Chemotaxis 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 کاملMolecular characterization and expression analysis of the anthranilate synthase gene of Pseudomonas syringae subsp. savastanoi.
The trpE gene, which encodes the large component of the enzyme anthranilate synthase, was isolated from a Pseudomonas syringae subsp. savastanoi (P. savastanoi) cosmid library. Cosmids that complemented an Escherichia coli trpE mutation contained a gene whose product is 86% homologous at the deduced amino acid level to TrpE of Pseudomonas aeruginosa and Pseudomonas putida. Amino acid sequence c...
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 کاملCloning of the glutamyl-tRNA synthetase (gltX) gene from Pseudomonas aeruginosa.
The glutamyl-tRNA synthetase (gltX) gene from Pseudomonas aeruginosa was identified. A plasmid containing a 2.3-kb insert complemented the temperature-sensitive gltX mutation of Escherichia coli JP1449, and GltX activity was demonstrated. The inferred amino acid sequence of this gene showed 50.6% identity with GltX from Rhizobium meliloti.
متن کاملCharacterization of the hrpZ gene from Pseudomonas syringae pv. maculicolaM2
Pseudomonas syringae pv. maculicola is a natural pathogen of members of the Brassicaceae plant family. Using a transposon-based mutagenesis strategy in Pseudomonas syringaepv. maculicola M2 (PsmM2), we conducted a genetic screen to identify mutants that were capable of growing in M9 medium supplemented with a crude extract from the leaves of Arabidopsis thaliana. A mutant containing a transposo...
