Characterization of a Cucumber mosaic virus isolate infecting Mandevilla sanderi (Hemsl.) Woodson

2005

In 2004, virus-like symptoms consisting of yellow rings in older leaves were observed in the foliage of Mandevilla sanderi grown from shoots in the province of Catania (Sicily, Italy). The plants were tested for virus presence using DAS-ELISA, mechanical inoculations to the host, RT-PCR and SSCP. Serological tests detected Cucumber mosaic virus (CMV) in all symptomatic leaf samples. The virus was mechanically transmitted to 11 of the 15 host species tested, including some of the Chenopodiaceae and Solanaceae families; indicator plants showed symptoms typical of CMV subgroup I. RT-PCR, SSCP and cloning were employed to characterize this CMV isolate, and to make clear its genetic relationship…
