丝裂原活化蛋白激酶(MAPKs)在植物生长发育和对生物和非生物胁迫的适应性反应中发挥着重要作用。最近，水稻MAPK基因OsMAPK20-5被报道通过抑制食草动物诱导的乙烯和一氧化氮信号来保护水稻免受自毒。在此背景下，我们观察到沉默OsMAPK20-5增加了稻纵卷叶蛾引起的卷叶率和稻瘟病菌引起的稻瘟病的严重程度，但降低了纹枯病引起的纹枯病的严重程度。这些结果表明，沉默OsMAPK20-5对田间水稻害虫有不同的影响，这些差异对植物抗病策略的进化和开发具有重要意义。
Mitogen-activated protein kinases (MAPKs) play important roles in plant development and adaptive responses to biotic and abiotic stresses. Recently, a rice MAPK gene, OsMAPK20-5, has been reported to protect rice plants against autotoxicity by suppressing herbivore-induced ethylene and nitric oxide signaling. In this context, we observed that silencing OsMAPK20-5 increased the percentage of leaf roll caused by leaf folder Cnaphalocrocis medinalis and the severity of rice blast caused by Magnaporthe grisea but decreased the severity of sheath blight caused by Rhizoctonia solani. These findings show that silencing OsMAPK20-5 has different effects on rice pests in the field, and these differences have important implications for the evolution and exploitation of resistance strategies in plants.
