Abstract
Tarim red deer (Cervus elaphus yarkandensis) is the only subspecies of red deer (of 22 subspecies) from Central Asia. This species is a desert dweller of the Tarim Basin of southern Xinjiang, China, and exhibits some unique adaptations to the dry and extreme hot climate. We report here the assembly of a Tarim red deer genome employing a 10X Genomics library, termed CEY_v1. Our genome consisted of 2.6 Gb with contig N50 and scaffold N50 of 275.5 Kb and 31.7 Mb, respectively. Around 96% of the assembled sequences were anchored onto 34 chromosomes based on the published high-quality red deer genetic linkage map. More than 94% BUSCOs complete genes (including 90.5% single and 3.6% duplicated ones) were detected in the CEY_v1 and 20,653 genes were annotated. The CEY_v1 is expected to contribute to comparative analysis of genome biology, to evolutionary studies within Cervidae, and to facilitating investigation of mechanisms underlying adaptation of this species to the extreme dry and hot climate.
Highlights
Background & SummaryCervidae is the second largest family in Ruminantia and consists of 56 species[1]
Little is known about the biology of this deer subspecies, it is likely to have evolved mechanisms to adapt to this hostile habitat
This paper reports a high quality Tarim red deer genome, which was generated through the combination of sequences created in the present study using the 10X Genomics GemCode platform with the previously published genetic linkage map data[27,28]; and is termed here CEY_v1
Summary
Cervidae is the second largest family in Ruminantia (second to Bovidae) and consists of 56 species[1]. Red deer (Cervus elaphus) is the most studied species in Cervidae and consists of 22 extant subspecies[9]. This paper reports a high quality Tarim red deer genome, which was generated through the combination of sequences created in the present study using the 10X Genomics GemCode platform with the previously published genetic linkage map data[27,28]; and is termed here CEY_v1. Almost 100% of the predicted genes (20,652) were annotated using biological databases We believe that this high-quality reference genome of CEY_v1 will provide a valuable resource for future studies to Tarim red deer in particular, and to Cervidae and even Ruminantia in general, as well as to shed light on the molecular mechanism of animal adaptation to extreme hostile environments
