Glucosylation prevents plant defense activation in phloem-feeding insects.

Osnat Malka, Michael L A E Easson, Christian Paetz, Monika Götz, Michael Reichelt, Beate Stein, Katrin Luck, Aleksa Stanišić, Ksenia Juravel, Diego Santos-Garcia, Lilach L Mondaca, Simon Springate, John Colvin, Stephan Winter, Jonathan Gershenzon, Shai Morin, Daniel G Vassão,

The metabolic adaptations by which phloem-feeding insects counteract plant defense compounds are poorly known. Two-component plant defenses, such as glucosinolates, consist of a glucosylated protoxin that is activated by a glycoside hydrolase upon plant damage. Phloem-feeding herbivores are not generally believed to be negatively impacted by two-component defenses due to ... Read more >>
