Project

Optimisation of artificial reproduction in sterlet for the purpose of repatriation and conservation of genetic resources (QL24010011)

The aim is to identify the causes of ploidy abnormalities during artificial reproduction of sterlet to propose a procedure for reduction of these genetic anomalies. Next goal is to assess low oxygen tolerance and reproductive potent...

Prognostic importance of new genetically determinated markers in endometrial carcinoma (NS10272)

Abnormal DNA content in the nuclei of tumour cells, which usually arises from chromosomal aneuploidy, is a frequent finding in malignant tumours. Polyploidy is usually connected to prognostically unfavourable course of disease. Oncogenes are...

Genome duplication as an imperfect barrier in speciation? Evolutionary drivers and consequences of inter-ploidy introgression in natural populations (GA20-22783S)

derivative. Our genomic survey, however, demonstrated rampant inter-ploidy gene flow of ploidy barrier in five plant species and test the hypothesis that selection may promote inter-ploidy introgression. Firstly, we will i...

Relationships of ploidy level, genome and cell size in model polyploid fish with cytological and physiological impacts on conservation and culture. (GA523/08/0824)

Genome size in fishes is positively correlated to cell and nuclear size and volume. Increases in genome size due to shifts in ploidy level influence these cytological correlates causatively, with this effect persisting on both ancient polypl...
