Begomoviruses being the largest genera of Geminiviridae cause significant economical losses in a wide variety of crops in several tropical and subtropical regions of India and a major threats to food security. Begomoviruses are transmitted by the whitefly (Bemisia tabaci) in a circulative persistent manner. Begomoviruses as of their small genomes (ssDNA) and limited coding capacities, rely heavily on host machineries for infection. They interact with a wide range of plant proteins and process them to support viral DNA replication, gene expression, movement, and to neutralize host defenses. Many of these interactions have antagonistic effect on the growth of crops, resulting in symptoms that include stunting, vein clearing, curling, leaf deformation and loss in fruit quality and production. The main research studies focused on Begomoviruses are: identification, molecular characterization, sequence analysis, DNA replication, infectivity, phylogeny, functions of viral proteins, virus-host interaction, transgenic resistance, promoter analysis and virus based gene silencing vectors. This review presents current status of begomovirus research in India and future areas that need to be explored.
