Whole-genome sequence of synthetically derived Brassica napus inbred cultivar Da-Ae.

ABSTRACT: Brassica napus, a globally important oilseed crop, is an allotetraploid hybrid species with two subgenomes originating from Brassica rapa and Brassica oleracea. The presence of two highly similar subgenomes has made the assembly of a complete draft genome challenging and has also resulted in natural homoeologous exchanges between the genomes, resulting in variations in gene copy number, which further complicates assigning sequences to correct chromosomes. Despite these challenges, high-quality draft genomes of this species have been released. Using third generation sequencing and assembly technologies, we generated a new genome assembly for the synthetic B. napus cultivar Da-Ae. Through the use of long reads, linked-reads, and Hi-C proximity data, we assembled a new draft genome that provi
