GlaciaBase — Psychrophile & Cryophile Genomics Knowledgebase

Alba Tull
A dedicated psychrophile & cryophile genomics knowledgebase tracking species, genome assemblies, cold-adaptation genes, and sequencing runs across all known cold-adapted organisms. Part of the ExtremoDex extremophile ecosystem.

What makes GlaciaBase unique

While ExtremoDex catalogs all extremophile organisms as dex cards, GlaciaBase goes deep on psychrophiles & cryophiles — tracking individual species with temperature ranges, genome assemblies with reference status, cold-adaptation genes like CspA, antifreeze proteins, and DEAD-box RNA helicases, plus all associated sequencing runs from NCBI SRA and ENA.

Genome Assemblies

Tracking assembly completeness for psychrophile genomes. Most entries are bacteria or archaea, which have circular chromosomes and no telomeres, so a closed single-contig assembly is the completeness standard rather than telomere-to-telomere. Closed complete genomes: 0 / 0

Cold-Adaptation Genes

Psychrophiles possess remarkable molecular adaptations for surviving sub-zero temperatures. Key gene families include cold-shock proteins that stabilize RNA at low temperatures, antifreeze proteins that inhibit ice crystal growth, fatty acid desaturases that maintain membrane fluidity, and DEAD-box RNA helicases that ensure translation continues in the cold. These genes represent some of the most elegant molecular solutions in nature.
