Although the combination of different genes in phylogenetic analyses is a promising approach, the methodology is not well established and analyses often suffer from inadequate, noncongruent taxon… Expand
Molecular Phylogeny of Conjugating Green Algae (Zygnemophyceae, Streptophyta) Inferred from SSU rDNA Sequence Comparisons
Nuclear-encoded SSU rDNA sequences have been obtained from 64 strains of conjugating green algae (Zygnemophyceae, Streptophyta, Viridiplantae). Molecular phylogenetic analyses of 90 SSU rDNA… Expand
In search of monophyletic taxa in the family Desmidiaceae (Zygnematophyceae, Viridiplantae): the genus Cosmarium.
Nuclear-encoded small subunit (SSU) rDNA, 1506 group I introns, and chloroplast rbcL genes were sequenced from 97 strains representing the largest desmid genus Cosmarium (45 spp.), its putative… Expand
Phylogeny and classification of Zygnematophyceae (Streptophyta): current state of affairs.
- A. Gontcharov
Conjugates (Zygnematophyceae) represent the most species-rich (ca. 4000 spp) algal lineage within the Streptophyta. Studies using various molecular markers have placed the class as one of the crown… Expand

Freshwater sponges include six extant families which belong to the suborder Spongillina (Porifera). The taxonomy of freshwater sponges is problematic and their phylogeny and evolution are not well… Expand
Phylogenetic relationships between Sedum L. and related genera (Crassulaceae) based on ITS rDNA sequence comparisons
Abstract 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… Expand
A study of conflict between molecular phylogeny and taxonomy in the Desmidiaceae (Streptophyta, Viridiplantae): analyses of 291 rbcL sequences.
Molecular phylogenetic analyses of 93 new and 198 non-redundant GenBank rbcL sequences of the family Desmidiaceae (Zygnematophyceae, Streptophyta) established 22 mostly highly supported clades, in… Expand
MOLECULAR PHYLOGENY OF STAURASTRUM MEYEN EX RALFS AND RELATED GENERA (ZYGNEMATOPHYCEAE, STREPTOPHYTA) BASED ON CODING AND NONCODING RDNA SEQUENCE COMPARISONS 1
Nuclear‐encoded small subunit rDNA, 1506 group I intron, and internal transcribed spacer sequences were obtained from 39 strains representing five core desmid genera, Staurastrum, Staurodesmus Teil.,… Expand
Unusual position of the genus Spirotaenia (Zygnematophyceae) among streptophytes revealed by SSU rDNA and rbcL sequence comparisons
Abstract Sexual reproduction by conjugation characterizes the genus Spirofaenia, and based on this character alone it has long been considered a member of the class Zygnematophyceae (Streptophyta).… Expand
Studies on subterranean amphipod crustaceans of Primory, Russia. Part 1. Three new species of the genus Pseudocrangonyx from springs and other groundwater habitats in far eastern Russia.
Three new species of the subterranean amphipod of the genus Pseudocrangonyx: P. tiunovi sp. nov., P. holsingeri sp. nov., P. sympatricus sp. nov. and male specimen for P. kseniae Sidorov, 2012 from… Expand
