Molecular Mechanisms of Insect Resistance in Rice and Their Application in Sustainable Pest Management

Simple Summary Insect pests are a major cause of yield loss in rice, and breeding insect-resistant varieties is an effective way to reduce reliance on chemical pesticides. This review summarizes recent progress in understanding how rice plants resist insect pests such as the brown planthopper, rice gall midge, and white-backed planthopper. We highlight key resistance genes and explain how rice recognizes insect attacks and activates defense responses using plant hormone signaling pathways, including the salicylic acid and jasmonic acid pathways. The review also covers modern breeding techniques like molecular markers, gene pyramiding, and transgenic technologies, along with the significance of wild rice species as resistance sources. Overall, this work aims to support the development of durable, insect-resistant rice varieties and promote sustainable rice production amid changing pest pressures and climate conditions.
