Phytoplasmas are microorganisms associated with a number of severe plant diseases affecting many areas of diverse agricultural cultivations worldwide. The discovery of a new group of plant pathogens related to bacteria led to the finding of polymorphic, wall-less prokaryotes, located in the phloem of many plant species affected by yellows-type diseases believed to be caused by viruses, considering their infectious nature, and transmission by insects. Molecular data have provided considerable insights into their molecular diversity and genetic interrelationships and significant taxonomic progress has been achieved by the study of the 16S ribosomal gene with full sequencing of four strains. However there is a gap between taxonomy and diseases since it is not uncommon that the same disease is associated with molecularly differentiable phytoplasmas and this is quite common with diseases described in different areas of the world (Lee et al., 1998). During the last ten years, the use of molecular methods has enabled the detection and characterization of phytoplasmas associated with major fruit tree and grapevine diseases in Europe

Abstract
Phytoplasmas are microorganisms associated with a number of severe plant diseases affecting many areas of diverse agricultural cultivations worldwide. The discovery of a new group of plant pathogens related to bacteria led to the finding of polymorphic, wall-less prokaryotes, located in the phloem of many plant species affected by yellows-type diseases believed to be caused by viruses, considering their infectious nature, and transmission by insects. Molecular data have provided considerable insights into their molecular diversity and genetic interrelationships and significant taxonomic progress has been achieved by the study of the 16S ribosomal gene with full sequencing of four strains. However there is a gap between taxonomy and diseases since it is not uncommon that the same disease is associated with molecularly differentiable phytoplasmas and this is quite common with diseases described in different areas of the world (Lee et al., 1998). During the last ten years, the use of molecular methods has enabled the detection and characterization of phytoplasmas associated with major fruit tree and grapevine diseases in EuropeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
