Endemism Patterns of Planthoppers (Fulgoroidea) in China [PDF]

open access: yesFrontiers in Ecology and Evolution, 2021
Studies on endemism are always of high interest in biogeography and contribute to better understanding of the evolution of species and making conservation plans. The present study aimed to investigate the endemism patterns of planthoppers in China by delimiting centers of endemism and areas of endemism.

Planthopper-Secreted Salivary Calmodulin Acts as an Effector for Defense Responses in Rice

open access: yesFrontiers in Plant Science, 2022
The brown planthopper (Nilaparvata lugens, BPH) and small brown planthopper (Laodelphax striatellus, SBPH) are major pests of rice (Oryza sativa) in Asia. These piercing-sucking insects secrete saliva into the host during feeding.

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

open access: yes, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Screening of Brown Planthopper Resistant miRNAs in Rice and Their Roles in Regulation of Brown Planthopper Fecundity

open access: yesRice Science, 2022
MicroRNAs (miRNAs) can participate in plant-insect interactions, which regulate plant defense networks. In this study, we analyzed the miRNA expression profiles of six rice varieties before and after brown planthopper (BPH)-feeding. We identified 45 differentially expressed miRNAs between BPH- susceptible and BPH-resistant rice varieties and 144 miRNAs
