Phytoplasma Diseases of Forest Trees     pdf     HR     EN 155
Summary: Phytoplasmas, formerly called mycoplasmalike organisms (MLOs) have been known to be the causal agents of plant diseases since 1967 (Doi i sur. 1967). So far phytoplasmas have been isolated from more than 600 plant species. Phytoplasmas, mycoplasmas and spiroplasmas are similar organisms which represent the smallest free-living procaryotes. These three microorganisms lack a rigid cell wall and are bound only by a triple-layer unit membrane. They are very pleomorphic. Phytoplasmas and spiroplasmas occur mostly in the phloem tissue of plants. Syndromes of phytoplasmas and spiroplasmas are phyllody, virescense and dwarfing. Phytoplasmas have been detected in forest trees belonging to at least 25 genera. Most of the trees are only slightly affected and tolerate the infection until other interacting stress factors cause loss of vigour and dieback. Earlier phytoplasma detection and identification were based on electron and fluorescence microscopy. However, nowadays detection and identification are possible by several DNA-based techniques, among which those involving the polymerase chain reaction (PCR) have become very popular because of high sensitivity.
Key words: forest trees; phytoplasmas; spiroplasmas
