Biocontrol of Pythium in the pea rhizosphere by antifungal metabolite producing and non-producing Pseudomonas strains
Naseby, D.C.; Way, J.; Bainton, N.; Lynch, J.M. (2001)Four well-described strains of Pseudomonas fluorescens were assessed for their effect upon pea growth and their antagonistic activity against large Pythium ultimum inocula. The effect of Pseudomonas strains upon the ... -
Carbon fractions in the rhizosphere of pea inoculated with 2,4 diacetylphloroglucinol producing and non-producing Pseudomonas fluorescens F113
Naseby, D.C.; Pascual, J.A.; Lynch, J.M. (1999)The aim of this work was to determine the effect of wild type and functionally modified Pseudomonas fluorescens strains on C fractions in the rhizosphere of pea. The lacZY marked F113 strain produces the antibiotic 2,4 ... -
Effect of 2,4-Diacetylphloroglucinol Producing, Overproducing, and Nonproducing Pseudomonas fluorescens F113 in the Rhizosphere of Pea
Naseby, D.C.; Lynch, J.M. (2001) -
Effect of biocontrol strains of Trichoderma on plant growth, Pythium ultimum populations, soil microbial communities and soil enzyme activities
Naseby, D.C.; Pascual, J.A.; Lynch, J.M. (2000) -
Effect of cadmium contamination with sewage sludge and phosphate fertiliser amendments on soil enzyme activities, microbial structure and available cadmium
Karaca, A.; Naseby, D.C.; Lynch, J.M. (2002) -
Effects of Pseudomonas fluorescens F113 on Ecological Functions in the Pea Rhizosphere Are Dependent on pH
Naseby, D.C.; Lynch, J.M. (1999)The aim of this microcosm study was to determine influence of the antibiotic 2,4 diacetylphloroglucinol (DAPG) on the effect of wild type and functionally modified Pseudomonas fluorescens F113 strains in a sandy loam soil ... -
Establishment and impact of Pseudomonas fluorescens genetically modified for lactose utilization and kanamycin resistance in the rhizosphere of pea
Naseby, D.C.; Lynch, J.M. (1998)The impact of a Pseudomonas fluorescens strain, genetically modified for kanamycin resistance and lactose utilisation (the GMM), could be enhanced by soil amendment with lactose and kanamycin. Lactose addition decreased ... -
Functional impact of genetically modified micro-organisms on the soil ecosystem
Naseby, D.C.; Lynch, J.M. (SOS Publications, 1997)Most attempts to monitor the effects of introductions of Genetically Modified Micro-organisms (GMMs) have centred on the enumeration of specific populations. However for a significant perturbation to be measured, changes ... -
Impact of wild-type and genetically modified Pseudomonas fluorescens on soil enzyme activities and microbial population structure in the rhizosphere of pea
Naseby, D.C.; Lynch, J.M. (1998)The aim of this work was to determine the impact of wild type along with functionally and non-functionally modified Pseudomonas fluorescens strains in the rhizosphere. The wild type F113 strain carried a gene encoding the ... -
Rhizosphere soil enzymes as indicators of perturbations caused by enzyme substrate addition and inoculation of a genetically modified strain of Pseudomonas fluorescens on wheat seed
Naseby, D.C.; Lynch, J.M. (1997)Comparative assays for determining chitobiosidase, N-acetyl glucosaminidase, acid phosphatase, alkaline phosphatase, phosphodiesterase, aryl 2 sulfatase and urease activities from small samples of soil were developed. The ... -
Soil enzyme activities in the rhizosphere of field-grown sugar beet inoculated with the biocontrol agent Pseudomonas fluorescens F113
Naseby, D.C.; Moenne-Loccoz, Y.; Powell, J.; O'Gara, F.; Lynch, J.M. (1998)Pseudomonas fluorescens F113, which produces the antimicrobial compound 2,4-diacetylphloroglucinol is a prospective biocontrol agent. Soil enzyme activities were used to investigate the ecological impact of strain F113 in ... -
Survival and ecological fitness of Pseudomonas fluorescens genetically engineered with dual biocontrol mechanisms
Bainton, N.; Lynch, J.M.; Naseby, D.C.; Way, J. (2004)
