C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]

open access: yesEuropean Journal of Entomology, 2006
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

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 ...

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

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.

Heterochromatin heteromorphism in Holhymenia rubiginosa (Heteroptera: Coreidae)

open access: yesEuropean Journal of Entomology, 2008
Heterochromatin is one of the most dynamic components in the genome of species. Previous studies on the heterochromatin content and distribution in Heteroptera (insects with holokinetic chromosomes) have shown that the species belonging to the family ...
