Occurrence of Groundnut ringspot virus on Brazilian peanut crops
Journal of General Plant Pathology, 2014A high incidence of plants with mosaic, chlorotic spots, ringspots, necrosis, smaller leaves, and stunting was observed on peanut crops (Arachis hypogaea L.) in Itapolis, Sao Paulo State, Brazil. Transmission electron microscope examination of thin sections of infected leaves revealed the presence of spheroidal particles, ca.

Three viruses belonging to different plant virus genera were found associated with Phalaenopsis plants showing symptoms of mild chlorotic spots, mild mosaic and dark green islands with light green depressions. Symptomatic and non-symptomatic plant samples were collected from the experimental farm of National Research Centre of Orchids, Pakyong Sikkim ...

The tospoviruses Tomato chlorotic spot virus (TCSV) and Groundnut ringspot virus (GRSV) cause high economic losses in several vegetable crops in Brazil. The glycoprotein precursor coding sequence was still not available for these two viruses. In this study, the 3' 4 kb M RNA of TCSV and GRSV genome was cloned and sequenced.

Groundnut ringspot virus is a negative-sense single-stranded RNA virus that belongs to the genus Tospovirus and is the prevalent member of this genus in Brazil. This work presents the nucleotide sequence of the L RNA, with a single open reading frame of 2873 amino acids in the complementary strand corresponding to the RNA-dependent RNA polymerase (L ...

First Report of Groundnut ringspot virus Infecting Tomato in South Florida
Plant Health Progress, 2010To the best of our knowledge this is the first report of GRSV in the United States in any host, although TSWV has been present in Florida for many years. Although the detection of GRSV in Florida tomatoes is cause for concern, the close relationship of GRSV and TSWV may allow successful adaptation of the integrated disease management strategies ...

Abstract Tomato crops are affected by various viral diseases. In Brazil, the most frequent of these diseases are caused by the begomovirus tomato severe rugose virus (ToSRV), the crinivirus tomato chlorosis virus (ToCV) and orthotospoviruses, mainly groundnut ringspot virus (GRSV) and tomato chlorotic spot virus ...

Citrullus lanatus is a New Natural Host of Groundnut ringspot virus in Brazil
Journal of Phytopathology, 2014AbstractIn 2012 and 2013, watermelon (Citrullus lanatus) plants from commercial crops in São Paulo State were found showing mosaic, necrotic lesions, leaf deformation and necrotic spots on the fruits, suggestive of tospovirus infection. Leaf and fruit samples were separately tested by PTA‐ELISA and reverse transcription polymerase chain reaction (RT ...

Groundnut ringspot virus: an Emerging Tospovirus Inducing Disease in Peanut Crops
Journal of Phytopathology, 2007AbstractPeanut (Arachis hypogaea L.) plants showing Tospovirus‐like symptoms were observed in Córdoba province (central Argentina). Peanut plants were collected and tested to identify the causal agent. Tospovirus‐like particles were observed by electron microscopy and Groundnut ringspot virus (GRSV) was identified by double antibody sandwich‐enzyme ...

To the best of our knowledge, this is the first report of GRSV infecting tomatillo and eggplant, and it is the first report of GRSV infecting pepper in the United States. This first identification of GRSV-infected crop plants in commercial fields in Palm Beach and Manatee Counties demonstrates the continuing geographic spread of the virus into ...

Currently, diseases caused by tospovirus species are among the most limiting factors for lettuce (Lactuca sativa L.) production in Brazil, where losses can reach up to 100%. In cultivated lettuce germplasm, the highest levels of resistance to tospoviruses were identified in the accession ‘PI 342444’ (= cultivar ‘Tinto’).
