Abstract Reverse genetics systems are critical tools in combating emerging viruses which enable a better understanding of the genetic mechanisms by which viruses cause disease. Traditional cloning approaches using bacteria are fraught with difficulties due to the bacterial toxicity of many viral sequences, resulting in unwanted mutations within the viral genome. Here, we describe a novel in vitro workflow that leverages gene synthesis and replication cycle reaction to produce a supercoiled infectious clone plasmid that is easy to distribute and manipulate. We developed two infectious clones as proof of concept: a low passage dengue virus serotype 2 isolate (PUO-218) and the USA-WA1/2020 strain of SARS-CoV-2, which replicated similarly to their respective parental viruses. Furthermore, we generated a medically relevant mutant of SARS-CoV-2, Spike D614G. Results indicate that our workflow is a viable method to generate and manipulate infectious clones for viruses that are notoriously difficult for traditional bacterial-based cloning methods.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
