Annotation

Comparative chromosome painting (CCP) enables the identification of large homeologous chromosome regions shared among two or more species. In plants, the technique is only feasible in crucifers (Brassicaceae). This project will further our knowledge on the extent of cross-species chromosomal colinearity, scenarios and rates of karyotypic alterations within the plant kingdom. Karyotype evolution will be analyzed in relation to the Ancestral Crucifer Karyotype (ACK) and ancestral genomic blocks. For the first time, CCP will be applied to unveil the extent of infrageneric and intraspecific karyotypic variation. Putting CCP data into a molecular phylogenetic framework will significantly expedite our understanding of the role of the chromosomal reshuffling in plant diversification and speciation.
