First report of Cucumber mosaic virus on Canna indica in Iran

Cucumber mosaic virus (CMV) was detected in Canna indica by enzyme linked immonusorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR) using CMV-specific primers. The Canna indica samples were collected from commercial horticultural greenhouses showing mosaic symptoms in the Varamin region in Tehran province of Iran. The virus infection was also confirmed on the basis of the symptoms on herbaceous indicator plants. To our knowledge, this is the first report of the natural occurrence of CMV on Canna indica in Iran.
