The study concentrates on: investigation of the biological properties and role of agrocin 434 and other factors in the bicontrol process of crown gall disease; isolation of the complete range of K84 derivatives carrying different combinations of plasmids pAgK84, pAgK434 and pAtK84b in the same host background; development of a rapid plant bioassay to assess the efficacy of biocontrol strains by leaf disc tumorigenesis assay; and characterization of agrocin 434 synthesis and immunity genes.

This thesis examines the possible role in the biological control process, of an antibiotic compound agrocin 434, produced by biocontrol strains, in addition to the well-characterized adenine nucleotide, agrocin 84. / Thesis (Ph.D.)--University of Adelaide, Dept. of Crop Protection and Plant Science, 1996

It centres upon the discovery and structural analysis of a previously unknown antibiotic substance known as agrocin 434. This agrocin is produced by A. rhizogenes (formerly "radiobacter") strain K84, the biological control agent of crown gall. / Thesis (Ph.D.)--University of Adelaide, Dept. of Plant Science, 1997
