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

Evaluation of Arabidopsis thaliana response to infection by Tomato spotted wilt virusand Groundnut ringspot virus [PDF]

Fitopatologia Brasileira, 2006
In Brazil the occurrence of different tospovirus species such as Tomato spotted wilt virus (TSWV) and Groundnut ringspot virus (GRSV) has been reported (De Avila et al., J. Gen. Virol. 74:153. 1993; De Avila et al., Arch. Virol. 128:211. 1993). Arabidopsis thaliana is currently the most studied plant and has had its genome completely sequenced since ...

Conservation agriculture practices in a peanut cropping system: Effects on pod yield and soil penetration resistance

Revista Brasileira de Ciência do Solo, 2023
Conservation agriculture principles applied to peanut can reduce soil erosion and production costs when cultivated in rotation with sugarcane. Still, the problem with soil compaction is the leading cause of skepticism about the efficacy of this practice.

Detection and partial characterization of an isolate of Groundnut ringspot virus in Solanum sessiliflorum [PDF]

Fitopatologia Brasileira, 2002
The cubiu (Solanum sessiliflorum) fruit, originating in the Amazon basin, is commonly used in that region for food, medicine, and cosmetics. In an experimental culture of cubiu, in order to evaluate its adaptation to conditions in the Northern region of the state of Rio de Janeiro, it was observed plants with mosaic symptoms.

Analysis of Tospovirus NSs Proteins in Suppression of Systemic Silencing. [PDF]

PLoS ONE, 2015
RNA silencing is a sequence-specific gene regulation mechanism that in plants also acts antiviral. In order to counteract antiviral RNA silencing, viruses have evolved RNA silencing suppressors (RSS).

Natural Occurrence of Groundnut ringspot virus on Soybean in South Africa

Plant Disease, 2002
Mechanically transmissible viruses were isolated from two soybean (Glycine max Merr.) plants from Rustenburg, Northwest Province and Greytown, KwaZulu-Natal, South Africa, respectively (2). Viruses were isolated by two serial local-lesion transmissions on Chenopodium quinoa.

A TaqMan real - Time RT - PCR assay for detection of Groundnut ringspot virus

Journal of Plant Pathology, 2016
Groundnut ringspot virus (GRSV) is a tospovirus species transmitted in a circulative propagative manner by several thrips species. Traditionally, GRSV is detected by enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR), so this paper describes a rapid diagnostic system for the reliable detection of GRSV

Evaluation of pyraclostrobin as a management tool of Groundnut ringspot virus in peanut crop

Phytoparasitica, 2020
Yield losses due to Groundnut ringspot virus – GRSV (genus Orthotospovirus) infection have been observed across major peanut (Arachis hypogaea L.) growing areas in Brazil. However, effective management systems capable of minimizing GRSV damage are not yet available.
