Silencing OsMAPK20-5 has different effects on rice pests in the field.
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.
