Abstract Cyperus iria is an aggressive weed of rice throughout the world.Until now, the reference genome of C.iria has not been published.Here, we completed the chromosome-level genome assembly of C.iria based on Illumina, Soccer - Clothing Junior Bottoms - Pants PacBio and Hi-C reads.
The assembled genome size of C.iria was 479.08 Mb with a contig N50 of 7.02 Mb.68 pseudochromosomes were produced using Hi-C scaffolding, accounting for 99.
65% of the assembled genome.The number of predicted protein-coding genes is 47,395, of which 93.26% were annotated, and 37.69% repetitive sequences were identified.Our study provided a valuable genomic resource for the molecular Coffee Substitutes biology research and the management of C.
