Field symptoms of chlorotic mottling and leaf deformations were observed on the cv Pinot gris (PG) in the Trentino region (Italy). Extensive assays excluded the presence of widely distributed nepo-, ampelo- and vitiviruses. An analysis of small RNA populations from two PG grapevines showing or not symptoms was carried out by Illumina high throughput(More)
Somatic mutation is a natural mechanism which allows plant growers to develop new cultivars. As a source of variation within a uniform genetic background, it also represents an ideal tool for studying the genetic make-up of important traits and for establishing gene functions. Layer-specific molecular characterization of the Pinot family of grape cultivars(More)
The role of Grapevine Pinot gris virus (GPGV) in the etiology of grapevine leaf mottling and deformation was investigated by biological and molecular assays. A survey on different cultivars from the Trentino Region in Italy showed a widespread distribution of GPGV, which was associated with symptomatic (79%) but also with symptomless (21%) vines.(More)
Grapevine Pinot gris Virus (GPGV) is a single stranded RNA of the genus Trichovirus infecting grapevine (Vitis vinifera) and associated with stunting, chlorotic mottling and leaf deformation symptoms. During a monitoring of GPGV infection in vineyards of the Trentino region in Italy, we have detected the virus in the herbaceous plants Silene latifolia(More)
