The rhabdovirus NC complexes, the minimal infectious units, are composed of the genomic RNA (gRNA) and the viral N protein, the P protein and the L protein. It infects more than a thousand species of plants and causes enormous economic losses (Pappu et al. 2019;223:2120–33. In the past decades, virus-plant-insect vector interactions have been extensively studied for plant positive-stranded RNA viruses and DNA viruses, which attributes to the availability of their powerful reverse genetics systems. 2019b). 2009;54:447–68.

Furthermore, although NSR viruses can replicate in insect vectors, appropriate insect cell lines are lacking for recovery of plant NSR viruses from their respective infectious clones (Hogenhout et al. Gao Q, Xu W-Y, Yan T, Fang X-D, Cao Q, Zhang Z-J, et al. Casein kinase 1 regulates cytorhabdovirus replication and transcription by phosphorylating a phosphoprotein serine-rich motif. The genetics of viruses are determined by mutations of their nucleic acid. Reverse genetics systems of plant NSR viruses will help to solve the fundamental questions of all aspects of viral cycles in the context of natural plant NSR virus infections.

Review Article. FUTURE APPLICATIONS OF REVERSE GENETICS SYSTEMS. Since lots of plants, especially monocot plants, are difficult to be transformed and regenerated, it remains a big challenge to directly infect seed embryo and get inheritable mutations in offspring plants. [Amplification of bacterial heat shock protein 60 gene using inverse PCR method]. The M segment encodes the precursor to two glycolproteins (Gn and Gc) in the negative sense and a nonstructural protein (NSm) in the positive sense. bioRxiv. The termini of VSV DI particle RNAs are sufficient to signal RNA encapsidation, replication, and budding to generate infectious particles. Infectious rabies viruses from cloned cDNA. Soil-borne wheat mosaic virus infectious clone and manipulation for gene-carrying capacity. Since RRV is an arthropod-borne virus that is transmitted by eriophyid mites naturally, conventional mechanical inoculation method for RRV transmission into plants is not effective (Pang et al. The L segment encodes the viral RNA-dependent RNA polymerase (RdRp) in the negative sense. PubMed Recently, Pang et al. NIH The matrix protein of a plant Rhabdovirus mediates superinfection exclusion by Inhibiting viral transcription. J Virol. 2011; Walker et al. Epub 2007 Dec 17. Therefore, rescue of infectious plant NSR viruses from cDNA clones strictly requires the core replication proteins together with their genome RNAs which can assemble into nucleocapsid (NC) complexes as minimal infectious units.

More than 90% of the plants regenerated from virus-infected tissues contained targeted and inheritable mutations (Ma et al. Google Scholar. Highly efficient DNA-free plant genome editing using virally delivered CRISPR–Cas9. 2019;164:1949–65. Reverse genetics systems of plant viruses allow gene manipulation on viral genomes, which greatly facilitates studies of viral pathogenesis and interactions with host organisms. Google Scholar.

This procedure of inverse PCR (IPCR) has many applications in molecular genetics, for example, the amplification and identification of sequences flanking transposable elements. In addition, these NSR-based vectors are promising tools for foreign protein expression and genome editing in plants or insects (Table 1). 2015). 2017). More recently, Ma et al. 2009; Hogenhout et al. Among the RRV seven monocistronic genomes, RNA1–4 encode the RdRp, G protein, nucleocapsid, and movement protein, respectively, and RNA1–4 are sufficient for RRV systemic infections. 2008; Kormelink et al.

We further confirmed that the P bodies traffic along the ER/actin network driven by myosin XI-K (Fang et al. 2007;25:3018–21. New York: Humana Press; 2016. p. 39–54.
