show Abstracthide AbstractThe short-beaked echidna (Tachyglossus aculeatus) is a monotreme mammal found in Australia, which lays eggs. This assembly has been produced as part of the VGP Project and a BGI project on mammal evolution. Sequencing was conducted with PacBio long reads, Bionano optical maps, and 10X Genomics linked reads at Duke University and the Rockefeller University Vertebrate Genomes Lab led by Olivier Fedrigo, HiC by BGI, and Illumina sequencing. Genome assembly was conducted by Gregory Gedman and Giulio Formenti using the VGP 1.6 pipeline. The primary haplotype was assembled to chromosomes, whereas the alternate as contigs only. Genome coordination and funding was by Guojie Zhang and Erich Jarvis. The raw data and assembly are currently under a G10K-VGP publication embargo until removed from this description, following the G10K data use policy at the following URL: https://genome10k.soe.ucsc.edu/data-use-policies/
