Brassica napus Panache: A graph pangenome representing presence absence variation across ten B. napus genomes

Brassica napus is an economically important oil crop with significant levels of gene presence absence variation (PAV) between individuals, providing a source of genetic diversity that can be applied for crop improvement. Graph pangenomes are a new format for representing pangenomes and can be used to identify and explore PAV for use in breeding to accelerate crop improvement. Here we present a graph pangenome constructed from ten high-quality B. napus genome assemblies. The pangenome is hosted and visualized online with the pangenome analyzer with chromosomal exploration (Panache) tool. This public resource provides a comprehensive map of genome variability in B. napus that can be applied to accelerate the breeding of this important crop.
