Abstract
In April 2007, a severe disease occurred in Sicily (Italy) in a glasshouse cultivation of tenweeks stock (Matthiola incana R. Br.; Brassicaceae) belonging to the cultivar White-Beach. Plants were stunted and rosetted, and the flowers were of small size and characterized by virescence symptoms. Phytoplasma presence and identity was detected by applying PCR/RFLP techniques and sequencing on 16S ribosomal gene. Phytoplasmas were identified as belonging to ribosomal subgroup 16SrII-A, never reported before in Italy and showed % of homology with ‘Candidatus Phytoplasma aurantifolia’. This is the first report of a phytoplasma diseases of tenweeks stock. Considering that this Brassicaceae ornamental species is widely grown in Italy, it could play an im-portant role in the epidemiology of these phytoplasmas, new for Italy, spreading.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
