Recombination landscape divergence between populations is marked by larger low-recombining regions in domesticated rye
Ontology highlight
ABSTRACT: The analysis of genome-wide genotyping-by-sequencing data for 266 accessions of the German ex situ genebank focused on the genomic landscapes of recombination in a collection of 916 rye (Secale cereale) individuals. By analysing population structure among individuals of different domestication status and geographic origin, we detected high levels of admixture, reflecting the reproductive biology of a self-incompatible, wind-pollinating grass species. We then analysed patterns of recombination in overlapping subpopulations, which revealed substantial variation in the physical size of LR regions, with a tendency for larger LR regions in domesticated subpopulations.
