Whole-genome sequencing of the ant Crematogaster osakensis (Hymenoptera: Formicidae: Myrmicinae).
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.

Research summary
The paper investigates the genetic mechanisms underlying reproductive strategies in ants, specifically focusing on queen-specific traits related to longevity. This research is relevant as it explores the cellular and molecular aspects of longevity through the lens of reproductive capacity in a model organism.
