Crown gall of cherry trees (Prunus avium L.) is mainly caused by the pathogenic bacteria Rhizobium radiobacter carrying the tumor-inducing (Ti) plasmids. The causal agent has a controversial taxonomy suffering different nomenclature changes based on the biochemical and genetic discoveries over the time. At first, this pathogenic bacterium was known as Agrobacterium biovar 1 or Agrobacterium tumefaciens, and currently as Rhizobium radiobacter carrying the Ti plasmid. The aim of this study was to identify the causal agent responsible for the crown gall symptoms of young cherry trees. Analyzed plants were provided from young orchards from Călărai County, between 2015 and 2019. The pathogen was foreseen based on its characteristic disease symptoms. However, pathogen identification was sustained by several microbiologic and biochemical tests and confirmed through Biolog GEN III technique. The pathogenicity test has revealed the isolated strains' virulence. Some other bacterial species were also associated with tumors. [ABSTRACT FROM AUTHOR] |
