Plant Virology Group

The primary focus of this group is on plant viruses especially gemini viruses, which are the major constraint for agricultural productivity in tropical and sub-tropical regions of the world. Begomoviruses (genus Begomovirus) are economically the most important geminiviruses and are only transmitted by the whitefly Bemisia tabaci. The main focus of research is on diversity and molecular characterization of begomovirus DNA components (DNA A, nanovirus-like alphasatellite and betasatellite) infecting cotton, tomato, chilies, pepper, tobacco, lufa, okra, weeds and other alternate hosts; cloning of the partial dimers which could produce infection; multiple infection and recombination in geminiviruses.
