Induction of PR-protiens in Co 43 plants following antiviral principle application and inoculation with rice tungro virus

Abstract

The levels of PR-proteins following application of antiviral prinicples (AVPs) and inoculation with rice tungro virus (RTV) at 5, 10, 15, 20 and 25 days after inoculation were assessed by enzyme linked immunosorbent assay (ELISA) technique. Treatment of rice plants with pigeonpea-AVP (PAVP) and mungbean - AVP (MAVP) and inoculation with RTV increased the levels of PR-proteins (PR1a and PR2) to significant levels compared to healthy and RTV-inoculated control plants. The reduction in per cent infection of RTV and restriction of titres of RTD-associated viruses may be as a result of the induction of defense-related compounds induced by the AVPs.
