SARS-CoV-2, the causative agent of COVID-19, has been responsible for a million deaths worldwide as of September 2020. At the time of this writing, there are no available US FDA-approved therapeutics for the treatment of SARS-CoV-2 infection. Here, we describe a detailed protocol to generate recombinant (r)SARS-CoV-2 using reverse-genetics approaches based on the use of a bacterial artificial chromosome (BAC). This method will allow the production of mutant rSARS-CoV-2-which is necessary for understanding the function of viral proteins, viral pathogenesis and/or transmission, and interactions at the virus-host interface-and attenuated SARS-CoV-2 to facilitate the discovery of effective countermeasures to control the ongoing SARS-CoV-2 pandemic. © 2020 Wiley Periodicals LLC.
