Endopathogenic lifestyle of Pseudomonas savastanoi pv. savastanoi in olive knots
The endophytic phase of Pseudomonas savastanoi pv. savastanoi in olive stems and the structural and ultrastructural histogenesis of olive knots have been studied. Construction of a stable plasmid vector expressing the green fluorescent protein, in combination with the use of in vitro olive plants, allowed real-time monitoring of P. savastanoi pv. savastanoi infection. The infection process was ...
متن کاملNucleotide sequences of the Pseudomonas savastanoi indoleacetic acid genes show homology with Agrobacterium tumefaciens T-DNA.
We report the nucleotide sequences of iaaM and iaaH, the genetic determinants for, respectively, tryptophan 2-monooxygenase and indoleacetamide hydrolase, the enzymes that catalyze the conversion of L-tryptophan to indoleacetic acid in the tumor-forming bacterium Pseudomonas syringae pv. savastanoi. The sequence analysis indicates that the iaaM locus contains an open reading frame encoding 557 ...
متن کاملBiocontrol of Pseudomonas savastanoi, causative agent of olive knot disease: antagonistic potential of non-pathogenic rhizosphere isolates of fluorescent Pseudomonas.
Olive knot, a major bacterial disease of olive plants (Olea europaea), is caused by Pseudomonas savastanoi. There is no cost-effective way to control olive knot using available chemical bactericides (Young 2004). Furthermore, development of resistance and environmental concerns urge the necessity for alternative, more selective control methods such as biological control. A potential resource fo...
متن کاملEpidemiology and Control of Plant Diseases Caused by Phytopathogenic Bacteria: The Case of Olive Knot Disease Caused by Pseudomonas savastanoi pv. savastanoi
Pseudomonas savastanoi pv. savastanoi (Gardan et al., 1992) (hereafter Psv, according to Vivian & Mansfield (1993)) is the causal agent of olive knot disease. It is considered one of the most serious diseases affecting olive trees (Olea europaea L.) in most olive growing regions worldwide and mainly in Mediterranean countries, where this crop has been growing for centuries. The disease can lead...
متن کاملRecovery of Pseudomonas savastanoi pv. savastanoi from symptomless shoots of naturally infected olive trees.
Seasonal dynamics of Pseudomonas savastanoi pv. savastanoi (Psv) on stems and leaves from symptomless shoots of naturally infected olive trees was monitored in Spanish olive orchards. Data inferred from the comparison between washing of leaves and dilution-plating versus leaf printing of individual leaves suggested that Psv population sizes varied by over several orders of magnitude, among leav...
