Resumen:
Up to now phytoplasmas enclosed in four ribosomal groups (16SrI, 16SrIII, 16SrVIIand 16SrXIII) have been detected in Argentina infecting more than 20 plant species.The X-disease (16SrIII) is one of the most spread phytoplasma group; not only it isrepresented by a high number of subgroups, but it has also a wide host range. Amongthe 16SrIII subgroups described, -B, -J and two new subgroups -W and ?X have beenreported. Also new phytoplasmas have been identified belonging to 16SrI-B and ?S(new subgroup), 16SrVII-B and -C and 16SrXIII-C subgroups. Epidemiological studiesshow that phytoplasmas in important crops such as garlic and alfalfa are present withhigh prevalence and low incidence. The transmission of the agent associated with alfalfawitches? broom (ArAWB) is being studied under controlled conditions. Genes encodingimmunodominant membrane proteins were identified in this local phytoplasma genomeand specific antisera against proteins potentially involved in phytoplasma-host interactionsare being produced.
