This is a preview of subscription content, Alma A, Davis RE, Vibio M et al (1996) Mixed infection of grapevines in northern Italy by phytoplasmas including 16S rRNA RFLP subgroup 16SrI-B strains previously unreported in this host. Spiroplasma citri was identified in 1971 as a causative agent of citrus stubborn disease. Phytoplasma disease in plants are generally seen as “yellows,” a form of disease common in many plant species. These keywords were added by machine and not by the authors.

In particular, it has been determined that, among the plant species infected by phytoplasmas, grapevine is one of those that are most severely affected, at a worldwide level. Phytoplasmas were first described in 1967 as the probable cause of plant yellow diseases. They were discovered by scientists in 1967 and were named mycoplasma -like organisms or MLOs. Phytoplasmas interact with their hosts in a strong manner, through manipulation of the morphological features of the plants, and in several cases, also of the biology of their insect vectors.

(Volume 5). Molecular genetics analyses have improved the understanding of phytoplasma taxonomy, and also enhanced the ability to identify phytoplasmas that are detected in hosts and insect vectors. Aust J Grape Wine Res 1:25–31, Quaglino F, Zhao Y, Casati P et al (2013) ‘, Safarova D, Zemanek T, Valova P, Navratil M (2016) ‘. Together with the new possibility to cultivate phytoplasmas in artificial media, molecular genetics studies are now opening possibilities for studying the best management of these bacteria that severely threaten worldwide agriculture, and in particular viticulture.

The collective RFLP patterns of amplified 16S rDNA differed from the patterns described previously for other phytoplasmas.
