英文摘要:Plants have developed complex and accurate defense mechanisms in the course of their long term co-evolution
with herbivorous insects. These typically involve the expression of specific defensive genes and subsequent production of
defensive substances that deter different insect feeding guilds. Generally,chewing insects cause more extensive tissue
damage and activate wound-signaling pathways whereas phloem-sucking insects induce pathogen-defense response
pathways. These different defensive responses require distinct recognition mechanisms and signaling pathways. We here
briefly analyze the defensive responses of plants to different insect feeding guilds.
