Sažetak
Phytoplasmas have been known for decades to be important plant pathogens. Due to their morphological similarity with mycoplasmas, they were formerly called mycoplasmalike organisms. They differ from a vast majority of bacteria by the absence of a cell wall which enables them to shift from spherical to filamentous shape. The cultivation of these pleomorphic microorganisms on artificial media is not possible, which makes their investigation extremely difficult. So far, phytoplasmas have been isolated from more than 600 plant species belonging to a number of different families. The most frequently encountered symptoms of phytoplasmoses are leaf yellowing, virescence (greening of floral organs) and flower sterility, as well as witches’ broom caused by strong proliferation of axillary buds. Phytoplasmas are readily transmitted by vectors and grafting. They are causal agents of severe diseases in crops, horticultural species and forest trees. Phytoplasmoses of great economic importance are grapevine yellows identified also in Croatia as a factor of significant losses in viticulture. Laboratory for Plant Virology of the Department of Biology, University of Zagreb, introduced modern molecular biology methods for a routine detection and identification of these phytopathogens. The development of new molecular approaches will improve detection and enable in depth-investigation of phytoplasma genes presumed to be important for the plant-pathogen interactions.
