Abstract Bactrocera zonata is a fruit tree pest that typically attacks and causes heavy damage in production using its sucking mouth. Researchers have started to distinguish them through molecular characterization sequencing control this pest. Mitochondrial genes such as COI (mtCOI) are commonly used barcoding for identifying eukaryotes counting insects. In the current study, mtCOI gene has bee...

In order to control Pectobacterium carotovorum subsp. carotovorum, a novel virulent bacteriophage PM2 was isolated. Bacteriophage PM2 can infect 48% of P. carotovorum subsp. carotovorum and 78% of P. carotovorum subsp. brasilliensis but none of atrosepticum, betavasculorum, odoriferum and wasabiae isolates had been infected with PM2. PM2 phage belongs to the family Myoviridae, and contains a la...

Pectobacterium carotovorum subsp. carotovorum is a well-known plant pathogen that causes severe soft rot disease in various crops, resulting in considerable economic loss. To identify pathogenicity-related factors, Chinese cabbage was inoculated with 5314 transposon mutants of P. carotovorum subsp. carotovorum Pcc21 derived using Tn5 transposon mutagenesis. A total of 35 reduced-virulence or av...

The bacterial and archaeal CRISPR/Cas adaptive immune system targets specific protospacer nucleotide sequences in invading organisms. This requires base pairing between processed CRISPR RNA and the target protospacer. For type I and II CRISPR/Cas systems, protospacer adjacent motifs (PAM) are essential for target recognition, and for type III, mismatches in the flanking sequences are important ...

Bacterial pathogens need to scavenge iron from their host for growth and proliferation during infection. They have evolved several strategies to do this, one being the biosynthesis and excretion of small, high-affinity iron chelators known as siderophores. The biosynthesis of siderophores is an important area of study, not only for potential therapeutic intervention but also to illuminate new e...

Recent methodological developments have uncovered the etiological diversity of potato blackleg and soft rot Pectobacteriaceae. At least five species in genera Dickeya Pectobacterium been confirmed to cause on potatoes Finland. The bacteria are seed borne remain latent tuber until conditions favourable for growth, multiplication infection prevail. Tubers could be infected by one or more these sp...

The moth orchid (Phalaenopsis sp.) is one of the most popular orchids due to various colors with distinctive shapes flowers. Soft rot disease caused by Pectobacteriaceae (SRP) family commonly found infected this plant. showed pale-colored blackish slimy rot. This research was conducted in three locations namely Denpasar, Badung, and Karangasem, resulted 10 candidates for pathogenic bacteria. pa...

Krejzar V., Mertelík J., Pánková I., Kloudová K., Kůdela V. (2008): Pseudomonas marginalis associated with soft rot of Zantedeschia spp. Plant. Protect. Sci., 44: 85–90. For the first time in the Czech Republic, bacteria identified as Pseudomonas marginalis, Pectobacterium carotovorum subsp. carotovorum and Pseudomonas putida were isolated from tubers of Zantedeschia spp. with symptoms of tuber...
