On Some Significant Phytoplasma Diseases of Forest Trees: An Update

This paper provides an updating of information a selected number major phytoplasma diseases forest trees, with focus on the associated taxa. Phytoplasma trees have been less extensively studied than those affecting fruit trees. Research role phytoplasmas as cause has only in last few years intensified, after sensitive and specific detection methods greatly based PCR technology became available. Various taxa identified naturally infected elm, ash, conifer, sandal, eucalyptus whereas one taxon recorded alder However, for almost all reviewed diseases, there is still sparse about insect vectors, plant host range, strain virulence, pathogenicity, tolerance resistance. Knowledge these aspects basis appropriate disease management. In particular, further research required to clarify asymptomatic addition, etiological various “non-specific” taxa, which while no data from pathological studies are available, needs be investigated.
