migrations to the islands, rather than single migrations yielding nearly all the local diversity as in the angiosperms, which provides a modern test of the premise that propagule vagility has a central role in determining pattern of evolution.
Molecular Phylogeny of the Polystichoid Ferns in Asia Based on Rbcl Sequences
TLDR
Morphologically, once-pinnate leaf dissection and reticulate venation appear to be ancestral in the polystichoid ferns.
Inclusion of the Eastern Asia endemic genus Sorolepidium in Polystichum (Dryopteridaceae): Evidence from the chloroplast rbcL gene and morphological characteristics
TLDR
Molecular data establish that Sorolepidium is deeply nested within the large genus Polystichum and has a close relationship with P. duthiei and P. lachenense in the model-based analyses.
Using a multilocus phylogeny to test morphology-based classifications of Polystichum (Dryopteridaceae), one of the largest fern genera
TLDR
DNA sequences of five plastid loci of 177 accessions representing ca.
Phylogeny and divergence of Chinese Angiopteridaceae based on chloroplast DNA sequence data (rbcL and trnL-F)
TLDR
The phylogenetic trees revealed that all species of Angiopteris and ArchangiopterIS formed a monophyletic group with strong statistical support, but the relationship between the two genera remained unresolved based on individual sequence analysis.
Phylogeny and biogeography of exindusiate Andean Polystichum (Dryopteridaceae).
TLDR
The monophyletic exindusiate Andean Polystichum lineage diverged from a Mexican lineage in the middle Miocene and diversified in the central Andes before dispersing northward, corresponding with episodes of uplift in the tropical Andes.
Phylogeny and divergence time estimation of cheilostome bryozoans based on mitochodrial 16S rRNA sequences
TLDR
The mitochondrial 16S rDNA sequences of 40 species of cheilostome bryozoans including those of 24 species newly determined were used to reconstruct the phylogenetic tree using neighboringjoining and maximumparsimony methods and show that the molecular phylogeny of the higher taxonomic groups is mostly in conflict with the morphologybased phylogenetic trees.
Phylogenetic Positions of the Enigmatic Asiatic Fern Genera Diplaziopsis and Rhachidosorus from Analyses of Four Plastid Genes
TLDR
Four plastid gene sequence analyses supported a sister relationship between Diplaziopsis, Rhachidosorus and the North American Homalosorus, the monophyletic group of the newly-examined genera is an early diverging lineage of Woodsiaceae, and far away from athyrioid ferns.

Major evolutionary events in the origin and diversification of the fern genus Polystichum (Dryopteridaceae).
TLDR
Examining rbcL sequences and morphological characters from 55 fern taxa suggests that the common ancestor of Polystichum s.s.l. and Phanerophlebia had evolved the common features of the alliance, including ciliate petiole-base scales, once-pinnate fronds, ultimate segments with scarious tips, peltate indusia, and microscales.
Testing relative evolutionary rates and estimating divergence times among six genera of Rhizophoraceae using cpDNA and nrDNA sequences
The molecular phylogenetic trees of 10 species representing 6 genera of the family Rhizophoraceae have been constructed using the sequences of chloroplast genesmatK andrbcL as well as the ITS regions
Chloroplast and nuclear gene sequences indicate late Pennsylvanian time for the last common ancestor of extant seed plants.
TLDR
Phylogenetic analyses of nucleotide sequences indicated that the earliest divergence of extant seed plants is likely represented by a split between conifer-cycad and angiosperm lineages, which implies a substantially more recent ancestor of all extant plant plants than suggested by some theories of plant evolution.
Sensitivity of the relative-rate test to taxonomic sampling.
TLDR
It is shown that comparing large numbers of species significantly improves the power of the relative-rate test, and results are more accurate when phylogenetic relationships between the investigated sequences are taken into account.
