Chromosome-scale assembly of Capsella orientalis, maternal progenitor of cosmopolitan hybrid C. bursa-pastoris

The database contains a chromosome-scale genome assembly of Capsella orientalis, the maternal progenitor of a cosmopolitan allotetraploid C. bursa-pastoris. Using nanopore sequencing and data on chromatin contacts (HiC) we assembled the genome into eight pseudo-chromosomes with high contiguity, evidenced by a BUSCO completeness score of 99.3%. The genome annotation includes 27,889 protein-coding genes, with most exhibiting one-to-one orthology with Arabidopsis thaliana. These results establish a robust genomic resource for C. orientalis, facilitating future studies on polyploid evolution, gene regulation, and species divergence within Capsella.
