Abstract

The aim of this work was to create an easy, fast and sensitive method for the simultaneous detection of the most frequent viruses known to infect pepper (Capsicum annuum L.) crops. A multiplex RT-PCR assay was developed that successfully achieved this aim. Using specifically designed primer pairs, the assay could simultaneously amplify the genomes of members of the two subgroups (I and II) of cucumber mosaic virus (CMV), two tobamoviruses, tobacco mosaic virus (TMV) and pepper mild mottle virus (PMMoV), potato virus Y (PVY), and tomato spotted wilt virus (TSWV) in a single assay. The multiplex RT-PCR assay was found to be a sensitive diagnostic tool for the detection of the viruses from the leaves and fruits of naturally infected pepper plants. This assay would provide prompt disease status information for pepper breeders.

Keywords: CMV; PVY; Pepper; TSWV; Tobamovirus; multiplex RT-PCR.
