Subject: „Drivers of polyploid genome evolution: repetitive DNA dynamics and chromosome rearrangements”
Unit of the project realization: Faculty of Natural Sciences; Institute of Biology, Biotechnology and Environmental Protection – University of Silesia in Katowice
Unit realizing the PhD student education: Doctoral School at the University of Silesia in Katowice
The project will focus on rDNA evolution and organization in Amaranthus using molecular, cytogenetic, bioinformatic, and phylogenetic approaches to understand post-polyploidization genome evolution, including sequence variation and chromosomal localization. It also investigates karyotype evolution and chromosome number changes, including chromosome fusions and dysploidy, using oligo-labeling probes, fluorescent in situ hybridisation, and comparative cytogenetic analyses.
Research will be carried out in the frame of the project „Drivers of polyploid genome evolution: repetitive DNA dynamics and chromosome rearrangements” (number of the project 2025/59/B/NZ8/00852), financed from NCN under management of dr hab. Bożena Kolano, prof. UŚ
