HIGHLIGHTS
  • Potato ranks first among the non-cereal crops in terms of human consumption
  • Soft rot of potato caused by Pseudomonas marginalis as a threat to potato industry
  • Confirm the presence of Pseudomonas marginalis, causative agent of soft rot disease of potato in Iran
  • Identification of the bacterial isolates on the basis of phenotypic/biochemical characteristics, pathogenicity assay and phylogenetic features

ABSTRACT
In 2016, potato tuber soft rot symptoms were observed in major potato production fields in Jiroft county (southern Kerman province, Iran). Bacteria, which appeared as white to creamy colonies, were isolated from diseased tissues and shown to be pathogenic on potato tubers after inoculation and re-isolation of the isolates. Based on the assessment of colony morphology, biochemical characteristics, and analysis of 16S rRNA and gyrB gene sequences, the pathogen was identified as Pseudomonas marginalis. To our knowledge, this is the first report of P. marginalis causing potato tuber soft rot disease in Iran.
