Shvets D, Sandomirsky K, Porotikova E, Vinogradova S. Metagenomic Analysis of Ampelographic Collections of Dagestan Revealed the Presence of Two Novel Grapevine Viruses. Viruses 2022; 14:v14122623. [PMID: 36560627 PMCID: PMC9781968 DOI: 10.3390/v14122623] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 11/21/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022] Open
Abstract
In this study, we analyzed the virome of 73 grape samples from two Dagestan ampelographic collections in Russia using high-throughput sequencing of total RNAs. Fourteen viruses and four viroids were identified, with one to eleven of them detected in each plant. For the first time in Russia, we identified grapevine leafroll-associated virus 7 and grapevine Kizil Sapak virus. A total of 206 genomes of viruses and viroids were obtained, and their phylogenetic analysis was carried out. The de novo assembly and tblastx analysis allowed us to obtain contigs of a novel (+) ssRNA genome of a plant virus from the genus Umbravirus, which was tentatively named grapevine umbra-like virus (GULV), as well as contigs of a novel dsDNA pararetrovirus from the genus Caulimovirus, which was tentatively named grapevine pararetrovirus (GPRV). Complete genomes of these viruses were obtained and used for Sequence Demarcation Tool (SDT) analysis and phylogeny studies. GULV and GPRV were detected in 16 and 33 germplasm samples from the Dagestan collections, respectively.

Abstract
Viruses and viroids prevalent in a population of 42 wild grapevines (i.e., free-living, uncultivated grapevines; Vitis spp.) were compared with those in a population of 85 cultivated grapevines collected in Tennessee, United States by RNA sequencing analysis of pools of ribosomal RNA-depleted total RNA. The sequences of 10 viruses (grapevine fleck virus, grapevine leafroll-associated virus 2, grapevine rupestris stem pitting-associated virus, grapevine Syrah virus 1, grapevine vein-clearing virus, grapevine virus B, grapevine virus E, tobacco ringspot virus, tomato ringspot virus, and a novel nano-like virus) and two viroids (hop stunt viroid and grapevine yellow speckle viroid 1) were detected in both grapevine populations. Sequences of four viruses (grapevine associated tymo-like virus, grapevine leafroll-associated virus 3, grapevine red blotch virus, and grapevine virus H) were identified only from cultivated grapevines. High, moderate, and low numbers of sequence reads were identified only from wild grapevines for a novel caulimovirus, an enamovirus, and alfalfa mosaic virus, respectively. The presence of most virus sequences and both viroids was verified independently in the original samples by reverse-transcription PCR followed by Sanger sequencing. Comparison of viral sequences shared by both populations showed that cultivated and wild grapevines harbored distinct sequence variants, which suggests that there was limited virus movement between the two populations. Collectively, this study represents the first unbiased survey of viruses and viroids in both cultivated and wild grapevines within a defined geographic region.

Abstract
Grapevine vein clearing virus (GVCV) causes severe stunting and death of cultivated grapevines and is prevalent in native Vitis spp. and Ampelopsis cordata in the Midwest region of the United States. GVCV can be transmitted from wild A. cordata to Vitis spp. by grape aphid (Aphis illinoisensis) under greenhouse conditions, but its prevalence, genetic composition, and genome number in native grape aphids are unknown. In this study, we collected grape aphids from native Vitaceae across the state of Missouri in 2018 and 2019, and conducted diagnostic, genetic, and quantitative analyses. GVCV was detected in 91 of the 105 randomly sampled communities on 71 Vitaceae plants (87%). It was present in 211 of 525 single grape aphids (40%). Diverse GVCV variants from aphids were present on both GVCV-negative and GVCV-positive plants. Identical GVCV variants were found in grape aphids sampled from wild and cultivated Vitaceae, indicating that viruliferous aphids likely migrate and disperse GVCV variants among wild and cultivated Vitaceae. In addition, we found that the number of GVCV genomes varies largely in the stylet and body of individual aphids. Our study provides a snapshot of GVCV epidemics and genetic structure in its mobile vector and sessile hosts. This presents a good model for studying the epidemiology, ecology, and evolution of a plant virus.

Abstract
Grapevines (Vitis spp.) host viruses belonging to 17 families. Virus-associated diseases are a constant challenge to grape production. Genetic resources for breeding virus-resistant grape cultivars are scarce. 'Norton' is a hybrid grape of North American Vitis aestivalis and is resistant to powdery mildew and downy mildew. In this study, we assessed resistance of 'Norton' to grapevine vein clearing virus (GVCV), which is prevalent in native, wild Vitaceae and in vineyards in the Midwest region of the U.S. We did not detect GVCV in 'Norton' as either the scion or the rootstock up to 3 years after it was grafted with a GVCV-infected 'Chardonel' grapevine. Upon sequencing of small RNAs, we were able to assemble the GVCV genome from virus small RNAs in GVCV-infected 'Chardonel' scion or rootstock, but not from grafted 'Norton' scion and rootstock. This study unveils a new trait of 'Norton' that can be used in breeding GVCV-resistant grape cultivars, and to investigate genetic mechanisms of 'Norton' resistance to GVCV.

