Construction and biological activities of the first infectious cDNA clones of the genus Foveavirus.

Grapevine rupestris stem pitting-associated virus (GRSPaV, genus Foveavirus, family Betaflexiviridae) is one of the most prevalent viruses in grapevines and is associated with three distinct diseases: rupestris stem pitting, vein necrosis and Syrah decline. Little is known about the biology and pathological properties of GRSPaV. In this work, we engineered a full-length infectious cDNA clone for GRSPaV and a GFP-tagged variant, both under the transcriptional control of Cauliflower mosaic virus 35S promoter.
