<i>Pseudomonas viridiflava</i> Causing Leaf Spot of Common Mallow in Iran
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.
