Co-evolution between Grapevine rupestris stem pitting-associated virus and Vitis vinifera L. induces a decrease in defence responses and physiological performance associated with an increase in photosynthesis-related gene transcription

ABSTRACT: Grapevine rupestris stem pitting-associated virus (GRSPaV) is a widespread virus affecting Vitis spp. Although it has established a compatible viral interaction in Vitis vinifera L. without the development of phenotypic alterations, it can occur as distinct variants that show different symptoms in diverse Vitis species. We investigated the changes induced by GRSPaV in V. vinifera cv Bosco, an Italian white grape variety, by combining agronomic, physiological, and molecular approaches, in order to provide comprehensive information about the global effects of GRSPaV. In two consecutive years, this virus caused a moderate decrease in physiological efficiency, yield performance, and sugar content in berries associated with several transcriptomic alterations. Transcript profiles were analysed b
