Abstract
In the spring 2018, a leaf disease including light and necrotic spots with irregular edges surrounded by chlorotic halos was detected on common mallow in Jiroft County (Kerman Province, Iran). A bacterium-forming cream-coloured and mucoid colonies on King's B agar medium was consistently isolated and was fitting of the traits of the genus Pseudomonas. Isolated strains caused spots on common mallow leaves in the pathogenicity test that was identical to natural field symptoms and belonged to Pseudomonas viridiflava based on phenotypic characteristics including LOPAT tests. Two representative isolates were further confirmed as P. viridiflava with 99% sequence identity after sequencing the 16S rRNA and gyrB genes. To our knowledge, this is the first report of P. viridiflava causing leaf spot disease on common mallow in Iran.
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.
