“…Infected leaves of Vitis vinifera vines exhibit star-shaped chlorotic spots [20]. The distribution of GAMaV is limited not only in Canada and USA, where it was first discovered [97,99,100], but also in Japan [101], Uruguay [102], France [103], Italy [104], and Spain [105]. To our knowledge, GAMaV has not been detected in the world's grapevine collections.…”

Grapevine germplasm collections are unique repositories of grape cultivars; therefore, it is necessary to minimize their infection with pathogens, including viruses, and develop various programs to maintain them in a virus-free state. In our study, we examined the virome of the largest Russian grapevine germplasm collection, the Anapa Ampelographic Collection, using high-throughput sequencing of total RNAs. As a result of bioinformatics analysis and validation of its results by reverse transcription PCR (RT-PCR) and quantitative RT-PCR (RT-qPCR), we identified 20 viruses and 3 viroids in 47 libraries. All samples were infected with 2 to 12 viruses and viroids, including those that cause economically significant diseases: leafroll, fleck, and rugose wood complex. For the first time in Russia, we detected Grapevine virus B (GVB), Grapevine virus F (GVF), Grapevine asteroid mosaic-associated virus (GAMaV), Grapevine Red Globe virus (GRGV), Grapevine satellite virus (GV-Sat), Grapevine virga-like virus (GVLV), Grapevine-associated jivivirus 1 (GaJV-1) and Vitis cryptic virus (VCV). A new putative representative of the genus Umbravirus with the provisional name Grapevine umbra-like virus (GULV) was also identified in Russian grape samples.

“…Limited occurrence of three more viruses (GRGV, GSyV-1, and GAMaV) was observed. An interesting observation is that GAMaV, a marafivirus, that has been reported in California [ 32 ], Canada [ 57 ], Japan [ 53 ], Uruguay [ 58 ], France [ 59 ], Spain [ 60 ], Italy [ 61 ], Russia [ 3 ], and Hungary [ 5 ], is reported for the first time in the Czech Republic in this study, although it was found in only one plant (KA7). Expanding its genome sequence would be of great interest, especially since its detection in the Czech Republic came from an asymptomatic grapevine.…”

This study focused on the viruses of the Tymoviridae family that infect grapevines in the Czech Republic. Complete sequences of GFkV (grapevine fleck virus) and GRGV (grapevine red globe virus) from the genus Maculavirus and GRVFV (grapevine rupestris vein feathering virus) and GSyV-1 (grapevine Syrah virus 1) from the genus Marafivirus were obtained using high-throughput sequencing of small RNAs and total RNAs. Mixed infections with these viruses were observed, as well as several variants of these viruses in the same plant. Phylogenetic analysis showed the position of the newly obtained virus isolates within the Tymoviridae family. Recombinant analysis provided evidence of single and multiple intraspecific recombinations in GRGV, GSyV-1, and GRVFV. Additionally, GAMaV, a grapevine virus from the genus Marafivirus, was reported for the first time in the Czech Republic.
