Overview

Randomized trial reveals genetic adaptations in Jonah’s icefish, implying insights into evolution and cold environments.

Key Points

  • This study aims to present a chromosome-level genome assembly of Jonah's icefish and explore its genetic adaptations.
  • Conducted genome assembly integrating Illumina, PacBio HiFi, and Hi-C sequencing data.
  • Achieved 1.27 Gb genome comprising 24 chromosomes with 96.8% anchoring efficiency.
  • Performed genome annotation identifying 31,777 protein-coding genes.
  • Genome assembly shows 42.14% repetitive elements.
  • High genomic collinearity with related species supports assembly accuracy.
  • Provides a reference genome for studying cold adaptation and trait loss in Antarctic icefish.
