Clavibacter toxicus sp. nov., the Bacterium Responsible for Annual Ryegrass Toxicity in Australia
The Clavibacter sp. associated with annual ryegrass toxicity (ARGT) in Australia has been reported to differ from other Clavibacter spp. in serological properties, allozyme electrophoretic mobility,Expand

Evolution of the gall-forming plant parasitic nematodes (Tylenchida: Anguinidae) and their relationships with hosts as inferred from Internal Transcribed Spacer sequences of nuclear ribosomal DNA.
Phylogenetic relationships among gall-forming plant parasitic nematodes of the subfamily Anguininae are reconstructed by maximum parsimony and maximum likelihood analyses. Sequences of the ITS ofExpand

Serological Relationships between Strains of Coryneform Bacteria Responsible for Annual Ryegrass Toxicity and Other Plant-Pathogenic Corynebacteria
Immunodiffusion and an enzyme-linked immunosorbent assay (ELISA) were used to reveal serological relationships between coryneform bacteria responsible for annual ryegrass toxicity (ARGT) and otherExpand

Genetic Characterization and Diversity of Rathayibacter toxicus.
ABSTRACT Rathayibacter toxicus is a nematode-vectored gram-positive bacterium responsible for a gumming disease of grasses and production of a highly potent animal and human toxin that is often fatalExpand

Specificity of the adhesion of some plant pathogenic micro-organisms to the cuticle of nematodes in the genus Anguina (Nematoda: Anguinidae).
The adhesion of Dilophospora alopecuri conidia from two host species and 35 strains of plant pathogenic corynebacteria to seven populations of seed-gall nematodes, Anguina spp., was investigated. TheExpand

The Mitochondrial Subgenomes of the Nematode Globodera pallida Are Mosaics: Evidence of Recombination in an Animal Mitochondrial Genome
We sequenced four mitochondrial subgenomes from the potato cyst nematode Globodera pallida, previously characterized as one of the few animals to have a multipartite mitochondrial genome. TheExpand

Endoparasitic nematodes in cropping soils of Western Australia
Soil samples were collected in Western Australia from cereal fields at about harvest time to determine levels of the endoparasitic nematodes, Pratylenchus and Heterodera. A systematic survey in 1997Expand

Characterization of resistance to Pratylenchus thornei (Nematoda) in wheat (Triticum aestivum): attraction, penetration, motility, and reproduction.
Lines from a cross between two wheat (Triticum aestivum) cultivars with contrasting resistance phenotypes to Pratylenchus thornei (Nematoda) were investigated to determine the stage at whichExpand
