Identifikacija i karakterizacija bakterije Pseudomonas syringae patogena breskve

Pseudomonas syringae is economically important plant pathogen, found on a number of hosts including fruit trees, field crops, vegetables and decorative plants. This phytopathogenic bacteria is becoming a quite widespread pathogen on the fruit trees in Serbia, causing significant economic loses. Up to now it was experimentally confirmed as a pathogen on the pear, apple, apricot, cherry, sour cherry, plum trees as well as raspberries. In this study Pseudomonas syringae was identificated as pathogen on peach tree in Serbia. Detection of syrB gene was used for identification phytotoxins tipical for P. syringae pv. syringae. Our experiment showed that detection of syrB genes can be used as a diagnostic tool in determining pathovars of Pseudomonas syringae parasites on peach trees. Pseudomonas syringae ekonomski značajan biljni patogen širokog kruga domaćina koji uključuje voćke, ratarske, povrtarske i ukrasne biljke. Ova fitopatogena bakterija naročitu pažnju privlači kao patogen voćaka prouzrokujući sve veće štete. Do sada je eksperimentalno potvrđen kao parazit kruške, jabuke, kajsije, trešnje, višnje, šljive i maline. Pseudomonas syringae je identifikovan kao patogen breskve u Srbiji. Detekcija syrB gen je korišćena za identifikaciju fitotoksina karakterističnog za P. syringae pv. syringae. Naš je eksperiment pokazao da se detekcijom SyrB gena kao dijagnostičkog alata može identifikovati patogeni varijetet patogen breskve.
