Genome complexity of begomovirus disease and a concern in agro-economic loss

Abstract

Significant agro-economic loss becomes a foremost concern in terms of productivity and feeding the expanding population. Among all plant pathogens, begomovirus is also one of the contagions which affect most monocot and dicots. Begomovirus is transmitted by the whitefly vector Bemisia tabaci and causes potential yield reduction in a number of economically important crops. The evolution of the new strain of begomovirus through genetic changes, climatic factors, and mutation drastically affects the agricultural yield and thus the economic loss. A strategic Begomo management would foster the healthier agricultural environment. The review focus on classification, genome organisation, replication, pathogenecity, phylogeny, genetic diversity, technology behind its suppression, concealment and kayo.
