High-quality chromosome scale genome assembly of Capsella bursa-pastoris

Capsella bursa-pastoris, a cosmopolitan weed of hybrid origin, is an emerging model object for the study of early consequences of polyploidy, being a fast growing annual and a close relative of Arabidopsis thaliana. The development of this model is hampered by the absence of a reference genome sequence. We present here a subgenome-resolved chromosome-scale assembly and a genetic map of a genome of Capsella bursa-pastoris. It shows that the subgenomes are mostly colinear, with no massive deletions, insertions or rearrangements in any of them.
