Abstract This is a molecular phylogenetic study of the group formerly known as Dryadeae, based on DNA sequences from the internal transcribed spacers, ITS, of nuclear ribosomal DNA and the trnL intron and the trnL-trnF intergenic spacer of the chloroplast. A total of 1.9 kb, for 26 ingroup species, were analyzed using parsimony and model-based Bayesian inference. Some clades are well supported by both data sets: the ingroup, with Fallugia as the sister to the rest of the clade; Sieversia in a… 
Molecular phylogeny of Cotoneaster (Rosaceae) inferred from nuclear ITS and multiple chloroplast sequences
TLDR
P phylogenetic analyses were conducted to test infrageneric classifications of this genus using DNA sequence data from the nuclear ITS region and three chloroplast intergenic spacer regions and inferred that a deciduous habit, glabrous fruit, white anthers, erect and light pink petals, and white filaments are plesiomorphic character states in Cotoneaster.
The Phylogeny of Rosoideae (Rosaceae) Based on Sequences of the Internal Transcribed Spacers (ITS) of Nuclear Ribosomal DNA and the trnL/F Region of Chloroplast DNA
TLDR
The phylogeny of Rosoideae was investigated using 44 species using new sequence data from the chloroplast trnL/F region as well as an increased sample of species, and the monophyly of both Potentilleae and Sanguisorbeae is well supported.
The phylogenetic history of Selaginellaceae based on DNA sequences from the plastid and nucleus: extreme substitution rates and rate heterogeneity.
TLDR
A molecular data set from the nuclear 26S ribosomal DNA gene is developed, supporting new groupings not previously recognised on morphological grounds and indicating that high substitution rates might be widespread in all three genomes.
Phylogeny of korean rubus (rosaceae) based on its (nrDNA) and trnL/F intergenic region (cpdna)
TLDR
The phylogeny of the genusRubus in Korea using an internal transcribed spacer of the nuclear ribosomal DNA and a trnL-trnF (trnL/F) intergenic region of the chloroplast DNA showed that the occurrence of their morphological characters of simple and compound leaves was concurrent in KoreanRubus.
Phylogeny and classification of Rosaceae
TLDR
Strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies is found, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets.
Phylogenetic relationships within Cicuta (Apiaceae tribe Oenantheae) inferred from nuclear rDNA ITS and cpDNA sequence data
TLDR
Results of phylogenetic analyses of the nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) locus and the region bounded by the chloroplast genes psbI and trnK 5' exon are presented to determine taxonomic limits and relationships among these taxa, and to assess the taxonomic status of C. douglasii, a polyploid thought to be derived from C. maculata and C. virosa.
Allopolyploid evolution in Geinae (Colurieae: Rosaceae) – building reticulate species trees from bifurcating gene trees
TLDR
This extended study test if the reticulate phylogenetic hypothesis for Geinae can be maintained when additional sequences are added, and attempts to identify extant members of one of the inferred ancestral lineages of the allopolyploids.
Phylogeny and Biogeography of Dionysia (Primulaceae)
TLDR
Cladistic analyses using parsimony jackknifing and Bayesian inference were performed to elucidate phylogenetic relationships in the genus Dionysia, and the results strongly suggest that the sister species to the rest of genus DionYSia are DionysIA balsamea and D. hissarica.
Molecular phylogenetic systematics and biogeography of tribe Neillieae (Rosaceae) using DNA sequences of cpDNA, rDNA, and LEAFY.
A phylogeny of the tribe Neillieae (Rosaceae), which comprises Neillia, Stephanandra, and Physocarpus, was reconstructed based on nucleotide sequences of several regions of cpDNA, the ITS and ETS
Phylogeny of Korean Rubus (Rosaceae) based on the second intron of the LEAFY gene
TLDR
It was inferred that evolution proceeded from herbs to woody plants, compound leaf to simple leaf, and pink petal to white petal within Korean Rubus taxa, and the LEAFY and trnL/F combined phylogeny had similar topology with the Rubus classification based on morphological characteristics.

TLDR
The molecular phylogeny is compatible with some important independent characters and is useful for interpreting morphological and cytological evolution in Epilobium.
Documentation of reticulate evolution in peonies (Paeonia) using internal transcribed spacer sequences of nuclear ribosomal DNA: implications for biogeography and concerted evolution.
TLDR
Reconstruction of reticulate evolution with sequence data provides gene records for distributional histories of some of the parental species and demonstrates that the sequence data could be highly informative and accurate for detecting hybridization.
Phylogeny of the Coneflowers and Relatives (Heliantheae: Asteraceae) Based on Nuclear rDNA Internal Transcribed Spacer (ITS) Sequences and Chlorplast DNA Restriction Site Data
TLDR
Results of parsimony analysis of the rDNA dataset uphold the hypothesis from an earlier cpDNA restriction site study that Echinacea is not closely related to the other three genera of coneflowers and suggest that bioprospectors might usefully search among taxa of Zinniinae for bioactive substances similar to the immune stimulants of E Chinacea.
Systematic and evolutionary implications of rbcL sequence variation in Rosaceae
TLDR
RbcL-based phylogenies suggest that chromosome numbers are more reliable indicators of some generic alliances than the more commonly used fruit types and that the subfamily Maloideae may have descended from spiraeoid ancestors and the pome is derived from follicular or capsular fruit types.
Phylogenetic analysis ofPotentilla using DNA sequences of nuclear ribosomal internal transcribed spacers (ITS), and implications for the classification ofRosoideae (Rosaceae)
TLDR
It is suggested that in order to minimise nomenclatural change and to name only well supported clades, Potentilla should be split into several genera, while other previously recognised genera such as Duchesnea, Horkelia, andIvesia are best included inPotentilla.
Persistent nuclear ribosomal DNA sequence polymorphism in the Amelanchier agamic complex (Rosaceae).
Individual plants of several Amelanchier taxa contain many polymorphic nucleotide sites in the internal transcribed spacers (ITS) of nuclear ribosomal DNA (nrDNA). This polymorphism is unusual
Biogeography and Breeding System Evolution of the Woody Bencomia Alliance (Rosaceae) in Macaronesia Based on ITS Sequence Data
TLDR
The ITS tree demonstrates that dioecy evolved in the islands from a continental monoecious or gynomonecious ancestor and that there has been an increase in plant size and woodiness compared to continental relatives rather than the decrease suggested by previous workers.
Hybridization and Gene Flow Between Distantly Related Species of Rubus (Rosaceae): Evidence from Nuclear Ribosomal DNA Internal Transcribed Spacer Region Sequences
TLDR
Molecular data are used to examine natural hybridization between R. caesius and R. idaeus, a facultatively agamospermous tetraploid of subgenus Rubus (blackberries), and five putative hybrids from Sweden, and one individual each of R. maximiformis andR.
Phylogenetic relationships of Dipsacales based on rbcl sequences
TLDR
The genera of Caprifoliaceae do not form a monophyletic group and Symphoricarpos and Lonicera are related and are united with Valerianaceae and Dipsacaceae; Adoxa and Sambucus are directly linked and are possibly related to Viburnum.

TLDR
Cladistic analysis of amino acid sequence data, including evaluation of all equally or almost equally parsimonious cladograms, shows that much homoplasy (parallelisms and reversals) is present and that few or no well supported monophyletic groups of families can be demonstrated.
