Constants and variations in 69 diverse genomes of Arabidopsis thaliana

Pan-genome analysis uncovered substantial diversity in gene content that, together with the genome assemblies, will fuel future genetic research. Notably, 13,265 gene families (40% of the total) appear to comprise accessory genes as they are absent in at least one accession, including 10,420 that are absent from the reference genome (Fig. lb). Major impacts of widespread structural variation on gene expression and crop improvement in tomato.
