  ABSTRACT Plants can be induced to develop enhanced resistance to pathogen infection by treatment with a variety of abiotic and biotic inducers. Biotic inducers include infection by necrotizing pathogens and plant-growth-promoting rhizobacteria, and treatment with nonpathogens or cell wall fragments. Abiotic inducers include chemicals which act at various… (More)
  Host-Pathogen Interactions : XXV. Endopolygalacturonic Acid Lyase from Erwinia carotovora Elicits Phytoalexin Accumulation by Releasing Plant Cell Wall Fragments.
  K R Davis, G D Lyon, A G Darvill, P Albersheim
  Heat-labile elicitors of phytoalexin accumulation in soybeans (Glycine max L. Merr. cv Wayne) were detected in culture filtrates of Erwinia carotovora grown on a defined medium containing citrus pectin as the sole carbon source. The heat-labile elicitors were highly purified by cation-exchange chromatography on a CM-Sephadex (C-50) column, followed by… (More)
  Infection of leaves of Arabidopsis thaliana by Botrytis cinerea: changes in ascorbic acid, free radicals and lipid peroxidation products.
  I Muckenschnabel, B A Goodman, B Williamson, G D Lyon, N Deighton
  Infection of leaves of Arabidopsis thaliana with conidial suspensions of the necrotrophic pathogen Botrytis cinerea resulted in a large decrease in the level of ascorbic acid and increases in intensity of a single-peak free radical and Fe(III) (g=4.27) signals in electron paramagnetic resonance (EPR) spectra. These changes were not confined to the spreading… (More)

  The role of active oxygen species has been studied in spreading soft-rot lesions caused by the necrotrophic fungal pathogen Botrytis cinerea Pers.:Fr. in leaves of four genotypes of French bean (Phaseolus vulgaris L.). Large increases were observed for the aldehydic end-products of oxidative damage, malondialdehyde and 4-hydroxy-2-nonenal, as a result of… (More)

  Agrobacterium transformation systems forBrassica, Solanum andRubus, using carbenicillin, cefotaxime and ticaracillin respectively to eliminate contamination, were examined for the presence of residualAgrobacterium. The results indicated that none of the antibiotics in question, succeeded in eliminatingAgrobacterium and the contamination levels increased in… (More)
  Responses of cells and protoplasts of Coffea arabica genotypes to partially purified culture filtrates produced by Colletotrichum kahawae
  N. E. Nyange, B. Williamson, G. D. Lyon, R. J. McNicol, T. Connolly
  Hypocotyl-derived calli of genotypes and segregating populations of Coffea arabica, differing in susceptibility to Colletotrichum kahawae, were used to produce cell suspensions and protoplasts which were exposed to partially purified culture filtrates (PPCFs) prepared from the pathogen. The growth and viability of PPCF-treated cells and protoplasts were… (More)

  Evidence is presented that a number of mechanisms are involved in the resistance of commercial cultivars of potato to soft rottingErwinia spp. These include phytoalexins, phenolics, cell wall modification, and possibly proteins. The role of elicitor-active oligogalacturonides, which are released from plant cell walls by pectic enzymes, is discussed.
