“…The subgroup 3 tobamoviruses are further classified into Ribgrass mosaic virus (RMV), Turnip vein clearing virus (TVCV) and Youcai mosaic virus (YoMV) clusters, based on coat protein phylogeny and host range [ 12 ]. Although they were historically considered as Brassicaceae infecting viruses they have a wide host range, with RMV isolates alone infecting taxonomically diverse Rosid and Asterid groups [ 1 ], comprising Actinidiaceae, Balsaminaceae, Brassicaceae, Caryophyllaceae, Liliaceae, Plantaginaceae and Scrophulariaceae [ 4 , 12 ].…”

BackgroundThe genus Tobamovirus (Virgaviridae) comprises 33 accepted species with the recent addition of eight new viruses and is divided in to three subgroups based on the origin of assembly of the virion and host range. Within the subgroup 1 tobamoviruses the orchid-associated tobamovirus was hypothesized to be a chimeric derivative of recombinations between genome fragments from subgroup 3 and 1. Recombination events involving RdRp, movement and coat protein genes are recorded within subgroup 1 and 2. However natural recombinations have not previously been reported between subgroup 3 tobamoviruses.FindingsThe organization and phylogenetic analyses of the complete genome and the different ORFs placed the new isolate within the Ribgrass mosaic virus clade of subgroup 3 tobamoviruses. Recombination detection analyses indicated that the isolate was a chimeric genome with fragments of high similarity to Ribgrass mosaic virus (RMV) strains NZ-439 (HQ667978) and Actinidia-AC (GQ401365.1) infecting herbaceous Plantago sp. and woody Actinidia spp., respectively. The recombinant differed across the whole genome by 3-8 % from other published RMV genomes.ConclusionIn this investigation we report an intra-specific recombination between RMV strains NZ-439 (HQ667978) and Actinidia-AC (GQ401365.1), in the replicase component between viral-methyltransferase and viral-helicase regions, resulting in a novel RMV strain FSHS (JQ319720.1) that represents the first described natural recombinant within the RMV cluster of subgroup 3 tobamoviruses.Electronic supplementary materialThe online version of this article (doi:10.1186/s12985-016-0487-5) contains supplementary material, which is available to authorized users.

“…The first virus naturally infecting kiwifruit was reported in 2003 (Clover et al , 2003) and only three kiwifruit viruses had been reported by 2010 (Clover et al , 2003; Chavan et al , 2009; 2013). Recent studies have shown that at least 17 viruses have been detected in natural infections of kiwifruit, including cucumber necrosis virus (CNV), radish mosaic virus (RMV), cherry leaf roll virus (CLRV), cucumber mosaic virus (CMV), citrus leaf blotch virus (CLBV), potato virus X (PVX), pelargonium zonate spot virus (PZSV), tomato necrotic spot associated virus (TNSaV), tomato zonate spot virus (TZSV), turnip vein clearing virus (TVCV), Actinidia virus A (AcVA), Actinidia virus B (AcVB), Actinidia virus X (AVX), Actinidia virus 1 (AcV‐1), Actinidia seed‐borne latent virus (ASbLV) and Actinidia chlorotic ringspot‐associated emaravirus (AcCRaV) (Pearson et al , 2011; Blouin et al , 2012; 2013; 2018; Chavan et al , 2012; 2013; James and Phelan, 2016; Wang et al , 2016; Zheng et al , 2017; Veerakone et al , 2018; Zhao et al , 2019).…”

Occurrence and molecular characterization of Actinidia virus C (AcVC), a novel vitivirus infecting kiwifruit (Actinidia spp.) in China

Kiwifruit (Actinidia spp.) is an economically important fruit crop in the world. China is the largest producer of kiwifruit in terms of both acreage and yield. In this study, a novel virus, tentatively named Actinidia virus C (AcVC), was discovered in Actinidia deliciosa ‘Xuxiang’ grown in commercial kiwifruit fields in the Shaanxi province, a major kiwifruit‐growing region in China. Sequencing of the complete genome showed that AcVC has 7,668 nucleotides (not including the poly‐(A) sequence). Complete genome comparison and phylogenetic analysis showed that AcVC is most closely related to AcVA and then to AcVB. AcVC shares 69.2% nucleotide identity with AcVA (GenBank accession number ). Based on these data, Actinidia virus C is assigned as a new tentative member of the genus Vitivirus in the family Betaflexiviridae. AcVC was found to infect A. deliciosa and A. chinesis, the two major cultivated kiwifruits. Infection frequency of AcVC varied with the kiwifruit‐growing regions and cultivars in the Shaanxi province of China.
