Аннотация: The cytogenetic study of Abies sibirica seed progenies in declining fir stands of West Sayan High Mountains has been carried out. The increased amount of chromosome and genome mutations, pathologies of mitotic cycle and cells with micronuclei were found at studying. The revealed irregularities may be the result of a long-term exposure to extreme environmental factors and probably reflect the high degree of disturbance of the ecosystem in this region.

    The effect of radionuclide and heavy metal contamination of the Yenisei River on cytogenetics of aquatic plant Elodea canadensis
/ A. Bolsunovsky [et al.] // Radioprotection. - 2009. - Vol. 44, Is. 5. - P83-88, DOI 10.1051/radiopro/20095021 . - ISSN 0033-8451

Аннотация: The study was done to determine concentrations of radionuclides and heavy metals and to evaluate the frequency of chromosomal aberrations in samples of Elodea canadensis, a submerged plant, collected in different parts of the Yenisei River. Samples were collected in the area subjected to radioactive impact of theMining-and-Chemical Combine (MCC) at Zheleznogorsk and in the control areas, upstream of the MCC. The investigations showed that Elodea biomass in the area affected by MCC operation contained a long inventory of artificial radionuclides typical of the MCC discharges. Upstream of the MCC, in the control sampling areas, the sediments and the Elodea biomass contained only one artificial radionuclide - 137Cs. Thus, the exposure doses to Elodea shoots and roots upstream of the MCC are small (not more than 8 ?Gy/d) and the main contribution to them is made by natural radionuclides. At the MCC discharge site (the village of Atamanovo) and downstream of it, the total dose rate increases almost an order of magnitude, reaching its maximal values - 72 ?Gy/d for Elodea shoots and 58 ? Gy/d for roots. Cytogenetic investigations of Elodea roots showed that at the MCC discharge site (the village of Atamanovo) and downstream of it the occurrence of chromosomal aberrations in ana-telophase and metaphase cells of Elodea was considerably higher than in the control area. It is highly probable that this simultaneous dramatic increase in the total exposure rate and the occurrence of chromosomal aberrations in Elodea is associated with the radiation factor. It is suggested that Elodea is affected not only by the radiation factor but also by the chemical factor - toxicity of heavy metals. В© 2009 EDP Sciences.

    Somaclonal variation of haploid in vitro tissue culture obtained from Siberian larch (Larix sibirica Ledeb.) megagametophytes for whole genome de novo sequencing

Аннотация: The objective of this study was to obtain a genetically stable haploid in vitro-derived line from Siberian larch (Larix sibirica Ledeb.) using megagametophyte explants, which then could be used for different molecular genetic studies, including whole genome de novo sequencing. However, cytogenetic analysis and genotyping of 11 microsatellite loci showed high levels of genomic instability and a high frequency of mutation in the obtained megagametophyte-derived callus cultures. All cultures contained new mutations in one or more microsatellite loci.
