Herbivore-induced early defense signaling and its evolution in Nicotiana

Insect feeding often induces early defense signaling in plants that activates a cascade of anti-herbivore defenses, protecting the plants from further attack. However, defense responses can also reduce the plant`s ability to survive due to physiological trade-offs. Thus plants need to evolve a robust signaling network that regulates these herbivore-induced defenses. Phylogenomic analysis of the genes involved in herbivore induced transcriptomic responses in Nicotiana showed that genome multiplication likely played an important role in shaping the evolution of early defense signaling in plants.
