A pangenome and pantranscriptome of hexaploid oat.

ABSTRACT: Oat grain is a traditional human food that is rich in dietary fibre and contributes to improved human health^1,2. Interest in the crop has surged in recent years owing to its use as the basis for plant-based milk analogues³. Oat is an allohexaploid with a large, repeat-rich genome that was shaped by subgenome exchanges over evolutionary timescales⁴. In contrast to many other cereal species, genomic research in oat is still at an early stage, and surveys of structural genome diversity and gene expression variability are scarce. Here we present annotated chromosome-scale sequence assemblies of 33 wild and domesticated oat lines, along with an atlas of gene expression across 6 tissues of different developmental stages in 23 of these lines. We construct an atlas
