Impact on Arbuscular Mycorrhiza Formation ofPseudomonas Strains Used as Inoculants for Biocontrol of Soil-Borne Fungal Plant Pathogens
TLDR
The results of scanning electron and confocal microscopy demonstrated that strain F113 and its derivatives adhered to G. mosseae spores independent of the ability to produce DAPG, a concentration that might be present in the rhizosphere. Expand
Biocontrol agents applied individually and in combination for suppression of soilborne diseases of cucumber
TLDR
These results indicate that antagonism among combinations of biocontrol agents can vary with the assay system employed and substantiate other studies reporting enhanced biocOntrol performance with certain combinations ofBiocontroll agents. Expand
Transcriptional activation of Agrobacterium tumefaciens virulence gene promoters in Escherichia coli requires the A. tumefaciens RpoA gene, encoding the alpha subunit of RNA polymerase.
TLDR
It is suggested that transcription of virulence genes requires specific interaction between VirG and thealpha subunit of A. tumefaciens and that the alpha subunit from E. coli is unable to effectively interact with the VirG protein. Expand
Transformation of Xenorhabdus nematophilus.
TLDR
A number of factors, including culture conditions, stage of growth, transformation buffer pH, cation type and concentration required for the production of competency, washing, heat shock conditions, and cell-DNA ratio, were found to affect transformation significantly. Expand
Inability to express fimbriae results in impaired ability of Haemophilus influenzae b to colonize the nasopharynx.
TLDR
A cloned into the structural fimbrial subunit gene from a fimbriated Haemophilus influenzae b a 1.5-kb kanamycin resistance gene exhibited a significant decrease in adherence to human buccal epithelial cells and in nasal colonization of yearling rhesus monkeys. Expand
Broad spectrum anti-biotic activity and disease suppression by the potential biocontrol agent Burkholderia ambifaria BC-F
TLDR
The demonstrated ability of isolate BC-F to suppress disease caused by animal and fungal pathogens of many crop plants may be due to the ability to persist for long periods in association with roots of diverse crop plants in different soils and the production of a metabolite(s) with broad spectrum anti-biotic activity. Expand
The Bradyrhizobium japonicum noeD gene: a negatively acting, genotype-specific nodulation gene for soybean.
TLDR
The cloning and characterization of the negatively acting DNA region mutated in strain D4.2-5 that is involved in the genotype-specific nodulation of soybean suggest that specific LCO signal molecules may be one of the factors influencing nodulation specificity in this symbiotic system. Expand
Mutation in cyaA in Enterobacter cloacae decreases cucumber root colonization
TLDR
Results demonstrate a role for cyaA in colonization of cucumber roots by Enterobacter cloacae and restore growth and chemotaxis on synthetic cucumber root exudate and increased cucumber seedling colonization by this strain without serving as a source of reduced carbon, nitrogen, or phosphorous. Expand
Reconstitution of acetosyringone-mediated Agrobacterium tumefaciens virulence gene expression in the heterologous host Escherichia coli.
The ability to utilize Escherichia coli as a heterologous system in which to study the regulation of Agrobacterium tumefaciens virulence genes and the mechanism of transfer DNA (T-DNA) transfer wouldExpand
Inheritance of host-controlled restriction of nodulation by Bradyrhizobium japonicum strain USDA 110
TLDR
The type of inheritance and the number of genes in PI 417566 which condition restriction of nodulation by strain USDA 110 and whether this gene(s) could function to prevent nodulation of serogroup 110 strains under field conditions were determined. Expand
