We report here the isolation and analysis of novel repA host range mutants of pPS10, a plasmid originally found in Pseudomonas savastanoi. Upon hydroxylamine treatment, five plasmid mutants were selected for their establishment in Escherichia coli at 37 degrees C, a temperature at which the wild-type form cannot be established. The mutations were located in different functional regions of the p...

Aim of study: To evaluate the virulence and indole-3-acetic acid (IAA) biosynthesis ability several Turkish P. savastanoi pv. isolates susceptibility some native genotypes to olive knot.
 Area The Aegean, Marmara, Mediterranean Regions Turkey.
 Material methods: 101 isolated bacteria were identified on basis biochemical, PCR for amplification bacterial iaaL gene, pathogenicity tests. ...

We have been isolating and characterizing Ralstonia solanacearum-responsive genes (RsRGs) in Nicotiana plants. In this study we focused on RsRG308, which we renamed NbTCTP (N. benthamiana translationally controlled tumor protein) because it encodes a polypeptide showing similarity to translationally controlled tumor proteins. Induction of the hypersensitive response (HR) was accelerated in NbTC...

Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. The search for new pest and disease control methods based on bioantagonist microorganisms is an important aspect...
