Cloning of a mineral phosphate-solubilizing gene from Pseudomonas cepacia.
We have recently shown that the ability of some gram-negative bacteria to dissolve poorly soluble calcium phosphates (Mps+ phenotype) is the result of periplasmic oxidation of glucose to gluconic acid via the quinoprotein glucose dehydrogenase (GDH), a component of the direct oxidation pathway. Escherichia coli K-12 derivatives synthesize apo-GDH but not the cofactor pyrroloquinoline-quinone (P...
متن کاملExpression of a mineral phosphate solubilizing gene from Erwinia herbicola in two rhizobacterial strains.
A genetic construction was carried out using the broad host range vector pKT230 and plasmid pMCG898, which encodes the Erwinia herbicola pyrroloquinoline quinone (PQQ) synthase, a gene involved in mineral phosphate solubilization (mps). The final construction was transformed and expressed in Escherichia coli MC1061, and the recombinant plasmids were transferred to Burkholderia cepacia IS-16 and...

toxin produced by fungi in the genera Fusarium and Gibber-ella.lf2) It alters the permeability of plant cytoplasmic membranesto water and causes solute leakage from tomato leaves.3A) It also chelate copper and other ions that could be involved in maintaining membrane integrity5'^ and affects membrane potentials and ATP levels of tomato root hair cells.7) Recently, it has been found that tomato ...
متن کاملProspects of Using Phosphate Solubilizing Pseudomonas as Bio Fertilizer
Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...
متن کاملPseudomonas lutea sp. nov., a novel phosphate-solubilizing bacterium isolated from the rhizosphere of grasses.
A phosphate-solubilizing bacterial strain designated OK2(T) was isolated from rhizospheric soil of grasses growing spontaneously in a soil from Spain. Cells of the strain were Gram-negative, strictly aerobic, rod-shaped and motile. Phylogenetic analysis of the 16S rRNA gene indicated that this bacterium belongs to the gamma-subclass of Proteobacteria within the genus Pseudomonas and that the cl...
