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 کاملErwinia oleae sp. nov., isolated from olive knots caused by Pseudomonas savastanoi pv. savastanoi.
Three endophytic bacterial isolates were obtained in Italy from olive knots caused by Pseudomonas savastanoi pv. savastanoi. Phenotypic tests in combination with 16S rRNA gene sequence analysis indicated a phylogenetic position for these isolates in the genera Erwinia or Pantoea, and revealed two other strains with highly similar 16S rRNA gene sequences (>99 %), CECT 5262 and CECT 5264, obtaine...
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 کاملDraft Genome Sequence of Erwinia toletana, a Bacterium Associated with Olive Knots Caused by Pseudomonas savastanoi pv. Savastanoi
Erwinia toletana was first reported in 2004 as a bacterial species isolated from olive knots caused by the plant bacterium Pseudomonas savastanoi pv. savastanoi. Recent studies have shown that the presence of this bacterium in the olive knot environment increases the virulence of the disease, indicating possible interspecies interactions with P. savastanoi pv. savastanoi. Here, we report the fi...
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...
