Chaos in Cartan foliations.

Chaotic foliations generalize Devaney's concept of chaos for dynamical systems. The property of a foliation to be chaotic is transversal, i.e, depends on the structure of the leaf space of the foliation.

[Molecular marker mapping of the gene resistant to common bunt transferred from Aegilops cylindrica into bread wheat].

Introgression lines 5/55-91 and 378/2000 of bread wheat contain the gene of resistance to Tilletia caries (DC.) Tul. transferred from Aegilops cylindrica Host.

[Molecular-genetic analysis of wheat (T. aestivum L.) genome with introgression of Ae. cylindrica Host genetic elements].

Wheat-aegilops hybrid plants Triticum aestivum L. (2n = 42) x Aegilops cylindrica Host (2n = 28) were investigated with using microsatellite markers. In two BC1F9 lines some genome modifications connected with losing DNA fragments of initial variety or appearing of Aegilops genome elements were detected.

[Detection of the introgression of genome elements of the Aegilops cylindrica host. into the Triticum aestivum L. genome by ISSR and SSR analysis].

To reveal sites of the donor genome in wheat crossed with Aegilops cylindrica, which acquired conferred resistance to fungal diseases, a comparative analysis of introgressive and parental forms was conducted. Two systems of PCR analysis, ISSR and SSR-PCR, were employed. Upon use of 7 ISSR primers in genotypes of 30 individual plants BC1 F9 belonging to lines 5/55-91 and 5/20-91, 19 ISSR loci were revealed and assigned to introgressive fragments of Aegilops cylindrica genome in Triticum aestivum.

[Investigation of molecular-genetic heterogeneity of clematis plants (Clematis L.) obtained by organogenesis and somatic embryogenesis in vitro].

Genome variability of in vitro micropropagated Clematis plants was established. The optimum concentrations of BAP and zeatin in the culture medium regulating in vitro morphogenetic processes in clematis explants cv. Serenada Kryma were determined.
