Divergent molecular and growth responses of young "Cabernet Sauvignon" (Vitis vinifera) plants to simple and mixed infections with Grapevine rupestris stem pitting-associated virus.

ABSTRACT: Grapevine rupestris stem pitting associated virus (GRSPaV) is one of the most widely distributed viruses; even so, little is known about its effect on Vitis vinifera. To provide new insights, the effects of single and mixed GRSPaV infections on the V. vinifera cultivar "Cabernet Sauvignon" were studied by evaluating growth parameters, such as measurements of the total plant length, the number and distance of internodes and the number of leaves per shoot. In addition, parameters relating to gas exchange, i.e., the stomatal conductance, net photosynthetic rate, internal CO₂ concentration and leaf transpiration, were also assessed. All the measurements were performed in one- and two-year-old plants with a single GRSPaV infection or mixed infections of GR
