Complete genome sequence of a new bipartite begomovirus associated with leaf curl disease of Capsicum annum

Abstract

The complete bipartite genome, consisting of DNA-A and DNA-B, of a novel begomovirus isolate associated with apical leaf curling and crinkled leaf disease of Chili (Capsicum annum) from New Delhi, India was cloned and sequenced. The sequence of DNA-A (2737 nt) and DNA-B (2692 nt) of the virus was submitted to NCBI, USA under the accessions MK069591 & MG597211, respectively. Sequence identity of the common region (CR) and presence of identical iterons (GAGTG) between the DNA-A and DNA-B clones indicate that they constitute a related pair. The virus corresponds to a novel species of tomato leaf curl virus and sequence analysis has ruled out the involvement of recombination events in its evolution. Therefore, we report the complete nucleotide sequence of a new bipartite begomovirus infecting Capsicum annum, a vegetable crop communally cultivated throughout India.
