Capsella rubella is a predominantly self-fertilizing species that recently evolved from an outcrossing ancestor closely related to C. grandiflora. As a self-compatible lineage with a relatively recent origin, C. rubella is a valuable model for investigating the genomic consequences of the transition from outcrossing to selfing, including changes in recombination, heterozygosity, genome size, transposable element accumulation, and epigenomic regulation.

The C. rubella RAM v1.1 genome was assembled using PacBio HiFi long reads and Omni-C chromatin conformation capture data. Draft contigs were generated from HiFi reads, filtered to remove contamination and redundant haplotypic sequence, and then scaffolded with Omni-C data to produce a chromosome-scale, near-gapless assembly. Compared with previously available C. rubella genome resources, this assembly is substantially more contiguous and more complete, especially across repetitive genomic regions that are important for studying transposable elements, centromeres, and genome architecture.

This page summarizes available genome information, annotation resources, and downloadable data for the C. rubella dataset. This page provides a hub for access to the C. rubella data available so far, via data portals, JBrowse genome browsers, and gene/locus search pages.