Abstract
Grapevine vein clearing virus (GVCV) is associated with a vein-clearing and vine-decline disease. In this study, we surveyed wild Ampelopsis cordata from the Vitaceae family and found that 31% (35 of 113) of native A. cordata plants are infected with GVCV. The full-length genome sequence of one GVCV isolate from A. cordata shared 99.8% identical nucleotides with an isolate from a nearby cultivated 'Chardonel' grapevine, suggesting the occurrence of an insect vector. To identify a vector, we collected Aphis illinoisensis (common name: grape aphids) from wild A. cordata plants and detected GVCV in the aphid populations. We found that A. illinoisensis is capable of transmitting GVCV from infected A. cordata to Chardonel grapevines in the greenhouse. Upon transmission, GVCV caused severe symptoms on the infected Chardonel 45 days post transmission. We conclude that wild GVCV isolates from A. cordata are capable of inducing a severe disease on cultivated grapevines once they spread from native A. cordata to vineyards via grape aphids. The discovery of a natural reservoir and an insect vector of GVCV provides timely knowledge for disease management in vineyards and critical clues on viral evolution and epidemiology.

Abstract
The distribution and diversity of grapevine red blotch virus (GRBV) and wild Vitis virus 1 (WVV1) (genus Grablovirus; family Geminiviridae) were determined in free-living Vitis spp. in northern California and New York from 2013 to 2017. Grabloviruses were detected by polymerase chain reaction in 28% (57 of 203) of samples from California but in none of the 163 samples from New York. The incidence of GRBV in free-living vines was significantly higher in samples from California counties with high compared with low grape production (χ2 = 83.09; P < 0.001), and in samples near (<5 km) to compared with far (>5 km) from vineyards (χ2 = 57.58; P < 0.001). These results suggested a directional spread of GRBV inoculum predominantly from vineyards to free-living Vitis spp. WVV1 incidence was also significantly higher in areas with higher grape production acreage (χ2 = 16.02; P < 0.001). However, in contrast to GRBV, no differential distribution of WVV1 incidence was observed with regard to distance from vineyards (χ2 = 0.88; P = 0.3513). Two distinct phylogenetic clades were identified for both GRBV and WVV1 isolates from free-living Vitis spp., although the nucleotide sequence variability of the genomic diversity fragment was higher for WWV1 (94.3 to 99.8% sequence identity within clade 1 isolates and 90.1 to 100% within clade 2 isolates) than GRBV (98.3% between clade 1 isolates and 96.9 to 100% within clade 2 isolates). Additionally, evidence for intraspecific recombination events was found in WVV1 isolates and confirmed in GRBV isolates. The prevalence of grabloviruses in California free-living vines highlights the need for vigilance regarding potential grablovirus inoculum sources in order to protect new vineyard plantings and foundation stock vineyards in California.

Viral small RNAs reveal the genomic variations of three grapevine vein clearing virus quasispecies populations. Virus Res 2017; 229:24-27. [PMID: 28012998 DOI: 10.1016/j.virusres.2016.12.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Revised: 12/19/2016] [Accepted: 12/20/2016] [Indexed: 11/23/2022]
Abstract
Viral small RNAs (vsRNAs) include viral small interfering RNAs (vsiRNAs) that are initiators and products of RNA silencing, and small RNAs that are derived from viral RNAs with function still unknown. Sequencing of vsRNAs allows assembling of viral genomes and revelation of viral population variations at genomic levels. Grapevine vein clearing virus (GVCV) is a new member of the family Caulimoviridae whose DNA genome is replicated by reverse transcription of pre-genomic RNA molecules. In this short report, three genomic sequences of GVCV were assembled from vsRNAs that were isolated and sequenced from three individual grapevines in commercial vineyards and compared to the GVCV-CHA reference genome. Profiles of single nucleotide polymorphism among three viral populations indicated a closer relatedness between two populations in different grape cultivars at the same location than those in the same grape cultivar at different locations, suggesting the spread of GVCV populations among vineyards of close proximity. Classic types of vsiRNAs (21-nt, 22-nt, and 24-nt) were found in the three GVCV vsiRNA populations, but these did not produce alignment hotspots on the GVCV-CHA reference genome. The number of 36-nt reads is the highest among vsRNAs, the role of these vsRNAs remains unclear. The analysis of vsRNAs provides a first holistic picture of genomic variations among GVCV viral quasispecies populations that help monitor epidemics and evolution of GVCV populations, an emerging virus that is becoming a threat to grape production in the Midwest region of the USA.
