Nucleotide sequences of the nuclear rDNA ITS regions were determined in 20 species of the subfamily Sedoideae (Crassulaceae). The phylogenetic relationships of these species with other members of the subfamily, occurring mainly in Southeast Asia, were analyzed. It was shown that the genus Orostachys was not monophyletic; its type subsection was significantly included into the clade of the genus Hylotelephium. Synapomorphic substitutions and indels, specific for the subsection Orostachys, were… Expand

Phylogenetic relationships between Sedum L. and related genera (Crassulaceae) based on ITS rDNA sequence comparisons
TLDR
The highly polyphyletic nature of Sedum and its relatives corroborated in this study using a large taxon set, calls for re-evaluation of the genus concept in the family Crassulaceae and the tribe Sedeae in particular. Expand
Phylogenetic relationships in the genus Primula L. (Primulaceae) inferred from the ITS region sequences of nuclear rDNA
TLDR
In this analysis species of the Russian flora and the flora of adjacent territories were studied for the first time and clarified the taxomic structure of the genus Primula and confirmed the entity of some of its sections; but not the subgenera sensu J.Richards. Expand
hylogenetic relationships between Sedum L . and related genera Crassulaceae ) based on ITS rDNA sequence comparisons yacheslav
Sedum is the most species-rich and taxonomically complex member of the family Crassulaceae. The genus comprises ca. 420 species, which display notable diversity and homoplasy of growth forms,Expand
Molecular phylogeny and systematics of flowering plants of the family Crassulaceae DC
TLDR
It is shown that the traditional taxonomic structure of Crassulaceae contradicts pattern of phylogenetic relationships between its members, and it is stressed that homoplasy of morphological characters does not allow to use them to reconstruct relationships between crassulacean taxa even at the low taxonomic levels. Expand
Phylogenetic Relationships and Character Evolution of Rhodiola (Crassulaceae) based on Nuclear Ribosomal ITS and Plastid trnL-F and psbA-trnH Sequences
TLDR
The phylogenetic relationships within Rhodiola remain poorly understood largely because of difficulties in collecting samples and specimens, but it is suggested that Rhodiola and Pseudosedum form a well-supported clade. Expand
ITS rDNA sequence comparisons resolve phylogenetic relationships in Orostachys subsection Appendiculatae (Crassulaceae)
TLDR
The first molecular phylogeny of Orostachys subsection Appendiculatae is presented based on a large number of ITS rDNA sequences representing most currently recognized members of the subsection and utilizing secondary structure information. Expand
Molecular Phylogenetics of Crassulaceae
Crassulaceae is the most species-rich family (ca. 1400 spp.) of the Saxifragales and the majority of its members are succulents. Great diversity of morphology, cytology and habit complicatesExpand
Phylogenetic relationships among Orostachys subsection Orostachys species (Crassulaceae) based on nuclear and chloroplast DNA data
TLDR
The data suggest that the current concepts of O. malacophylla, O. maximowiczii, and O. gorovoii are incompatible with the differentiation at the cpDNA level, and a high level of similarity of ITS rDNA sequences between the subsection members suggests their relatively recent and rapid divergence from a common ancestor. Expand
The Conservation of Chloroplast Genome Structure and Improved Resolution of Infrafamilial Relationships of Crassulaceae
TLDR
Nine newly sequenced chloroplast genomes are reported, which comprise several key lineages of Crassulaceae and enhance the understanding of the infrafamilial relationships and the conservation of chloroplowlast genomes within CrASSulaceae. Expand
Orostachys spinosa (Crassulaceae) origin and diversification: East Asia or South Siberian Mountains? Chloroplast DNA data
TLDR
The results indicated that the species could have originated in mountains of Southern Siberia (Altai), which was colonized independently from O. thyrsiflora which has a largely overlapping distribution in this area. Expand

TLDR
The Himalayas and central and western China are the current centers of diversity of the ginseng genus and the low ITS sequence divergence and a close relationship among species in that region suggest that rapid evolutionary radiation may have created such a diversity of Panax in the Himalaya and in central and eastern China. Expand
Phylogenetic relationships in the Crassulaceae inferred from chloroplast DNA restriction-site variation.
TLDR
There is very strong support for a basal division of the Crassulaceae, which separates the monophyletic subfamily Crassuloideae from all other taxa, and four of the six traditionally recognized subfamilies are indicated to be polyphyletic. Expand
Phylogenetic relationships and evolution of Crassulaceae inferred from matK sequence data.
TLDR
A southern African origin of the family is suggested, with subsequent dispersal northward into the Mediterranean region and two separate lineages of European Crassulaceae subsequently dispersed to North America and underwent substantial diversification. Expand
Chromosomes of Crassulaceae from Japan and South Korea
TLDR
Rough measurements of nuclear volume support the conclusion that members of two species complexes differ in the types of chromosome change predominating in their evolution, polyploidy in S. Aizoon and structural chromosomal rearrangements inS. Expand
Origin of the Woody Macaronesian Sempervivoideae and the Phylogenetic Position of the East African Species of Aeonium
TLDR
The extremely close genetic ties among the woody and branched (sub)shrubs indicate that, when compared to the other species of the genus, the wooded, African Aeonium species are not the sister group of the Macaronesian Sempervivoideae and substantiate the view that an ancestor of A. leucoblepharum recently migrated from the Canary Islands to East Africa and Arabia through long distance dispersal.

TLDR
This latest revision of the classification and geography of the Dicotyledons is necessitated by the plethora of new information that has become available about the classification of the Angiospermae, especially in the currently popular approaches of cladistic, particulate, and molecular taxonomy.
