Recent developments in Pseudomonas biocontrol mechanisms
Fluorescent pseudomonads are an effective source of biological control that have high adaptive power and able to produce a wonderful source of secondary metabolites. Antibiotics such as phenazines, diacetylphloroglucinol, and hydrogen cyanide are produced by certain taxonomic groups of the genus Pseudomonas and appear to be ancestral. These compounds often play a physiological role in the produ...
متن کاملIdentification of Some Molecular Traits in Fluorescent Pseudomonads with Antifungal Activity
We assessed a collection of 47 fluorescent Pseudomonas spp., some with known biological control activity against certain soil-borne phytopathogenic fungi such as, Macrophomina phaseolina, Rhizoctonia solani, Phytophthora nicotianae var. parasitica, Pythium sp. and Fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, HCN and protease. The resu...
متن کاملThe bacterial oxidation of tryptophan. III. Enzymatic activities of cell-free extracts from bacteria employing the aromatic pathway.
Analysis of the adaptive patterns of many tryptophan-oxidizing pseudomonads indicates that a majority of these organisms metabolize tryptophan via kynurenine, anthranilic acid, and catechol-the so-called "aromatic pathway" (Stanier, Hayaishi, and Tsuchida, 1951). In order to confirm the existence of this pathway, we have undertaken a study of the enzymatic activities of cellfree extracts. Only ...
متن کاملTransmissible plasmid coding early enzymes of naphthalene oxidation in Pseudomonas putida.
The capacity of Pseudomonas putida PpG7 (ATCC 17,485) to grow on naphthalene, phenotype Nah(+), is lost spontaneously, and the frequency is increased by treatment with mitomycin C. The Nah(+) growth character can be transferred to cured or heterologous fluorescent pseudomonads lacking this capacity by conjugation, or between phage pf16-sensitive strains by transduction. After mutagenesis, strai...
متن کاملThe Pseudomonas putida Crc global regulator controls the expression of genes from several chromosomal catabolic pathways for aromatic compounds.
The Crc protein is involved in the repression of several catabolic pathways for the assimilation of some sugars, nitrogenated compounds, and hydrocarbons in Pseudomonas putida and Pseudomonas aeruginosa when other preferred carbon sources are present in the culture medium (catabolic repression). Crc appears to be a component of a signal transduction pathway modulating carbon metabolism in pseud...
