  author={Svetlana B. Gontcharova and Elena Artyukova and Andrey A. Gontcharov},
  journal={Russian Journal of Genetics},
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… 

Phylogenetic relationships in the genus Primula L. (Primulaceae) inferred from the ITS region sequences of nuclear rDNA

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.

hylogenetic relationships between Sedum L . and related genera Crassulaceae ) based on ITS rDNA sequence comparisons yacheslav

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 tributes.

Molecular phylogeny and systematics of flowering plants of the family Crassulaceae DC

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.

Phylogenetic Relationships and Character Evolution of Rhodiola (Crassulaceae) based on Nuclear Ribosomal ITS and Plastid trnL-F and psbA-trnH Sequences

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.

ITS rDNA sequence comparisons resolve phylogenetic relationships in Orostachys subsection Appendiculatae (Crassulaceae)

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.

Molecular Phylogenetics of Crassulaceae

The major contributions to the phylogeny of Crassulaceae based on molecular data are reviewed, with emphasis on the major clades established in the family, the clades’ structure and polyphyly of some genera.

Linnaeus's folly – phylogeny, evolution and classification ofSedum(Crassulaceae) and Crassulaceae subfamily Sempervivoideae

This study presents a broadly sampled and dated molecular phylogeny of Sempervivoideae including 80% of all infrageneric taxa described in Sedum as well as most other genera of the subfamily and believes that combination of all 14 genera currently recognized in tribe Sedeae into Sedum might be the most stable solution of the “Sedum problem”.

Phylogenetic relationships among Orostachys subsection Orostachys species (Crassulaceae) based on nuclear and chloroplast DNA data

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.

The Conservation of Chloroplast Genome Structure and Improved Resolution of Infrafamilial Relationships of Crassulaceae

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.



The Phylogenetic Position of Eastern Asian Sedoideae (Crassulaceae) Inferred from Chloroplast and Nuclear DNA Sequences

Abstract The phylogenetic position of 74 taxa of Asian Sedoideae (Crassulaceae) was estimated based on analyses of the trnL-trnF intergenic spacer sequence of cpDNA and the ITS region, including the

Phylogeny and biogeography of Panax L. (the ginseng genus, araliaceae): inferences from ITS sequences of nuclear ribosomal DNA.

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.

Phylogenetic relationships in the Crassulaceae inferred from chloroplast DNA restriction-site variation.

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.

Phylogenetic relationships and evolution of Crassulaceae inferred from matK sequence data.

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.

Chromosomes of Crassulaceae from Japan and South Korea

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.

Origin of the Woody Macaronesian Sempervivoideae and the Phylogenetic Position of the East African Species of Aeonium

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.

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.
