The mitochondrial genome of the pleurocarpous moss Brachythecium rivulare has been sequenced and annotated. The genome consists of 104,460 base pairs and has approximately the same gene set and organization as other bryophyte mitogenomes. Whole mitochondrial genome comparison between B. rivulare and Physcomitrella patens, Tetraphis pellucida, Anomo...
The White Sea is a unique marine environment combining features of temperate and Arctic seas. The composition and abundance of photosynthetic picoeukaryotes (PPEs) were investigated in the land-fast ice of the White Sea, Russia, in March 2013 and 2014. High-throughput tag sequencing (Illumina MiSeq system) of the V4 region of the 18S rRNA gene was...
Picoalgae (defined as cells smaller than 2-3 μm) include members of diverse taxonomic groups. They are an important constituent of marine plankton and ice biota and play a significant ecological role in biogeochemical cycles. Despite their importance, the true extent of their diversity has only recently been uncovered by molecular surveys. The dive...
Stability of composition and sequence of genes was shown earlier in 13 mitochondrial genomes of mosses (Rensing, S. A., et al. (2008) Science, 319, 64-69). It is of interest to study the evolution of mitochondrial genomes not only at the gene level, but also on the level of nucleotide sequences. To do this, we have constructed a "nucleotide pangeno...
The structure of the intergenic spacer 1 (IGS1) of the ribosomal operon from 12 species of Schistidium mosses was studied. In the IGS1 sequences of these species, three conserved regions and two areas of GCand A-enriched repeats were identified. All of the studied mosses have a conserved pyrimidine-enriched motif at the 5′-end of IGS1. Species-spec...
Phylogeny of Schistidium (Bryophyta, Grimmiaceae) was studied by comparing the nucleotide sequences of internal transcribed spacers ITS1-2 of nuclear
rDNA and the trnT-trnD region of chloroplast DNA. Phylogenetic trees constructed based on nuclear and chloroplast sequences were consistent, comprising
a basal grade and two large clades. Morphologica...
ITS sequences of taxonomically difficult complexes in the genus Dicranum, D. fuscescens–D. flexicaule and D. brevifolium–D. acutifolium–D. pseudacutifolium, are analyzed. Type specimens of D. pseudacutifolium are found to be poorly developed specimens of D. flexicaule and therefore the former name is synonymizedwith the latter. At the same time, se...
A study of ITS1 of 28 specimens of eight species of Schistidium from well-separated populations in Russia and northwest Europe revealed that there are very big differences between species (up to 16 substitutions and 256 indels), whereas within the species differences in DNA there are very few (none to four substitutions and none to six indels). The...
