Abstract/Contents:"Cyperus esculentus, commonly known as yellow nutsedge, is a perennial plant from the sedge family. While often considered a weedy sedge species, it also holds potential for cultivation, yielding various beneficial agronomic products. In this study, we conducted chromosome-level genome assembly and gene annotation of yellow nutsedge using PacBio HiFi long reads and Isoseq data. The final assembled genome is approximately 251.37 Mb, with an N50 value of 4.97 Mb and individual chromosomes ranging from 2.3 to 8.4 Mb. Additionally, the mitochondrial genome spans about 998 kb, and the chloroplast genome encompasses approximately 186 kb. Approximately 38% of the genome comprises repetitive sequences, totaling about 96.4 Mb. We observed that the chromosomes were generally arranged in diploid pairs, with sporadic instances of recombination and translocation, which adds complexity to the simple pairing of haploid chromosomes. Additionally, our investigation revealed 13,539 structural variations between the two haplotypes, accounting for 22.58 Mb of genomic differences between the two haplotypes. We also identified 18,479 functionally annotated protein-coding genes in the genome. Analysis of Gene Ontology (GO) terms and the Kyoto Encyclopedia of genes provide valuable insights into yellow nutsedge's adaptive mechanisms to diverse environments. The genomic information we have generated will serve as a valuable resource for researchers, enabling them to explore the unique evolution of plants with holocentric chromosomes compared to other plant species. It will also aid in developing novel herbicide targets to manage yellow nutsedge as a weed and strategies to improve the oil content in tubers of cultivated C. esculentus."
