Abstract: Infectious cDNA clones are an important tool to study the molecular and cellular process of RNA virus infection. In vitro and in vivo transcription systems are the two main strategies used in the generation of infectious cDNA clones for RNA viruses. This study describes the first generation of a full-length infectious cDNA clone of Cowpea mild mottle virus (CPMMV), a Carlavirus. The full-length genome was synthesized by Overlap Extension PCR of two overlapping fragments and cloned in a pUC-based vector under control of the SP6 RNA polymerase promoter. After in vitro run-off transcription, the produced RNA was mechanically inoculated into soybean plants cv. CD206. The systemic infection was confirmed by RT-PCR and further sequencing of amplified cDNA fragments. To simplify the transfection process, the complete genome was subcloned into a binary vector under control of the 35S promoter of cauliflower mosaic virus by the Gibson Assembly protocol. The resulting clones were inoculated by particle bombardment onto soybean seedlings and the recovery of the virus was confirmed 2 weeks later by RT-PCR. Our results indicate the constructs of the full-length cDNA of CPMMV are fully infectious in both in vitro and in vivo transcription strategies.
