Grapevine rupestris stem pitting-associated virus (GRSPaV), a member of the genus Foveavirus within the family Flexiviridae, is the putative causal agent of the disease Rupestris stem pitting (RSP) of grapevines. GRSPaV comprises a family of variants whose pathological characteristics have not been determined. Recently, many of the indicator "St George" plants (Vitis rupestris) used throughout ...

In this study, we investigate the relation between explant size and success of virus elimination in ‘Superior Seedless’ grape variety. Plants were tested by prior to thermotherapy vitro culture using Double Antibody Sandwich-Enzyme-Linked Immunosorbent Assay (DAS-ELISA) Reverse Transcription-Polymerase Chain Reaction (RT-PCR) verified as infected different viruses (Grapevine leafroll associated...

Grapevine rupestris stem pitting-associated virus (GRSPaV) is a worldwide-distributed pathogen in grapevines with a high genetic variability. Our study revealed differences in the complexity of GRSPaV population in a single host. A single-variant GRSPaV infection was detected from the SK30 grapevine plant. On the contrary, SK704 grapevine was infected by three different GRSPaV variants. Variant...
