  • Fitoplazme na sadnem drevju = Fruit tree phytoplasmas
    Brzin, Jernej ...
    Phytoplasmas are uncultivable, wall-less and the smallest known cellular organisms related to Gram positive bacteria. They live exclusively in the sieve tubes of their plant hosts and cause several ... hundred important vector-borne and graft-transmissible plant diseases. In Europe, fruit trees ofRosaceae family are seriously affected by phytoplasmas of apple proliferation group (16SrX group), which include apple proliferation (AP), european stone fruit yellows (ESFY) and pear decline (PD) phytoplasma. The control of these quarantine diseases is based on prompt removal of infected plants in nurseries and orchards. Advantages and drawbacks of visual and laboratory detection will be put forward in particular regarding latent infections and delayed symptom expression in nursery stocks. Since we have recently detected phytoplasmas in cherry trees the possibility of phytoplasma aetiology of cherry tree decline observed in recent years will be discussed. Current data of fruit tree phytoplasma occurrence in Slovenia will be presented.
