A revision of chromosome II (CD) mapping in Chironomus plumosus (Linnaeus, 1758) group (Diptera, Chironomidae)

open access: yesComparative Cytogenetics, 2012
A revision of the main and alternative banding sequences in chromosome II (CD) has been made for all 14 species of the Chironomus plumosus (Linnaeus, 1758) group. A new version of mapping has been suggested for 10 out of 18 banding sequences of arm C and

Using the synthetic form RS5 to obtain new introgressive lines of common wheat

open access: yesВавиловский журнал генетики и селекции, 2021
The use of the gene pool of wild relatives, which have a significant reserve of genetic diversity, is of immediate interest for breeding common wheat. The creation and use of synthetic forms as “bridges” is an effective method of transferring valuable ...

Karyotype analysis of Quasipaa spinosa David, 1875 (Anura, Dicroglossidae) with conventional cytogenetic techniques [PDF]

open access: yesComparative Cytogenetics
The current study analyzed the chromosomal karyotype of Quasipaa spinosa David, 1875 from Hunan Province, China. The karyotype, C-banding, BrdU-banding pattern were characterized using direct preparation of bone-marrow cells and hemocyte cultures.

Microevolutionary differentiation of cereal tetraploid species by formation of recombinant genomes

open access: yesВавиловский журнал генетики и селекции, 2016
The process of microevolutionary differentiation of cereals by formation of recombinant genomes was studied in dynamics (F6–F17) with tetraploid wheat-rye amphidiploids as examples. Evidence that joint growing of tetra ploid amphidiploids having a common

Alien introgressions and chromosomal rearrangements do not affect the activity of gliadin-coding genes in hybrid lines of Triticum aestivum L. × Aegilops columnaris Zhuk

open access: yesВавиловский журнал генетики и селекции, 2018
Using chromosome C-banding and electrophoresis of grain storage proteins, gliadins, 17 Triticum aestivumAegilops columnaris lines with substitutions of chromosomes of homoeologous groups 1 and 6 were examined.

Sequential Q- and C-band staining of pig chromosomes, and some comments on C-band polymorphism and C-band technique [PDF]

open access: yesHereditas, 2008
Sequential Q- and C-band staining of chromosomes of domestic pig (Sus scrofa domestica) is presented, probably for the first time, and the C-band pattern is described. Large C-bands were usually found on pair Nos. 1, 13, 15, 16, and 18, but in some animals large C-bands were found on other pairs, too.
