Geminiviridae, the second largest family in the taxonomy of plant viruses, cause devastating plant diseases all over the world. Such devastating effect of geminiviruses to both staple food and cash crops is particularly predominant in tropical and subtropical countries exhibiting diverse types of symptom in plants. Based on the characteristics of their genome, host range and mode of transmission, the family Geminiviridae has been classified into four genera, i.e. Mastrevirus, Curtovirus, Topocuvirus and Begomovirus. Begomoviruses of a specific geographical region shares more sequence homology amongst them, than with begomoviruses from different geographical region infecting the same host. These viruses show rapid genomic variation. This variation could be due to mutation, recombination or pseudo-recombination, which was very much common phenomenon in begomoviruses.
