Molecular polymorphisms that underlie trait variation in crops: Lessons learned from soybean

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Genetic variation within a germplasm is important in crop improvement, providing a foundation for breeders to develop new varieties. Traits of agronomic and economic importance are often mapped to identify the genetic basis of observed phenotypes, oftentimes using quantitative trait locus (QTL) analysis.

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Response of Leafhopper Community Structure and Diversity to Fragmented Habitat in a Rocky Karst Desertification Area, Guizhou, China

open access: yesInsects
Guizhou Province is located in the karst area of southern China, where rocky desertification is severe, and habitat fragmentation is prominent. Leafhoppers are widely distributed, with over 2000 recognized species found in China.

A new species of the sharpshooter genus Cardioscarta (Hemiptera: Cicadellidae) from Bolivia and Peru

open access: yesZoologia (Curitiba), 2016
The South American sharpshooter genus Cardioscarta Melichar, 1932 comprises six species. In this paper we describe and illustrate C. splendida sp. nov. based on a specimen from Bolivia (male holotype deposited in DZUP).

Phylogeographic and Ecological Insights Into the Evolutionary History of the Grass‐ and Sedge‐Specializing Deltocephalinae Leafhoppers

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Phylogenetic reconstructions and morphological analysis robustly support the monophyletic status of tribes specializing in grass and sedge habitats. Grass‐ and sedge‐specializing groups diverged from nonspecializing groups around 95.85 million years ago (Ma) during the Cretaceous period, preceding the origin of grasses and sedges (76–88 Ma), indicating

Infection Characteristics of Rice Stripe Mosaic Virus in the Body of the Vector Leafhoppers

open access: yesFrontiers in Microbiology, 2019
Rice stripe mosaic virus (RSMV), a novel species of Cytorhabdovirus, is transmitted by the leafhopper Recilia dorsalis in a persistent-propagative manner.

Bottom–up and top–down diversification: asymmetric processes over space and time

open access: yesOikos, Volume 2026, Issue 1, January 2026.
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversification, and less on top–down processes through enemy‐associated differentiation.

Rice Yellow Stunt Nucleorhabdovirus Matrix Protein Mediates Viral Axonal Transport in the Central Nervous System of Its Insect Vector

open access: yesFrontiers in Microbiology, 2019
Persistently transmitted plant viruses encounter multiple membrane and tissue barriers in the process of completing their infection routes within their insect vectors.
