Earliness is a critical agronomic trait that enables plants to avoid adverse weather conditions during the late growing season or at harvest. In wheat, earliness is controlled by at least three distinct mechanisms: vernalization requirement, photoperiod sensitivity, and a mechanism independent of the first two, so called, earliness per se. In this...
Familial dysbetalipoproteinemia (FD) is a highly atherogenic, prevalent genetically based lipid disorder. About 10% of FD patients have rare APOE variants associated with autosomal dominant FD. However, there are insufficient data on the relationship between rare APOE variants and FD. Genetic data from 4720 subjects were used to identify rare APOE...
Genetic overdiagnosis of long QT syndrome (LQTS) becomes a critical concern due to the high clinical significance of DNA diagnosis. Current guidelines for LQTS genetic testing recommend a limited scope and strict referral based on the Schwartz score. Nevertheless, LQTS may be underdiagnosed in patients with borderline phenotypes. We aimed to evalua...

In the Triticeae tribe, several subgenomes (St, J, V and others) were described, and a subgenome-specific molecular marker development is an actual branch of studies. Non-transcribed spacers (NTS) of 5S rDNA are perspective to create species-specific or genome-specific molecular markers in closely related organisms. Early, the 5S rDNA NTS based CAP...
Key message
The first-time generation of hexaploid triticale plants harbouring variable panels of novel mutations in gene families involved in starch biosynthesis has been achieved by the subgenome-independent multiplexed CRISPR/Cas9-mediated editing.
Satellite repeats are a significant component of the genome of Triticeae and play a crucial role in the speciation. They are a valuable tool for studying these processes. Pseudoroegneria species play a special role among grasses, as they are considered putative donors of the St-genome in many polyploid species. The aim of this study was to compare...
