| Popis: | Stolbur phytoplasma infection has been reported, for the first time, in a new host, Solanum malacoxylon, growing in the Botanical Garden of Milan University. This shrub, native of South America, synthesizes vitamin D compounds, important for biomedical and biotechnological purposes. Pathogen detection was performed by light and transmission electron microscopy, and confirmed by molecular diagnosis, based on PCR and restriction fragment length polymorphic (RFLP) analysis of the phytoplasmal 16S rRNA and tuf genes. By means of enzymatic restriction and phylogenetic analysis on these genes, it was found that the phytoplasma belongs to the Stolbur group, taxonomic subgroup 16SrXII-A, thus indicating S. malacoxylon as an additional host for this pathogen. Solanum malacoxylon could be then involved in the natural Stolbur phytoplasma spreading throughout South American areas, where this wild plant grows endemically. |
