Abstract
Begomoviruses are the members of Geminiviridae, which mostly infects dicots. Vector which is the cause transmission of this virus are whiteflies Bemisiatabaci. They have been characterized into monopartite and bipartite genome associated with DNA A&B. including some devastating strains which are linked with monopartite genome. They infect a broad range of horticulture and vegetable crops resulting into a huge economic loss every year. It has been a nutshell for scientists since the twentieth century and till now there are regular updates in its strains. Total number of DNA-A sequences infecting in vegetables were 151. 30 Species including the extract from phylogenetic tree of maximum likelihood. Species from tree were 15 (Based on 91% identities Brown et al. 2015) Pair wise sequence comparison revealed 86% cutoff value and beyond this point new Species are predicted DNA -B consisted on total number of 17 sequences from which 13 Species were included ( Based on 69% sequence identities) Pair wise sequence Comparison for DNA-B segment depicted 69% Computational sequence analysis of DNA-A&B segments of Begomoviruses infecting vegetables.
