Water Bear Genome Uncovers Novel Stress-Tolerant Proteins

JAMA. 2016;316(17):1755. doi:10.1001/jama.2016.15523

In a recent study published in Nature Communications, researchers sequenced the genome of a species of small aquatic animal that can tolerate almost complete dehydration with the goal of uncovering unique proteins that mitigate stress-induced cellular damage.

The species, called Ramazzottius varieornatus, is one of the most stress-tolerant species of tardigrades (aka water bears). Only a small proportion (1.2%) of R varieornatus genes were acquired from other species through horizontal gene transfer.
