Sažetak
Olive knot disease or olive tuberculosis is caused by pathogenesis of gram-negative bacterium Pseudomonas savastanoi pv. savastanoi (Pss). Pss is a species that belongs to the complex of Pseudomonas savastanoi/Pseudomonas syringae along with some other economically signifi cant pathovars. The mechanism of Pss pathogenesis includes synthesis of two growth hormones – auxins and cytokinins that causes the appearance of hypertrophic tissue on the diff erent plant organs of olive tree (Olea europaea L.). Most often, these growths or knots forms on the branches and leaf stem, and when the infection is severe knots are present on the trunk, leaves and fruits. The presence of olive knot disease has been recorded in almost all olive growing regions in the world. Therefore, for the purpose of this study, fi eld research and sampling of infected plant material from Istrian growing region was performed in year 2021. A total of 92 samples were collected from 39 diff erent locations in Croatian Istria. Samples were collected from diverse olive varieties grown in diff erent production systems. The presence of pathogen was determined by molecular method Real-Time PCR. Results shown that Pss, the causal agent of olive knot disease was detected in 24% of tested samples. The highest number of positive samples was determined on ‘Leccino’ variety (40%) followed by ‘Frantoio’ (22%).
