Genome Study Reveals How Antarctic Fish Survived Freezing Waters
Original: Jumping Genes and Antifreeze: New Genome Assembly Reveals How Antarctic Fish Conquered the Cold
A newly assembled genome of Antarctic notothenioid fish shows that transposable elements, or jumping genes, played a key role in the evolution of the fish's antifreeze glycoproteins, which allow it to live in ice-laden Southern Ocean waters. The findings shed light on how genome flexibility drove adaptation to extreme cold.
Why now: The new genome assembly offers fresh insight into the genetic mechanisms behind cold adaptation in Antarctic fish.
