Sumario:Tamias sibiricus is regarded as one predominant scatter-hoarder that stores their food items both in small scattered caches and underground larder-hoards. This unique behavior, though providing essential seed dispersal services for many plant species worldwide, relies highly on accurate spatial memory and acute sense of olfaction. Here, we assembled a chromosome-scale genome of T. sibiricus using Illumina sequencing, PacBio sequencing and chromosome structure capture technique. The genome was 2.64 Gb in size with scaffold N50 length of 172.61 Mb. A total of 2.59 Gb genome data was anchored and orientated onto 19 chromosomes (ranging from 28.70 to 222.90 Mb) with a mounting rate of up to 98.03%. Meanwhile, 25,311 protein-coding genes were predicted with an average gene length of 32,936 bp, and 94.73% of these genes were functionally annotated. This reference genome will be a valuable resource for in-depth studies on basic biological possess and environmental adaptation of the Siberian chipmunk, as well as promoting comparative genomic analyses with other species within Rodentia.
