Compatibility between Pasteuria penetrans isolates and Meloidogyne populations from Spain
Espanol, M.; VerdejoLucas, S.; Davies, Keith; Kerry, Brian R. (1997-06)Several populations of Pasteuria isolated from fields in Spain were compared with other Pasteuria populations, held in collections at the Institute de Recerca i Tecnologia, Agroalimentaries (IRTA), Cabrils or IACR-Rothamsted, ... -
Exploitation of immunofluorescence for the quantification and characterization of small numbers of Pasteuria endospores
Costa, Sofia R.; Kerry, Brian R.; Bardgett, Richard D.; Davies, Keith G. (2006-12)The Pasteuria group of endospore-forming bacteria has been studied as a biocontrol agent of plant-parasitic nematodes. Techniques have been developed for its detection and quantification in soil samples, and these mainly ... -
Identification of New Single Nucleotide Polymorphism-Based Markers for Inter- and Intraspecies Discrimination of Obligate Bacterial Parasites (Pasteuria spp.) of Invertebrates
Mauchline, Tim H.; Knox, Rachel; Mohan, Sharad; Powers, Stephen J.; Kerry, Brian R.; Davies, Keith G.; Hirsch, Penny R. (2011-09)Protein-encoding and 16S rRNA genes of Pasteuria penetrans populations from a wide range of geographic locations were examined. Most interpopulation single nucleotide polymorphisms (SNPs) were detected in the 16S rRNA gene. ... -
Interactions between nematodes and their microbial enemies in coastal sand dunes
Costa, Sofia R.; Kerry, Brian R.; Bardgett, Richard D.; Davies, Keith G (2012)European foredunes are almost exclusively colonised by Ammophila arenaria, and both the natural succession and the die-out of this plant have been linked to populations of plant-parasitic nematodes (PPN). The overarching ... -
The life-cycle and pathology of the root-knot nematode parasite Pasteuria-Penetrans
Davies, Keith; Flynn, C. A.; Kerry, Brian R. (British Crop Protection Council, 1988) -
A method for release and multiple strand amplification of small quantities of DNA from endospores of the fastidious bacterium Pasteuria penetrans
Mauchline, Tim H.; Mohan, Sharad; Schaff, J. E.; Opperman, Charles H.; Kerry, Brian R.; Davies, Keith; Hirsch, Penny R. (2010-05)Aims: To establish a reliable protocol to extract DNA from Pasteuria penetrans endospores for use as template in multiple strand amplification, thus providing sufficient material for genetic analyses. To develop a highly ... -
Microbial agents for the biological control of plant-parasitic nematodes in tropical agriculture
Davies, Keith; Deleij, F. A. A. M.; Kerry, Brian R. (1991) -
Observations on the pathogenicity of pasteuria-penetrans, a parasite of root-knot nematodes
Davies, Keith; Kerry, Brian R.; Flynn, C. A. (1988-06)A simple test was used to determine whether or not Pasteuria penetrans spores would attach to 17 species of nematodes. All susceptible individuals had spores attached to their cuticles after 24 h of gentle agitation in ... -
Phylogenetic analysis of Pasteuria penetrans by use of multiple genetic loci
Charles, L.; Carbone, I.; Davies, Keith; Bird, D.; Burke, M.; Kerry, Brian R.; Opperman, Charles H. (2005-08)Pasteuria penetrans is a gram-positive, endospore-forming eubacterium that apparently is a member of the Bacillus-Clostridium clade. It is an obligate parasite of root knot nematodes (Meloidogyne spp.) and preferentially ... -
The Pochonia chlamydosporia Serine Protease Gene vcp1 Is Subject to Regulation by Carbon, Nitrogen and pH : Implications for Nematode Biocontrol
Ward, Elaine; Kerry, Brian R.; Manzanilla-Lopez, Rosa H.; Mutua, Gerald; Devonshire, Jean; Kimenju, John; Hirsch, Penny R. (2012-04-27)The alkaline serine protease VCP1 of the fungus Pochonia chlamydosporia belongs to a family of subtilisin-like enzymes that are involved in infection of nematode and insect hosts. It is involved early in the infection ...
