“…Our study aimed to update the phylogeny of the world population of GPGV, both in space and time and to place the German population of the virus in that world context. In 2020 similar studies of GPGV populations by Hily et al (2020) and Tokhmechi et al (2021) concluded that GPGV emerged in China in the mid-20th century and spread to Europe, initially Italy, and from there, it spread to the rest of the world, and even back to China. Recently, more GPGV sequences have been stored in GenBank, and particularly significant for phylogenetic dating are those from two isolates of GPGV from Japan found in V. coignetiae, a wild grapevine of North-east Asia (Abe & Nabeshima, 2021), that we found to be basal in the GPGV phylogeny.…”

“…We have shown that German GPGV isolates were found in four clusters (B, C, D and E). The German isolates were genetically more diverse, for both genes, than those of other European populations, suggesting that the initial stages of GPGV's invasion of Europe were in Germany, not Italy (Hily et al., 2020; Tokhmechi et al., 2021). In contrast, most GPGV isolates from other regions (Australia, United States, France, Russia, Japan and China) tended to cluster according to their origin, as previously described (Elçi et al., 2018; Fajardo et al., 2017; Hily et al., 2020; Tokhmechi et al., 2021).…”

Grapevine Pinot gris virus (GPGV) isolates were obtained from German vineyards to investigate their diversity. Phylogenetic and dating analyses of these and GPGV genes and genomes available in GenBank showed that the virus probably diverged from grapevine berry inner necrosis virus (GINV) in wild and cultivated Vitis species, notably Vitis coignetiae, growing in North‐east Asia around 3500 years ago. GPGV probably infected the Eurasian grape (Vitis vinifera subsp. vinifera) when those cultivars were first taken to China during the Han Dynasty (226 BCE–220 CE). GPGV then spread to Europe around 1800 CE, probably via the dissemination of infected plants, and from there, eventually spread worldwide. German isolates were only found in all parts of the post‐1800 CE phylogeny. The German isolates were genetically more diverse, for both MP and CP genes, than those of other European populations, suggesting that the initial stages of the GPGV invasion of Europe were in Germany, not Italy. We discuss the likely North‐east Asian origin of both GPGV and GINV, and the possible coincidences of phylogenetic date estimates with changes to European and world viticulture practices.

The conundrum of the connection of grapevine Pinot gris virus with the grapevine leaf mottling and deformation syndrome

et al. 2022

Since its discovery in 2012, the role of the trichovirus named grapevine Pinot gris virus (GPGV) as the causative agent of grapevine leaf mottling and deformation (GMLD) syndrome, a grapevine disease for which symptoms had been observed in north Italy and western Slovenia a few years earlier, has been a matter of discussion. In the following 10 years of investigations, evidence has emerged of a role for the genetic diversity of the virus and for the varietal diversity of the host, as well as their interaction during antiviral defence (i.e. RNA silencing) and virus‐mediated defence suppression. In a context of wider research efforts, several relevant aspects of GPGV evolution and GMLD epidemiology were also clarified. Nevertheless, a complete understanding of the molecular events and the environmental conditions that could affect viral infection severity and symptom display remains a challenging puzzle. In the meantime, we are witnessing a large spread of the virus, which has almost completely permeated the regions where it first appeared, while spreading through most areas of grapevine cultivation. A deeper knowledge of the molecular context of the disease is key to establishing whether the impressive potential of GPGV to spread makes it a candidate as the next emerging threat for the grapevine industry.

“…Recombination and reassortment are the most frequently found evolutionary forces in populations of both RNA and DNA plant viruses, thus significantly affecting their genetic variation (Chare and Holmes, 2006;Gibbs et al, 2008). While population genetics of many emerging plant RNA viruses have been discussed in recent papers (Randa-Zelyüt and Ertunç, 2021;Tokhmechi et al, 2021;Morca et al, 2022), the genetic variability and evolutionary mechanisms of populations of DNA viruses were remained less studied (Sanz et al, 1999;Ng et al, 2011). Citrus spp., themselves, as commercially important fruits in Turkey, are constantly improved through breeding (Kurtuluş et al, 2021).…”

Citrus spp. is widely planted in tropical and subtropical regions, including in Turkey and other Mediterranean countries. Due to its widespread vector and climate change, Citrus chlorotic dwarf-associated virus (CCDaV), a member of the newly formed genus Citlodavirus, is one of the emerging viruses that can be a serious constraint to Citrus crops production in the coming years. Therefore, in-silico analysis on all available isolates in NCBI GenBank was performed to provide the first insight into the genetic population and evolution of CCDaV, which may contribute to its control. CCDaV phylogroups based on full genome, complete movement protein, and complete coat protein sequences were found to be not associated with isolate origins or host species, and all isolates also shared a high genetic identity among them. However, neutrality tests indicated that the current populations are expanding, driven by new mutations. Low Fixation index (FST) values (0.00000-0.36207) confirmed no genetic separation among different ORFs of isolates from three countries. The constructed TimeTree suggested that CCDaV emergence was very recent compared to the other three members of the genus Citlodavirus. Therefore, the obtained results of this study could also expand our knowledge on other even more obscure citladovirus and even other plant DNA viruses, which are still less studied than RNA viruses.
