Their genomes are large and generally variable in sizes and feature a high abundance of repetitive DNA sequences. This has hampered the assembly of grasshopper genomes to the chromosome level. Here we present a chromosome-level reference genome for the club-legged grasshopper (Gomphocerus sibiricus, Acrididae: Gomphocerinae) using PacBio HiFi long-read and Hi-C sequencing technologies. In male haploid cells, the species has a chromosome set of n = 9 with an X0 sex-determination system, characterized by an absence of a Y chromosome. Our assembly spans 9.57 Gb in total, with 8.87 Gb organized into 9 chromosomes-8 autosomes and the X chromosome. The final assembly has a scaffold N50 value of 1.58 Gb, covers 96.7% single copy Insecta orthologs, and contains 42,665 predicted protein-coding genes and 43,385 mRNA transcripts. We compiled a curated, nonredundant, species-specific repeat library and used it to annotate repetitive DNA, covering 81.69% of the genome, mostly DNA transposons, long-interspersed nuclear element and long-terminal repeat retrotransposons. The genome of the club-legged grasshopper shows high degree of synteny with the locusts Schistocerca gregaria and Locusta migratoria, and the analysis strongly indicates 3 autosome-autosome centric fusions in Gomphocerinae. The genome offers a valuable resource for grasshopper genomics and for exploring the genetic basis of a transspecies color polymorphism.", "doi": "10.1093/g3journal/jkaf231", "pmid": "41029998", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC12693501"}, {"db": "pii", "key": "8269502"}, {"db": "BioProject", "key": "PRJNA1250961"}, {"db": "GENBANK", "key": "JBPBLO000000000"}, {"db": "SRA", "key": "SRX29045381"}, {"db": "SRA", "key": "SRX29045382"}, {"db": "SRA", "key": "SRX29045386"}, {"db": "SRA", "key": "SRX29045393"}, {"db": "SRA", "key": "SRX29073929"}, {"db": "SRA", "key": "SRX29073928"}, {"db": "SRA", "key": "SRX29045383"}, {"db": "SRA", "key": "SRX29045385"}, {"db": "figshare", "key": "10.6084/m9.figshare.29476994"}, {"db": "figshare", "key": "10.6084/m9.figshare.29148779"}, {"db": "figshare", "key": "10.6084/m9.figshare.29148836"}, {"db": "figshare", "key": "10.6084/m9.figshare.29148746"}], "notes": [], "created": "2026-09-23T13:19:18.537Z", "modified": "2026-09-23T13:19:18.652Z"}]}
