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 کاملGlobal genomic analysis of Pseudomonas savastanoi pv. savastanoi plasmids.
Pseudomonas savastanoi pv. savastanoi strains harbor native plasmids belonging to the pPT23A plasmid family (PFPs) which are detected in all pathovars of the related species Pseudomonas syringae examined and contribute to the ecological and pathogenic fitness of their host. However, there is a general lack of information about the gene content of P. savastanoi pv. savastanoi plasmids and their ...
متن کاملChemotaxis of Pseudomonas syringae subsp. savastanoi Virulence Mutants.
Several mutants of Pseudomonas syringae subsp. savastanoi were tested for their ability to sense and respond to a chemotactic gradient in low concentrations of yeast extract. The mutants were deficient in one or both of the genes coding for the synthesis of the plant hormones indole-3-acetic acid (IAA) and isopentenyl adenosine. Mutations which resulted in the loss of IAA production were due to...
متن کاملDraft Genome Sequence of Erwinia oleae, a Bacterium Associated with Olive Knots Caused by Pseudomonas savastanoi pv. savastanoi
Erwinia oleae is a nonpathogenic bacterial species isolated from olive knots caused by Pseudomonas savastanoi pv. savastanoi. Since the presence of E. oleae in the knots increases disease severity, interspecies interactions with the pathogen are hypothesized. Here, we report the first draft genome sequence of the E. oleae type strain.
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...
