description: Recent improvements in genome sequencing and assembly promise to generate high-quality reference genomes for many species. Yet the genome assembly process is still laborious and costly, requires substantial expertise, and is generally not scalable to the goals of multispecies scientific efforts. To democratise the training and assembly process, we implemented the latest version of the Vertebrate Genomes Project assembly pipeline in Galaxy, published earlier this year (Larivière et al. 2024). <br>
<br>
The automated pipeline performs de novo assembly based on PacBio HiFi reads, with optional extended graph phasing using Hi-C or parental data. It supports scaffolding using Bionano optical maps data and Hi-C via modular workflows. The workflows include quality control throughout the assembly process using GenomeScope, gfastats, Merqury, BUSCO, and Pretext.<br>
<br>
Within the Vertebrate Genome Project, these workflows have already been applied to de novo assemble genomes of over a hundred species, doubling the number of species reported in Larivière et al. 2024. We will present an overview of the new species assembled in Galaxy and what we learned from them. We will also present the updates to the published workflows and new workflows added to the VGP suite since its publication to assist with manual curation, including the integration of Treeval (Pointon, Eagles, and Sims, n.d.). <br>
<br>
The VGP's long-term goal is to use these workflows to generate high-quality, complete reference <br>
genomes for all of the roughly 70,000 extant vertebrate species, facilitating a new era of discovery <br>
across the life sciences. We will highlight how we use new developments in Planemo (Bray et al. 2023) <br>
to accelerate the production of genome assemblies through the command line.<br>
