Plant to Insect Horizontal Gene Transfer: Empowering Whiteflies

Horizontal gene transfer (HGT) is a well-documented evolutionary driving phenomenon in prokaryotes and eukaryotes, but its impact on the plant kingdom has remained elusive. A recent study provides compelling evidences, which support the idea that a plant-derived gene allows for the detoxification of plant defense metabolites in a polyphagous arthropod herbivore.
