Development of PCR-base Diagnostic System for the Detection of Andean potato latent virus

Abstract

: Andean potato latent virus (APLV) is a phytopathogenic virus that belongs to the Group IV (+) sense ssRNA viruses of the genus Tymovirus. It mainly infects potatoes and is specified as a controlled quarantine virus in Korea. In this study, two primer sets of RT-PCR and nested PCR [set 2 (404 → 259 bp) and set 23 (501 → 349 bp)], were selected, which can rapidly and accurately diagnose APLV in quarantine sites. In addition, a modified-positive control plasmid is development, can possible verification of laboratory contamination in diagnosis of APLV detection. The PCR-base system developed in this study is expected to diagnose APLV and contribute to the plant quarantine in Korea.
