Plants respond to physical injury, such as that caused by foraging insects, by synthesizing proteins that function in general defense and tissue repair. In tomato plants, one class of wound-responsive genes encodes proteinase inhibitor (pin) proteins shown to block insect feeding. Application of many different factors will induce or inhibit pin gene expression. Ethylene is required in the transduction pathway leading from injury, and ethylene and jasmonates act together to regulate pin gene expression during the wound response.
植物会对物理损伤做出反应，比如由觅食昆虫造成的损伤，通过合成在一般防御和组织修复中起作用的蛋白质。在番茄植株中，一类伤口响应基因编码蛋白酶抑制剂（pin）蛋白，已证明其能阻止昆虫进食。多种不同因素的作用会诱导或抑制pin基因的表达。乙烯是从损伤引发的信号转导途径中所必需的，并且乙烯和茉莉酸类物质共同作用，在伤口反应过程中调节pin基因的表达。
