Description
| - Karyotyp a další chromozómové znaky u korušky smrduté, Osmerus eperplanus byly vyšetřeny pomocí konvenčních a molekulárních cytogenetických metod. Diploidní počet chromozómů byl 2n = 56 a karyotyp složen z 5 párů metacentrických, 9 párů submetacenrických a 14 páru subtelo až akrocentrických chromozómů. Místa hlavních ribosomálních genů byla nalezena na kratším raměnku největšího metacentrického páru chromozómů. Zde byl popsán velmi komplikovaný systém inverzí měnící detailní strujturu a stavbu tohoto raménka. Vyštření pomocí telomerické sondy neodhalilo ITS. Místa 5S rDNA genů byla lokalizována na 4 párech subtelocentrických chromozómů. Cytotyxonomické srovnání výsledků s voluminozní literaturou o cytotaxonomii lososovitých potvrdilo, že tyto skupiny nejsou evolučně příbuzné. (cs)
- Karyotype and cytogenetic haracteristics of European smelt Osinerits eperlanus were investigated using different staining techniques (sequential Ag-, CMA3 and DAPI banding) and PRINS to detect 5S rDNA and telomeric sites. The diploid chromosome number was invariably 2n = 56 and karyotype composed of 5pairs of metacentrics, 9 pairs of ubtelocentrics and 14 pairs of subtelo- to acrocentrics. The nucleolar organizer regions (NORs) were detected in the short (p) arms of the largest metacentric pair of chromosomes No. 1. Sequential banding (Giemsa-, AgNO3 and CMA3 stainings) revealed NOR sites corresponding to achromatic regions but not associated with CMA(3)-positive blocks of heterochromatin located on either side of NORs. A complex inversion system was hypothesized to be involved in the origin of the observed variation but analysis with telomeric PRINS and PNA-FISH did not reveal any nterstitial Telomeric Sites (ITS). The 5S ribosomal sites as revealed by PRINS were found to be invariably lo...
