Development of a multiplex RT-RPA assay for simultaneous detection of three viruses in cucurbits.

ABSTRACT: Begomoviruses and criniviruses, vectored by whiteflies (Bemisia tabaci), are important threats to crops worldwide. In recent years, the spread of cucurbit leaf crumple virus (CuLCrV), cucurbit yellow stunting disorder virus (CYSDV) and cucurbit chlorotic yellows virus (CCYV) on cucurbit crops has been reported to cause devastating crop losses in many regions of the world. In this study, a multiplex recombinase polymerase amplification (RPA) assay, an isothermal technique for rapid and simultaneous detection of DNA and RNA viruses CuLCrV, CYSDV and CCYV was developed. Highly specific and sensitive multiplex RPA primers for the coat protein region of these viruses were created and evaluated. The sensitivity of the multiplex RPA assay was examined using serially diluted plasmid containing the
