简介：昆虫长是最丰富的草食动物，并且植物发展了复杂机制对他们的攻击保卫。特别地，植物能察觉与昆虫herbivory联系的织物损坏的特定的模式。某植物种类能在昆虫察觉某些elicitors在喂期间进入创伤，并且很快激活一系列缠绕的发信号的小径安排各种各样的防御代谢物的生合成的口头的分泌物(OS)。激活Mitogen的蛋白质kinases(MAPK)，对所有优核质普通，涉及许多细胞的进程的组织，包括开发和压力回答。在植物，至少二MAPK，水杨酸导致酸的蛋白质kinase(SIPK)和导致创伤的蛋白质kinase(WIPK)，被伤害或昆虫OS很快激活；重要地，用在MAPK发信号损害的转基因或变异的植物的基因研究显示MAPK在调整植物激素的导致herbivory的动力学起关键作用，例如jasmonic酸，乙烯和水杨酸酸，和MAPK也为草食动物的transcriptional激活被要求防御代谢物的防卫相关的基因和累积。在这评论，我们在在植物抵抗理解MAPK的功能到昆虫草食动物总结最近的开发。
