The Lysak Lab
We investigate genome evolution across the plant kingdom at different levels of complexity:
- DNA sequences (NGS-based genome analysis)
- Chromosomes (chromosome rearrangements, karyotype evolution)
- Genomes (genome collinearity, polyploidy)
- Species (speciation, phylogenomics)
Genome evolution in crucifers (Brassicaceae) is our leading research theme. We are analyzing the incidence, mechanisms and rate of chromosome rearrangements, sequence structure of chromosome breakpoints, modes of centromere shift and elimination, evolution of repetitive sequences, and reconstructing ancestral genomes. We are testing causal links between whole-genome duplication events, karyotypic variation and species radiations.
