[q-bio.GN] Reference genome assemblies are foundational resources across the biological sciences as they begin to expose the fundamental building blocks of each species and the molecular toolkits vital for adaptation and survival.
Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and understand whatever metabolic and genomic systems are in operation is important. Not only do we need to know how alien biota function, but also how they evolved – what differences and similarities they may have with the origin and evolution of life on Earth. Increasing in situ capabilities like this can allow much more preliminary analysis to be done on site – or back on Earth.
And once we have collected this information we will need to find a way to understand the totality of another world’s bioinformatics so as to understand how its biosphere and its component species operate, how they evolved, and how all of this can be compared to what happened on Earth. Is there one basic way for life to occur or many? Learning how to do this on our home world first is the best way to practice for the onslaught of alien genomics information we will eventually collect on the worlds we will one day visit.
The Earth BioGenome Project is an immense undertaking that is certain to provide lessons learned on how to contemplate doing a similar database construction for another inhabited world with a potentially different biochemistry. Or perhaps a familiar biochemistry for that matter.High-quality genomes enable insights into evolution, facilitate ecosystem monitoring and protection and conservation of species, access to new biomaterials and biomedicine, advances in agri- and aquaculture, and support planetary health.

The amount of information gathered from a species’ genome assembly is directly dependent on its quality. However, different sequencing technologies and software solutions generate a wide range of quality outcomes.
Here, the Earth BioGenome Project‘s Sequencing and Assembly committee, together with a large community of researchers performing eukaryote sequencing and assembly, outlines quality standards for a “reference” assembly and formulates recommendations to ensure these standards are met.
