Abstract
- Tomato plants (Lycopersicon esculentum Mill.) showing leaf yellowing or reddening, proliferation of lateral shoots, hypertrophied calyces, and greening of petals were found in four tomato-growing areas of central Italy during surveys carried out in 1999–2000. The highest disease incidence was recorded in 1999 (78%) and 2000 (82%) near Ronciglione (Viterbo province). The phytoplasmas associated with the disease were detected and characterised using PCR and RFLP. They belonged to 16S rRNA groups I, III, V and XII (sensu Lee et al., 1998. Int. J. Syst. Bacteriol., 48, 1153). Forty-five percent of tomato plants were infected with group I (max. 52% near Frascati and Ronciglione), 31% with group XII (max. 39% near Ronciglione) and 24% with other groups (max. 33% near Tarquinia and 23% near Fondi). Seven percent of tomato plants were infected with both group I and group XII. This is the first report of a group-III and a group-V phytoplasma found in tomato.
