RT-PCR based detection of Pepper mild mottle virus from capsicum seeds and seed transmission assay.

ABSTRACT: Pepper mild mottle virus (PMMoV), a Tobamovirus from Virgaviridae family, is highly contagious and transmitted by seeds as well as soil in nature. PMMoV has become a greater threat to capsicum cultivation worldwide. To develop an indigenous, rapid, and sensitive protocol for routine detection of PMMoV from seeds, the sensitivity of DAS-ELISA and RT-PCR was compared in the present study. The infected seeds of California Wonder were included in the study. Through DAS-ELISA the virus was successfully detected from 20 mg of seeds. However, using RT-PCR, we were able to detect the virus even from one infected seed with reproducibility. In the present study, vertical seed transmission of the test virus was investigated by employing a grow-out test under greenhouse conditions as wel
