In this study, we investigated the possible replication of orchid fleck virus (OFV), a segmented plant rhabdovirus, within its mite vector (<em>Brevipalpus californicus</em> s.l.) using quantitative RT-qPCR, western blotting and next-generation sequencing. Time-course RT-qPCR and western blot analyses showed an increasing OFV accumulation pattern in mites after virus acquisition. Since OFV genome expression requires the transcription of polyadenylated mRNAs, polyadenylated RNA fractions extracted from the viruliferous mite samples and OFV-infected plant leaves were used for RNA-seq analysis. In the mite and plant datasets, a large number of sequence reads were aligned to genomic regions of OFV RNA1 and RNA2 corresponding to transcribed viral gene mRNAs. This includes the short polyadenylated transcripts originating from the leader and trailer regions at the ends of the viral genome, which are believed to play a crucial role in viral transcription/replication. In contrast, a low number of reads were mapped to the non-transcribed regions (gene junctions). These results strongly suggested that OFV gene expression occurs both in mites and plants. Additionally, deep sequencing revealed the accumulation of OFV-derived small RNAs in mites, although their size profiles differ from those found in plants.

Among them, blackberry yellow vein-associated virus (BYVaV) is prevalent in blackberry-producing areas of the United States and, when present in the blackberry yellow vein disease complex with other viruses, can lead to substantial crop losses. To better understand BYVaV biology and its role in virus complex disease development, we developed a BYVaV-derived infectious clone and a virus-induced gene silencing (VIGS) vector. The infectious clone successfully induced systemic infection and symptom development in <em>Nicotiana benthamiana</em>. Additionally, transmission of the recombinant virus to indicator plants was confirmed using the whitefly vector <em>Trialeurodes vaporariorum</em>. The infectious clone was subsequently modified into a VIGS vector, with the foreign insert remaining stable for the length of the study. This work provides essential tools for advancing the study of BYVaV biology and conducting genomic studies in its natural hosts.</div></div>","PeriodicalId":23483,"journal":{"name":"Virus research","volume":"350 ","pages":"Article 199488"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11736398/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142569647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
