Chromosome-Level Genome Assembly and Annotation of purple nutsedge (Cyperus rotundus Cyperaceae).

ABSTRACT: Cyperus rotundus, one of the most aggressive weeds worldwide, demonstrates significant resistance to conventional control strategies. This species causes yield losses ranging from 20% to 90% in both agricultural and horticultural crops, posing a substantial threat to agricultural ecosystems. In this study, we present a chromosome-level genome assembly and annotation of C. rotundus. The haplotypic assembly spans approximately 293 Mb in length, with a high contig N50 of 5.49 Mb, a GC content of 36%, and a BUSCO score of 93.4%. A total of 94.03% (275.55 Mb) of the contigs were successfully mapped onto 54 chromosomes. Repetitive sequences constitute 44.78% of the genome. We predicted 23,280 protein-coding genes, 97% (52,439) of which were functionally annotated. The reference genome will serve
