| Abstract:
The agent causing chlorotic spots in Kalanchoë blossfeldiana ‘Isabella’ was investigated. A virus isolated from this naturally infected kalanchoë was mechanically transmissible to several indicator plants. Observation of suspension preparations in the electron microscope revealed rhabdovirus-like particles. On the basis of symptoms on indicator plants, serology, electron microscopy, molecular characterisation and back inoculation to K. blossfeldiana 'Isabella', the causal agent was identified as an isolate of Sonchus yellow net virus (SYNV). This is the first report of an ornamental plant species naturally infected by SYNV. | |
