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 کاملAuxin production is a common feature of most pathovars of Pseudomonas syringae.
We investigated indole-3-acetic acid (IAA) production by 57 pathovars of Pseudomonas syringae and related species. Most of those analyzed produced IAA, especially in the presence of tryptophan. Eight strains produced high IAA concentrations in the absence of Trp. The iaaM and iaaH genes of P. savastanoi pv. savastanoi were detected in a limited number of strains only, including the eight above-...
متن کاملComparative genomics of Pseudomonas syringae pv. syringae strains B301D and HS191 and insights into intrapathovar traits associated with plant pathogenesis
Pseudomonas syringae pv. syringae is a common plant-associated bacterium that causes diseases of both monocot and dicot plants worldwide. To help delineate traits critical to adaptation and survival in the plant environment, we generated complete genome sequences of P. syringae pv. syringae strains B301D and HS191, which represent dicot and monocot strains with distinct host specificities. Intr...
