Update on the origin of grapevine Pinot gris virus and its molecular characterization in Germany

Original language description

Grapevine Pinot gris virus (GPGV) is a member of the Trichovirus genus, with a positive single stranded RNA genome. The virus was discovered in symptomatic grapevines in northern Italy in 2012. Following that, the virus was reported from numerous grapevine-growing regions in many countries around the world. In order to molecularly characterize the GPGV isolates in Germany, the MP/CP region (1517nt) of 56 isolates was used for this purpose together with 187 NCBI-retrieved GPGV sequences. A time tree was generated to update the probable origin and dispersal of the virus. The ML-phylogenetic tree based on the MP/CP sequences showed that the German isolates clustered with those mainly from Europe, but also with some of worldwide origin. The German population had a high haplotype diversity for both MP and CP. The variability within the German GPGV population is particularly high. The molecular dating indicates that the basal isolates are those from Japan, probably representing the ancestral population of Chinese isolates.
