Recently, a new geminivirus, tentatively named Grapevine geminivirus A (GGVA), was reported in grapevines (Al Rwahnih et al. 2017). In the present study, bark scrapings from an ‘Ayaneskeal’ grapevine with foliar ringspots were used for the extraction of small RNAs and sequencing in 2012. The analysis generated approximately 29,319,407 Illumina reads of 16 to 28 nt in length and more than 463,611 reads were mapped to the GGVA genome. BLAST analysis showed also the presence of Grapevine leafroll-associated virus-3, Grapevine berry inner necrosis virus, Grapevine yellow speckle viroid 1, Grapevine yellow speckle viroid 2, and Hop stunt viroid. The full GGVA genome was amplified using two overlapping primers designed based on the sequences of the assembled contig [(23-1F/2R (5′-TGTCGGCCATGTCAGGGTGTT-3′) and (5′-GGCATAGATGATACAATTGCA-3′)]. Sequencing showed that the GGVA genome of isolate LN_ANSJ (GenBank accession no. KX950822) was 2,905 nt in length, and was 98% identical with the previously reported GGVA isolate NP (KX570610). The genome of LN_ANSJ had the same six open reading frames (ORFs) as the NP isolate, and the same nonanucleotide stem-loop sequence “TAATATT↓AC” in the intergenic region. Furthermore, two primers, C1-1F/1R (5′-CAGTATCTTCTGAGGCACGA-3′/5′-GCTAACGACGCTTATGCTGA-3′) and V1-1F/1R (5′-AAGAGGAAATCTTTCGCACC-3′/5′-AATTGACTCGATTACGACCAG-3′), were designed based on the sequences of C1 and V1 genes to amplify a 703-bp and 568-bp fragment in the Rep and CP genes of GGVA, respectively. In a survey of 69 grapevines of 20 different grapevine cultivars collected from four different provinces (Liaoning, Shandong, Ningxia, and Sichuan) in China, PCR testing using the primers C1-1F/1R and V1-1F/1R showed that 55% (38/69) of the samples tested positive for GGVA, and the incidence was high in the common cultivars and rootstocks such as Summer Black (100%, 6/6), Ruby Seedless (100%, 6/6), Cabernet Franc (71.4%, 5/7), and Beta grapevines (42.9%, 6/14). GGVA was not found in the native Amur grapevine ‘Beibinghong’ (0/8). Some PCR products were cloned and sequenced and sequencing confirmed them to be virus-specific. In the tested grapevines, most samples did not exhibit any symptoms, except for three grapevines which had foliar ringspots. The results suggested that GGVA may be widely distributed in China and may not cause obvious symptoms in many grapevine cultivars. To the best of our knowledge, this is the first report of GGVA in China.Reference:Al Rwahnih, M., et al. 2017.
