Title: New insights on the influence of genomic structural variation on crossover occurrence

Abstract:
In Eucaryotes, meiotic crossovers are generally not distributed evenly across chromosomes. We evaluate the recombination landscape of rice (Oryza sativa L.) by generating a highly saturated genetic linkage map, obtained from 2,000 F2 recombinants sequenced by short reads at 2-3x. We then compare genomic features from the parental genomes sequenced by long reads. Using these data, we examine how crossover occurrence is related with different genomic and epigenomic features.
