Crops of the Solanaceae family are essential crops in the human diet and are grown worldwide. They are infected by many pathogens, which can cause various diseases, the most important of which is bacterial soft rot, which is considered among the most critical and complex diseases due to its economic importance in the field and storage. Pantoea agglomerans, formerly Enterobacter agglomerans, are among the most common bacterial pathogens. It infects a wide range of crops and plants with various diseases, including bacterial soft rot of onion, Chinese cabbage, and Chinese yam and wilt, gall, and blight diseases in other crops. Pathogenicity tests were conducted on samples collected from greenhouse crops of tomato and pepper. In addition to those obtained from local markets, which showed soft rot symptoms, five isolates were identified to cause soft rot disease. Isolate Pa3 outperformed the rest of the isolates in terms of speed of symptom appearance and severity of virulence. The isolate tested negative for Gram stain but tested positive for KOH, catalase, gelatin liquefaction, oxidation-fermentation, and motility tests. It was negative for indole production and oxidation tests based on biochemical analyses. Nucleotide sequence analysis of 16S ribosomal RNA result confirmed a 100% similarity rate and was registered in NCBI under the accession number (OR690734). [ABSTRACT FROM AUTHOR] |
