Phytochemical characterisation and toxicity effect of (Hemls.) A. Gray leaf extract on fall army worm (JE Smith) larvae.

Objectives: To mitigate the losses due to fall armyworm (FAW) infestation in maize, chemical pesticides had been the first choice and widely used as an emergency response. However, it comes with attendant health effect. This necessitates the development of plant based effective and safer pesticides.

AC4 protein of tomato leaf curl Palampur virus is an RNA silencing suppressor and a pathogenicity determinant.

Plants deploy RNA silencing as a natural defence against invading viruses involving sequence-specific degradation of the viral RNAs. As a counter-defence strategy, viruses encode suppressor proteins that simultaneously target different steps of the silencing machinery. Tomato leaf curl Palampur virus (ToLCPalV) is a bipartite begomovirus in Geminiviridae family.
