Characterization of cucumber mosaic virus (CMV) subgroup IB infecting chilli in Tamil Nadu, India.

ABSTRACT: CMV (cucumber mosaic virus) is the most primitive virus infecting chilli (Capsicum annuum. L). The mosaic incidence with leaf filiformity, mosaic mottling and stunted growth was observed in major chilli growing regions of Tamil Nadu. CMV sap was inoculated on chilli, cowpea, bitter gourd, bottle gourd, ridge gourd, banana, cucumber, Nicotiana and Chenopodium plants. Host range studies revealed that CMV produced localized infection on Nicotiana and systemic symptoms on most of the test plants. The occurrence of CMV was confirmed through DAC-ELISA and RT-PCR analysis. Host plant samples tested with DAC-ELISA showed strong reaction with 1.7 optical density. For molecular characterization, total RNA isolated from infected plants used in RT-PCR with CMV specific prim
