Silencing Suppressor Protein p26 of Areca Palm Velarivirus 1 (APV1) Interacts With SGS3 and Promotes Its Degradation Via the Ubiquitination Pathway

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
APV1‐encoded p26 protein is a multifunctional VSR that suppresses RNA silencing and blocks the systemic spread of silencing signals. p26 interacts with host SGS3, a key component of the plant antiviral silencing pathway, and targets SGS3 for accelerated degradation via the ubiquitination pathway.

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

Elucidating R‐gene‐mediated resistance to wheat dwarf virus in Triticum aestivum genotypes

Annals of Applied Biology, Volume 188, Issue 3, Page 947-961, May 2026.
This study investigates R‐gene‐mediated resistance to wheat dwarf virus (WDV) among different wheat genotypes. Following inoculation with Psammotettix alienus (leafhoppers) and the subsequent appearance of characteristic symptoms such as yellowing and dwarfing, phenotypic responses were evaluated alongside molecular analyses, including quantification ...

Infectivity, effects on helper viruses and whitefly transmission of the deltasatellites associated with sweepoviruses (genus Begomovirus, family Geminiviridae) [PDF]

Scientific Reports, 2016
AbstractBegomoviruses (family Geminiviridae) are whitefly-transmitted viruses with single-stranded DNA genomes that are frequently associated with DNA satellites. These satellites include non-coding satellites, for which the name deltasatellites has been proposed. Although the first deltasatellite was identified in the late 1990s, little is known about
