Abstract:

With the development of molecular biology technology,a number of nucleic acid isothermal amplification technologies have been developed gradually. Recombinase polymerase amplification(RPA),as a rapid and sensitive detection technique,has great advantages. At present,RPA has been applied in many fields on detections,such as genetically modified organism,a variety of pathogens and food safety. As an emerging technology,RPA is developing rapidly in plant virus detection. The RPA technique requires only a pair of primers and is finished in only 30 min at constant temperature(37-42oC),which has high sensitivity and specificity. As a result,the RPA technique is rapidly becoming a very effective tool for detection of plant viruses in under-equipped laboratories or in on-site facilities. In this review,the detection principle,primer design and application for RPA are introduced,and the recent research progress and existing problems of RPA in plant virus detection is reviewed,aiming to provide references for the application of RPA in te detection of plant detection.

Key words: recombinase polymerase amplification, plant virus, detection, application
