Occurrence of Groundnut ringspot virus on Brazilian peanut crops

Journal of General Plant Pathology, 2014
A 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.

Natural mixed infections on Phalaenopsis species by groundnut bud necrosis orthotospovirus, cymbidium mosaic virus and odontoglossum ringspot virus in India

Indian Phytopathology, 2021
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 ...

First Report of Groundnut ringspot virus Infecting Tomato in South Florida

Plant Health Progress, 2010
To 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 ...

Characterization of the N Gene of a Groundnut Ringspot Virus (GRSV) Isolate from Argentina

Journal of Phytopathology, 1995
AbstractThis paper describes the characterization of a Tospotirus isolate (M316) from Mendoza, Argentina. The N gene was cloned and sequenced. The sequence obtained was compared with the N gene sequences of other tospoviruses. The percentages of the nucleotide homology and amino acid similarity showed that this isolate may be considered a member of the

Molecular characterization of the RNA-dependent RNA polymerase from groundnut ringspot virus (genus Tospovirus, family Bunyaviridae)

Archives of Virology, 2011
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 ...
