First report of recombination analysis of betasatellite and aplhasatellite sequence isolated from an ornamental plant marigold in India: An in silico approach

Abstract

The aim of this study were to present and highlight the in silico recombination analysis approach for in depth study about the nature of the virus. To detect the possibility of recombination in betasatellite and alphasatellite, Recombination Detection Program (RDP) was utilized, which is based on a pair wise scanning approach. The betasatellite and alphasatellite genomes were isolated from an ornamental plant Marigold and is identified as a new recombinant species, sharing nucleotide identity with other isolates reported from China and Pakistan. One factor favoring the spread of viruses among these plants is that many dicotyledonous species in India are hosts of whiteflies of the B. tabaci complex, which are the known or likely vectors of all the viruses. The present study remarkably suggests that the exchange of DNA with other viruses would create a new disease complex posing a serious threat to agriculture crops and horticulture ornamental plants production.
