The Pathogenesis-Related Protein 4b Induced by Rice Stripe Virus Enhances Host's Antiviral Defence. [PDF]

Mol Plant Pathol
OsPR4b is induced by RSV to inhibit viral infection via regulating RNA metabolism and cell wall reinforcement, while its knockdown modulates NAC/MYB/ERF/WRKY family genes and enhances viral accumulation. ABSTRACT Rice stripe virus (RSV) causes rice stripe disease, which poses a serious threat to rice production.

Adaptation by the Brown Planthopper to Resistant Rice: A Test of Female-Derived Virulence and the Role of Yeast-like Symbionts

Insects, 2021
The adaptation by planthoppers to feed and develop on resistant rice is a challenge for pest management in Asia. We conducted a series of manipulative experiments with the brown planthopper (Nilaparvata lugens (Stål)) on the resistant rice variety IR62 ...

RNA-Sequencing Reveals Differentially Expressed Rice Genes Functionally Associated with Defense against BPH and WBPH in RILs Derived from a Cross between RP2068 and TN1

Rice, 2021
Background Rice is staple food for over two billion people. Planthoppers like BPH and WBPH occur together in most of rice growing regions across Asia and cause extensive yield loss by feeding and transmission of disease-causing viruses.

Direct and Indirect Effects of Planting Density, Nitrogenous Fertilizer and Host Plant Resistance on Rice Herbivores and Their Natural Enemies

Agriculture, 2022
In rice ecosystems, seeding densities can be adjusted to compensate for lower nitrogen levels that reduce GHG emissions, or to increase farm profitability.

Development of Molecular-Based Species Identification and Optimization of Reaction Conditions for Molecular Diagnosis of Three Major Asian Planthoppers (Hemiptera: Delphacidae)

Insects, 2023
Asian planthoppers (Hemiptera: Delphacidae) that include brown planthoppers (BPH, Nilaparvata lugens, Stål), white-backed planthoppers (WBPH, Sogatella furcifera, Horváth), and small brown planthoppers (SBPH, Laodelphax striatellus, Fallén) are the ...

Mediation of volatiles on the intra- and interspecific relationships between Angrus nilaparvatae Pang & Wang and Cyrtorhinus lividipennis (Reuter)

浙江大学学报. 农业与生命科学版, 2002
Mediation of volatiles in the relationships between Angrus nilaparvatae Pang & Wang and Cyrtorhinus lividipennis (Reuter) were studied using rice variety TN1. The results showed that A. nilaparvatae and C.

Using Wolbachia to control rice planthopper populations: progress and challenges

Frontiers in Microbiology, 2023
Wolbachia have been developed as a tool for protecting humans from mosquito populations and mosquito-borne diseases. The success of using Wolbachia relies on the facts that Wolbachia are maternally transmitted and that Wolbachia-induced cytoplasmic ...

The crystal structure of Cry78Aa from Bacillus thuringiensis provides insights into its insecticidal activity

Communications Biology, 2022
The crystal structure of the Bacillus thuringiensis protein Cry78Aa shows it consists of a C-terminal β-pore forming domain and an N-terminal trefoil domain and suggests a mechanism underlying the function of Cry78Aa against rice planthoppers.

Cuticular Hydrocarbon Plasticity in Three Rice Planthopper Species [PDF]

International Journal of Molecular Sciences, 2021
Insect cuticular hydrocarbons (CHCs) are organic compounds of the surface lipid layer, which function as a barrier against water loss and xenobiotic penetration, while also serving as chemical signals. Plasticity of CHC profiles can vary depending upon numerous biological and environmental factors.

Effect of transgenic Bt rice on dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps

浙江大学学报. 农业与生命科学版, 2003
Effects of TT9-3 and TT9-4, which are two homozygous strains of transgenic Bt rice, on the dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps were evaluated in the field.
