First Report of Grapevine red blotch virus, the Causal Agent of Grapevine Red Blotch Disease, in Vitis vinifera in North Carolina

The Development of a Quantitative Assay for the Detection of Grapevine Red Blotch-associated Virus in Vitis vinifera Identifies Significant Differences in Virus Distribution

BIOLOGY AND SPREAD OF GRAPEVINE RED BLOTCH-ASSOCIATED VIRUS Principal Investigator: Co-Principal Investigator: Collaborator:

Grapevine red blotch-associated virus (GRBaV) was isolated from table and wine grapes, as well as rootstocks, affected by red blotch, a recently recognized viral disease. Phylogenetic analyses revealed the clustering of GRBaV isolates two groups (clades) of genetic variants (Krenz et al., 2014, Al Rwahnih et al., 2015). Producing and using a full-length infectious clone of a representative isol...

Characterization of Four Famous Red Grapevine Cultivars

The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Aro...

Sugars and flowering in the grapevine (Vitis vinifera L.).

Sugars play an important role in grapevine flowering. This complex process from inflorescence initiation to fruit maturity takes two growing seasons. Currently, most of the available data concern the involvement of sugars as energy sources during the formation of reproductive structures from initiation of inflorescences during the summer of the first year, until flower opening during the follow...

Chloroplast genome diversity in Portuguese grapevine (Vitis vinifera L.) cultivars.

Grapevine chloroplast (cp) DNA diversity was analysed for the first time through amplification and digestion of fragments of the large single copy (LSC) region by polymerase chain reaction-restriction fragment length polymorphism methodology and also by amplification of three microsatellite loci, previously described as polymorphic in grapevine. Thirty-eight grapevine cultivars collected mainly...
