Cotton leaf curl Bangalore virus

Family   : Geminiviridae
Genus    : Begomovirus
Acronym  : CLCuBV

Introduction

Emergence of novel viruses due to the recombination of begomoviruses and multiple satellite DNA molecules leading to the production of diverse symptoms and increase in newer host adaptation. The abundant number of begomoviruses and the continued reports of new species with the high degree of genetic diversity within species suggests that, the begomoviruses are subjected to high mutation rate generating highly diverse populations in a short time. Cotton leaf curl Bangalore virus (CLCuBV) is one such recombinant monopartite begomovirus infecting cotton and bhendi.
