First Report of Peanut Stunt Cucumovirus Naturally Infecting Desmodium sp

Differential interactions among isolates of peanut stunt cucumovirus and its satellite RNA.

The interactions of seven isolates of peanut stunt cucumovirus (PSV) originating from North America, Europe and Africa, and two variants of PSV satellite RNA (sat RNA) were analysed. Electrophoretic and immunoblot analyses of the coat protein (CP) and Northern blot hybridization analyses of the viral RNAs showed that isolates PSV F352, 1339 and 1507 belonged to subgroup I, and isolates PSV W, S...

Evidence for the occurrence of two distinct subgroups of peanut stunt cucumovirus strains: molecular characterization of RNA3.

Strains of peanut stunt cucumovirus (PSV) were classified into two distinct subgroups, I and II, based on Western and Northern blot analyses using antisera and cloned cDNA probes to strains PSV-ER and PSV-W. These results were corroborated by nucleotide sequence analyses of full-length cDNA clones of RNA3 from representative strains of the two subgroups. Whereas the percentage nucleotide sequen...

First Report of sp. Parasites Infecting Dinoflagellates from Brazilian Coastal Waters Amoebophrya

Members of the parasitic dinoflagellate genus lethally infect other marine dinoflagellates, including red tide forming and toxin-producing species. The known geographical distribution of sp. parasites in costal waters of the northern hemisphere is more likely reflecting a lack of information from other areas rather than the actual picture. We investigated the presence of sp. parasites infecting...

Tomato bushy stunt virus (TBSV) infecting Lycopersicon esculentum.

Tomato bushy stunt virus (TBSV) was detected in tomato crop (Lycopersicon esculentum) in Egypt with characteristic mosaic leaf deformation, stunting, and bushy growth symptoms. TBSV infection was confirmed serologically by ELISA and calculated incidence was 25.5%. Basic physicochemical properties of a purified TBSV Egh isolate were identical to known properties of tombusviruses of isometric 30-...
