The brown planthopper (Nilaparvata lugens Stål, BPH) is a destructive pest of rice. Non-coding RNAs (ncRNAs) regulate the defense mechanisms in rice and adaptive strategies BPHs. In rice, ncRNAs modulate key resistance pathways such as jasmonic acid biosynthesis, flavonoid production, phenylpropanoid metabolism, which increases BPH resistance. BPHs, processes reproduction, wing polyphenism, facilitate adaptation virulence. Cross-kingdom interactions between BPHs reveal dynamic molecular interplay that underpins this pest–host relationship.

Introduction The brown planthopper (BPH) poses a significant threat to rice production in Asia. use of resistant varieties has been effective managing this pest. However, the adaptability BPH led emergence virulent populations, such as biotype Y BPH. YHY15 rice, which carries resistance gene Bph15 , exhibits notable 1 but is susceptible Limited information exists regarding how plants defend against populations with varying levels virulence. Methods In study, we integrated miRNA and mRNA expression profiling analyses study differential responses both avirulent (biotype 1) Y) Results demonstrated rapid response infestation, transcriptional changes occurring within 6 hours. Y-responsive genes were notably enriched photosynthetic processes. Accordingly, infestation induced more intense responses, affecting expression, defenserelated metabolic pathways, phytohormone signaling, multiple transcription factors. Additionally, callose deposition was enhanced BPH-infested seedlings. Discussion These findings provide comprehensive insights into defense mechanisms BPH, may potentially guide development insect-resistant varieties.
