Arabis mosaic virus on ornamental plants

Abstract

Arabis mosaic virus (ArMV) is pathogenic to a wide variety of plant species including ornamentals. Using the methods of test-plants, electron microscopy, and DAS-ELISA, ArMV was identified in ornamental plant species of the genera Arum L., Camassia Lindl., Crocus L., Dahlia Cav., Dicentra Bernh., Dieffenbachia sp., Eryngium L., Liatris Gaertn. Ex Schreb., Lychnis L., Muscari Mill., Iris L. and Phlox L., representing eight families. In naturally infected host plants, the virus was found in mixed infections with other viruses. Virus idenstity in five ornamental species was confirmed by RT-PCR. Keywords: Arabis mosaic virus, ornamental plants, identification, DAS-ELISA, RT-PCR
