The Snake That Took Guam Carries a Genomic Toolkit
A new reference genome reveals unusually abundant structural variation in brown tree snakes, including changes near immunity and smell-related genes.
Summary
A new reference genome reveals unusually abundant structural variation in brown tree snakes, including changes near immunity and smell-related genes.
Researchers analyzing brown tree snake genomes found more than 19,000 structural variants, with enrichment around genes involved in immune function and olfaction. The team argues that this standing variation may help the species adjust rapidly to unfamiliar environments and may help explain its destructive success after arriving on Guam. The genomic pattern supports an evolutionary interpretation; it does not prove which individual variants caused the invasion.
