Coronavirus infection can cause serious respiratory and digestive system diseases in hu-mans and animals.In recent years,the frequent outbreaks and newly outbreaks of coronavirus in-fection have threatened global public health and the development of livestock and poultry.Howev-er,the development of anti-coronavirus drugs and vaccines was restricted due to the insufficient understanding of the mechanisms of coronavirus pathogenesis and cross species transmission.Re-verse genetic manipulation technology is a powerful tool in virological research,which can be used for the study of pathogenesis mechanisms,replication mechanisms and function analysis of protein.It is also be used in the development of attenuated or gene labeled vaccines,and antiviral drugs.Due to the large genome and complex structure of the coronavirus,the reverse genetic manipulation technology of coronavirus has been lagging for a long time.With the continuous updating of molec-ular biology methods,various new construction strategies have emerged.This article focuses on the construction strategy of the reverse genetic operating system for coronavirus,as well as its applica-tion in virus transmission and pathogenic mechanisms,and development of vaccines,which will provide favorable tools for the prevention and control of the coronavirus infection.
