Identification and analysis of microRNAs responsible for brown planthopper resistance in BPH14 and BPH15 pyramiding rice

Liang Hu, Dabing Yang, Hongbo Wang, Xueshu Du et autres

BACKGROUND: Rice farming faces a significant challenge from the brown planthopper (BPH), a destructive pest that threatens crop yields. Developing BPH-resistant rice varieties is critical for ensuring food security. The pyramiding of BPH resistance genes, BPH14 and BPH15, has proven effective in …

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

Liang Hu, Yan Wu, Wenjun Zha, Lei Zhou et autres

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, …

The Roles of Phytohormones in Plant Defense Mechanisms Against the Brown Planthopper

Huiying Wang, Wenjun Zha, An Huang, Yan Wu et autres

Stål) is the most significant insect pest compromising rice production globally. Phytohormones, which are small organic compounds produced by plants, play a crucial role in regulating plant growth and development. Nevertheless, extensive research has established that phytohormones are essential in modulating plant …

Transcriptome analysis of biotic and abiotic stress mediated by the suction of brown planthopper in two rice cultivars

Changyan Li, Wenjun Zha, Jianyu Wang, Yan Wu et autres

RH (Rathu Heenati), an indica rice cultivar from Sri Lanka, is highly resistant to several different biotypes of brown planthopper (Nilaparvata lugens Stål, BPH). In contrast, another indica rice cultivar, TN1 (Taichung Native 1), is highly susceptible to all biotypes of BPH. …
