    Abstract:
    Botta's pocket gopher (Thomomys bottae) is a common and widespread subterranean rodent of the North American west. The species has been of long interest to evolutionary biologists due to the phenotypic diversity across its range and unusual levels of variation in chromosome number and composition. Here, we present a high-quality reference genome from a male T. b. bottae individual captured in the San Francisco Bay Area. The assembly is comprised of 2,792 scaffolds, with a scaffold N50 value of 23.6 Mb and a BUSCO score of 91.0%. This genome helps fill a significant taxonomic sampling gap in rodent genome resources. With this reference genome, we envision new opportunities to investigate questions regarding the genomics of adaptation to the belowground niche. Further, we can begin to explore the impact of associated life history traits, such as limited dispersal and low population connectivity, on intraspecific genetic and phenotypic variation, genome evolution, speciation, and phylogenetic relationships across the Geomyoidea.
