Abstract
In May 2016, leaf spot symptoms were observed on five-year-old common fig trees, located in Sari County (Mazandaran Province). Symptoms comprised irregular and brown necrotic spots, surrounded by yellow halos. Yellow-coloured, mucoid bacterial colonies were consistently isolated from the infected samples. Bacterial isolates were identified by using biochemical, molecular and pathogenicity assays. All isolates showed identical biochemical characteristics typical of the genus Pantoea. Furthermore, based on the nucleotide sequence of 16S rRNA and gyrB genes, the causal agent was identified as Pantoea agglomerans. Upon artificial inoculations under greenhouse conditions, the isolated strains caused symptoms in mature leaves of common fig saplings. To the best of our knowledge, this is the first worldwide report of P. agglomerans causing bacterial leaf spot on common fig.
期刊介绍：
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
