Project description:The project aimed to characterize the collagen type I (COL1) sequences from Pleistocene Macrauchenia sp. and Toxodon sp. bone samples, and by comparison with existing COL1 sequences available from genomic sources establish the phylogenetic position of both extinct species. In order to resolve their phylogenetic position, COL1 was extracted from two Toxodon (samples MLP201204, MACN201212, York12, York13) and two Macrauchenia (samples MLP201212, MACN201202, York14, York15). In addition, modern and Pleistocene COL1 was extracted from additional species currently not present in available databases (Mylodon darwinii, Cyclopes didactylus, Hippopotamus amphibius, Tapirus terrestris) or from species for which COL1 sequences are available (Equus sp., Oryceropus afer). All extractions were performed at BioArCh, University of York (UK). Analyses took place on Bruker maXis HD (Macrauchenia sp., Toxodon sp., Equus sp.) and Thermo Scientific Hybrid Quadruopole-Orbitrap (Macrauchenia sp., Toxodon sp., Mylodon darwinii, Cyclopes didactylus, Hippopotamus amphibius, Tapirus terrestris, Oryceropus afer) platforms.

Project description:Choloepus didactylus (Linnaeus's two-toed sloth) genome, mChoDid1, sequence data
Project description:Sloths, a group of xenarthran mammals comprised of 6 distinct species, have been the focus of much physiological animal research due to their extremely slow metabolisms, deliberate movements, and their status as a species relatively unchanged for over 26 million years. However, despite all the effort aimed at understanding these unique characteristics, the sloth genome remains largely unexplored. Due to the link between genetics and observed traits, such an investigation could potentially lead to insights regarding the genetic basis of sloth behaviors and characteristics. In this exploratory investigation, we performed genomic and transcriptomic analysis of a female Choloepus didactylus (Linnaeus’s Two-Toed Sloth). Transcriptome analysis of peripheral blood mononuclear cells (PBMCs) showed gene expression levels in two-toed sloths, which are conjectured to be responsible for many of the unique features of two-toed sloths and opens a path towards future exploratory research into specific gene and protein functions tied to the unique characteristics of the sloth species.
