摘要： Apple stem grooving virus (ASGV) frequently occurs in apple (Malus) trees and shows high sequence variability. A sensitive detection is essential for effective forecast and control of this virus. The reverse transcription -duplex polymerase chain reaction (RT-dPCR) was developed after screening of primer combinations, adjustment of annealing temperature, and optimization of dosage of primer pair combination and cDNA. Then, RT-dPCR and RT-regular PCR (RT-rPCR) were used to detect ASGV in regenerated apple plants after thermotherapy and in nature growing apple trees. The results showed that the detection efficiency of RT-dPCR was the same as the total of two RT-rPCRs. Moreover, RT-dPCR was found a sensitive, rapid and simple method to detect ASGV from various apple plants. These findings might be useful in the prediction of viral disease in host plants and can also be helpful to construct the same detection assays for other viruses.
