A comparison of similarity indices between 64 durum wheat cultivars calculated using pedigree analysis and RAPD method showed a correspondence between these two approaches to estimation of genetic diversity. The associations between the results of RAPD clustering and coefficients of parentage (χ2 test) and the coefficient of correlation between similarity(More)
Allelic diversity at five gliadin-coding gene loci has been studied in the most important spring durum wheat cultivars released in Russia and former Soviet republics in the 20th century (66 cultivars). Seven, 5, 8, 13, and 2 allelic variants of blocks of gliadin components controlled by the loci Gli-A1 d , Gli-B1 d , Gli-A2 d , Gli-B2 d , and Gli-B5 d ,(More)
Polymorphism and inheritance of wheat storage protein, gliadin, of durum (macaroni) and carthlicum wheats have been studied. Analysis of gliadin in 78 cultivars and in F2 seeds of intercultivar crosses of durum wheat revealed three different chromosome 1A-encoded blocks of components similar to those found in common wheat (GLD1A2, GLD1A18, GLD1A19). Most of(More)
The gliadin composition of 78 spring durum wheat varieties has been studied by one-dimensional (Al-lactate,pH 3.1) and two-dimensional (first dimension, Al-lactate,pH 3.1; second dimension, sodium dodecyl sulfate-polyacrylamide gel) electrophoresis. Analysis of hybrids has shown that all components of the α zone of gliadin spectra are inherited together as(More)
The sequences that encode the main functional glucosyltransferase domain of sucrose synthase genes have been identified for the first time in 14 species of the genus Malus and related species of the family Rosaceae, and their polymorphism was investigated. Single nucleotide substitutions leading to amino acid substitutions in the protein sequence, including(More)
Recent phylogenomic analyses have revolutionized our view of eukaryote evolution by revealing unexpected relationships between and within the eukaryotic supergroups. However, for several groups of uncultivable protists, only the ribosomal RNA genes and a handful of proteins are available, often leading to unresolved evolutionary relationships. A striking(More)
Molecular markers based on retrotransposon insertions are widely used for various applications including phylogenetic analysis. Multiple cases were described where retrotransposon-based markers, namely sequence-specific amplification polymorphism (SSAP), were superior to other marker types in resolving the phylogenetic relationships due to their higher(More)
Spumochlamys perforata n. sp. and Spumochlamys bryora n. sp. were isolated and described from dry epiphytic moss. The morphology and ultrastructure of both species clearly demonstrate that they belong to the genus Spumochlamys (family Microchlamyiidae). They differ from its only described member, Spumochlamys iliensis (as well as from species of(More)
