- During spring 2005, symptoms of a disease consisting of striking coalescent yellow spots, pale mosaic and slight deformations of the leaves were observed on the canopy of some plants of Passiflora edulis Sims. (family Passifloraceae, commonly known as purple passion fruit or granadilla, growing in a garden of the Naples area (southern Italy). The same plants showed pale coloration of the flowers whereas fruits were apparently normal. In summer, symptoms on the new vegetation became milder. Uranyl acetate stained leaf-dip preparations observed under the electron microscope showed isometric virus particles ca. 30 nm in diameter.
Symptoms observed in herbaceous hosts plants, after mechanical inoculation with sap from symptomatic P. edulis leaves, and transmission tests with Myzus persicae indicated that Cucumber mosaic virus (CMV) was the likely agent of the disease. Virus identity was confirmed by DAS-ELISA with commercial antisera against CMV, made with leaf sap extracts from P. edulis and artificially inoculated symptomatic hosts (Nicotiana glutinosa, Nicotiana benthamiana). CMV has previously been reported as the agent of passiflora mosaic disease, from several tropical and subtropical countries (i.e. Australia, Africa, New Guinea, New Zealand), where granadilla cultivations are of economic importance. In Italy, P. edulis is grown as ornamental plant, mostly for its attractive flowers. This is the first report of CMV from P. edulis in Italy. (literal)

- Abstract
- During spring 2005, symptoms of a disease consisting of striking
coalescent yellow spots, pale mosaic and slight deformations
of the leaves were observed on the canopy of some plants of Passiflora
edulis Sims. (family Passifloraceae, commonly known as \"purple passion fruit\" or \"granadilla\", growing in a garden of the
Naples area (southern Italy). The same plants showed pale coloration
of the flowers whereas fruits were apparently normal. In
summer, symptoms on the new vegetation became milder. Uranyl
acetate stained leaf-dip preparations observed under the electron
microscope showed isometric virus particles ca. 30 nm in diameter. (literal)
