Molecular characterization of a new begomovirus infecting Mirabilis jalapa in northern India

Molecular characterization of a new begomovirus infecting Mirabilis jalapa in northern India Begomoviruses are whitefly-transmitted single-stranded DNA viruses that are responsible for considerable economic losses.

The complete viral genome shared highest sequence identity of 87% with pedilanthus leaf curl virus (AM712436), reported from Pakistan.

Abstract

Begomoviruses are whitefly-transmitted single-stranded DNA viruses that are responsible for considerable economic losses. A begomovirus, alphasatellite and betasatellite were characterized in a Mirabilis jalapa plant exhibiting severe leaf curling and mottling symptoms. The complete viral genome shared highest sequence identity of 87% with pedilanthus leaf curl virus (AM712436), reported from Pakistan. Additionally, the viral genome was 84% identical to that of chilli leaf curl India virus (KX951415) and 83% identical to that of tobacco curly shoot virus (GU1999584), which were previously reported to infect M. jalapa in India and China, respectively. Based on the ICTV criterion for begomovirus species demarcation (≥91% sequence identity for the complete genome), the virus represents a new species, for which we propose the name Mirabilis leaf curl virus. The alphasatellite and betasatellite sequences were similar to the corresponding sequences of ageratum yellow vein India alphasatellite (KU852743; 99% identity) and tomato leaf curl Patna betasatellite (HQ180394; 86% identity) sequences, respectively. This report describes a new begomovirus-satellite disease complex in M. jalapa.
