Abstract High-quality and complete reference genome assemblies are fundamental for the application of genomics to biology, disease, biodiversity conservation. However, such only available a few non-microbial species 1–4 . To address this issue, international Genome 10K (G10K) consortium 5,6 has worked over five-year period evaluate develop cost-effective methods assembling most accurate genomes date. Here we summarize these developments, introduce set quality standards, present lessons...

Abstract Interactive graphical genome browsers are essential tools in genomics, but they do not contain all the recent assemblies. We create Genome Archive (GenArk) collection of UCSC Browsers from NCBI Built on our established track hub system, this enables fast visualization annotations. Assemblies come with gene models, repeat masks, BLAT, and silico PCR. Users can add annotations via hubs custom tracks. bulk-import third-party resources, demonstrated TOGA Ensembl models for hundreds...

ABSTRACT Background Researchers are generating molecular data pertaining to the SARS-CoV-2 RNA genome and its proteins at an unprecedented rate during COVID-19 pandemic. As a result, there is critical need for rapid continuously updated access latest in format which all can be quickly cross-referenced compared. We adapted our browser visualization tool viral this purpose. Molecular data, curated from published studies or database submissions, mapped grouped together into “annotation tracks”...

Early-life exposure to maternal obesity or a calorically dense Western-style diet (WSD) is strongly associated with greater risk of metabolic diseases in offspring, most notably insulin resistance and dysfunction-associated steatotic liver disease (MASLD). Prior studies our well-characterized Japanese macaque model demonstrated that offspring dams fed WSD, even when weaned onto control (CTR) diet, had reductions skeletal muscle mitochondrial metabolism increased compared on CTR diet. In the...

Interactive graphical genome browsers are essential tools for biologists working with DNA sequences. Although tens of thousands new assemblies have become available over the last decade, accessibility is limited by work involved in manually creating and curating annotations. The results can push limits data storage infrastructure. To facilitate managing this increasing number assemblies, we created Genome Archive (GenArk) collection UCSC Browsers from hosted at NCBI(1). Built on our...
