Tospoviruses Induce Small Interfering RNAs Targeting Viral Sequences and Endogenous Transcripts in Solanaceous Plants [PDF]

Pathogens, 2022
Tospoviruses infect numerous crop species worldwide, causing significant losses throughout the supply chain. As a defence mechanism, plants use RNA interference (RNAi) to generate virus-derived small-interfering RNAs (vsiRNAs), which target viral ...

Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

Groundnut Bud Necrosis Virus Modulates the Expression of Innate Immune, Endocytosis, and Cuticle Development-Associated Genes to Circulate and Propagate in Its Vector, Thrips palmi [PDF]

Frontiers in Microbiology, 2022
Thrips palmi (Thysanoptera: Thripidae) is the predominant tospovirus vector in Asia-Pacific region. It transmits economically damaging groundnut bud necrosis virus (GBNV, family Tospoviridae) in a persistent propagative manner.

TSWV Infection Differentially Reshapes the Symbiotic Microbiome of Two Frankliniella Thrips Species [PDF]

Viruses
Vectoring tomato spotted wilt virus (TSWV) by two well-known thrips species, Frankliniella occidentalis Pergande and F. intonsa Trybom (Thysanoptera: Thripidae), is facilitated in different ways.

Five questions on the cell-to-cell movement of Orthotospoviruses [PDF]

BBA Advances
Plant viruses employ Movement proteins (MP) for their cell to cell spread through plasmodesmata (PD). MP modifies the PD and increases its size exclusion limit (SEL).

Tospoviruses (Family Bunyaviridae, Genus Tospovirus)

EDIS, 2005
Viruses in the genus Tospovirus cause significant worldwide crop losses. The genus name is derived from the name of its first member, Tomato spotted wilt virus (TSWV). Initially observed in Australia in 1915, the spotted wilt disease of tomato was later

Optimized use of UV-B light to suppress Western flower thrips in controlled environment tomato crops. [PDF]

Pest Manag Sci
Visual representation of study into the use of UV‐B light to simultaneously attract and suppress Western flower thrips in controlled environment crops. Abstract BACKGROUND LEDs (light emitting diodes) are being deployed in controlled environment crop production systems to boost crop growth, manipulate pest behavior, improve performance of natural ...

Antiviral RISC mainly targets viral mRNA but not genomic RNA of tospovirus. [PDF]

PLoS Pathogens, 2021
Antiviral RNA silencing/interference (RNAi) of negative-strand (-) RNA plant viruses (NSVs) has been studied less than for single-stranded, positive-sense (+)RNA plant viruses.

Tospovirus-Resistant Tomato Varieties for Southern Florida

EDIS, 2017
Authors describe performance of Tospovirus-resistant tomato varieties under commercial production settings in Dade County, FL. Virus resistance has become important for this area since the emergence of two new tomato-infecting tospoviruses. Knowledge of

N Protein of Tomato Spotted Wilt Virus Proven to Be Antagonistic Against Tomato Yellow Leaf Curl Virus in Nicotiana benthamiana. [PDF]

Mol Plant Pathol
N protein of tomato spotted wilt virus reduces the expression of the key protein V1 of tomato yellow leaf curl virus in co‐transfected Nicotiana benthamiana, through affecting host energy metabolism‐related pathways. ABSTRACT Two phylogenetically unrelated viruses transmitted by different insect vectors, tomato spotted wilt virus (TSWV) and tomato ...
