New Insights into the Regulatory Non-Coding RNAs Mediating Rice–Brown Planthopper Interactions

Le résumé fourni par la source

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