MicroRNA response in insect salivary glands to plant virus infection

Journal of Virology
Most arboviruses rely on insect vectors for transmission, with salivary glands serving as a critical gateway for viral spread to new hosts. MicroRNAs (miRNAs) are key regulators of gene expression, yet their roles in salivary glands during virus ...

Detection of Quantitative Trait Loci (QTLs) for Resistances to Small Brown Planthopper and Rice Stripe Virus in Rice Using Recombinant Inbred Lines

, 2013
Small brown planthopper (SBPH) and rice stripe virus (RSV) disease transmitted by SBPH cause serious damage to rice (Oryza sativa L.) in China. In the present study, we screened 312 rice accessions for resistance to SBPH.

Nitrogenous fertilizer reduces resistance but enhances tolerance to the brown planthopper in fast-growing, moderately resistant rice

The brown planthopper, Nilaparvata lugens (Stål), is a key challenge to rice production in Asia. Outbreaks of planthoppers are associated with excessive fertilizer applications; consequently, we examined planthopper interactions with susceptible ...

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

The brown planthopper (BPH; Nilaparvata lugens 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 ...

Chitin Deacetylase Gene Family Positively Regulates the Accumulation of Rice Stripe Virus in Laodelphax striatellus Fallén (Hemiptera: Delphacidae) Ovaries

Insects
Chitin deacetylase modifies chitin and has critical functions in the growth and development of insects; however, whether it has other roles is unclear.

Population of brown planthopper (Nilaparvata lugens) in paddy field at Kampung Dahlia Bachok, Kelantan / Siti Musliha Ismail

, 2016
The brown plant hopper (BPH) is a serious rice pest in Asia and one of the insect that gives the damage to the crop protection and can reduce the production at every year. The Small outbreaks were reported in Malaysia, such as in Malacca in 1939.
