Detection and characterization of a new betasatellite: variation in disease symptoms of tomato leaf curl Pakistan virus-India due to associated betasatellite

Detection and characterization of a new betasatellite: variation in disease symptoms of tomato... A begomovirus and its associated betasatellites were amplified and sequenced from tobacco plants affected with leaf curl disease. The begomovirus was identified as a new strain of tomato leaf curl Pakistan virus (ToLCPKV), which is referred to here as ToLCPKV-India.

Abstract

A begomovirus and its associated betasatellites were amplified and sequenced from tobacco plants affected with leaf curl disease. The begomovirus was identified as a new strain of tomato leaf curl Pakistan virus (ToLCPKV), which is referred to here as ToLCPKV-India. A previously known betasatellite (tomato leaf curl Patna betasatellite (ToLCPaB)) and a new betasatellite were also found in leaf-curl-affected samples. The use of infectious clones of ToLCPKV-IN plus ToLCPaB for agroinoculation led to typical leaf curl, while ToLCPKV-IN together with the new betasatellite resulted in curling and chlorosis of leaves. Based on these disease symptoms, we propose to name the new betasatellite tobacco leaf chlorosis betasatellite (TbLChB).
