The variability of brown planthopper (BPH) populations and diversity of the host rice germplasm provide an ideal model for exploring the genetic and molecular basis of insect-plant interactions. During the long-term evolutionary arms race, complicated feeding and defense strategies have developed in BPH and rice. Nine major BPH resistance genes have been cloned and the exploration of BPH resistance genes medicated mechanism against BPH shed a light on the molecular basis of the rice-BPH interaction. This short review provides an update on our current understanding of the genetic and molecular mechanism for rice resistance and BPH adaptation. Understanding the interactions between BPH and rice will provide novel insights for sustainable control of this pest.

褐飞虱（BPH）种群的变异性和宿主水稻种质的多样性为探索昆虫-植物相互作用的遗传和分子基础提供了理想的模型。在长期的进化军备竞赛中，在 BPH 和水稻中形成了复杂的饲养和防御策略。已经克隆了9个主要的BPH抗性基因，探索BPH抗性基因对BPH的作用机制揭示了水稻-BPH相互作用的分子基础。这篇简短的综述更新了我们目前对水稻抗性和 BPH 适应的遗传和分子机制的理解。了解 BPH 和水稻之间的相互作用将为可持续控制这种害虫提供新的见解。
