Abstract
The ant Crematogaster osakensis (Hymenoptera: Formicidae: Myrmicinae) serves as a valuable model organism for investigating queen-specific traits, such as reproductive capacity and longevity, at the cellular and molecular levels. To support future research on queen traits using molecular techniques, including genome editing and multi-omics data analyses, we performed whole-genome sequencing of this species. The genome size of C. osakensis was estimated to be 284 Mb, with a heterozygosity of 0.26%. Annotation revealed the presence of 16,053 protein-coding genes. Furthermore, using the coding sequences annotated in this study, we reanalyzed previously obtained transcriptome data to identify highly expressed genes in the reproductive organs of queens and males. This data will contribute to a deeper understanding of the genetic mechanisms underlying reproductive strategies in ants.
期刊介绍：
DNA Research is an internationally peer-reviewed journal which aims at publishing papers of highest quality in broad aspects of DNA and genome-related research. Emphasis will be made on the following subjects: 1) Sequencing and characterization of genomes/important genomic regions, 2) Comprehensive analysis of the functions of genes, gene families and genomes, 3) Techniques and equipments useful for structural and functional analysis of genes, gene families and genomes, 4) Computer algorithms and/or their applications relevant to structural and functional analysis of genes and genomes. The journal also welcomes novel findings in other scientific disciplines related to genomes.
