Role of copper resistance in competitive survival of Pseudomonas fluorescensin soil
Article Abstract:
The significance of copper resistance for the effectiveness of Pseudomonas fluorescens in the biological control of a citrus root rot disease is discussed. Three copper sensitive mutants were derived from bacterial strains and plasmids used in the study and were insertedinto a sterilized citrus grove soil and a nonsterile citrus soil. The importance of copper resistance genes in resisting Phytophthora parasitica in copper-contaminated soils was demonstrated.

Copper hypersensitivity and uptake in Pseudomonas syringae containing cloned components of the copper resistance operon
Article Abstract:
Copper sensitivity and accumulation in Pseudomonas syringae obtained with cloned components of the copper resistance operon (cop) were examined. An increased accumulation of copper was observed in cells containing several combinations of cop genes that included copC and copD. The results suggest that CopC, a periplasmic protein, and CopD, probably an inner membrane protein, may function in copper uptake.

Global effect of indole-3-acetic acid biosynthesis on multiple virulence factors of Erwinia chrysanthemi 3937
Article Abstract:
The construction of null knockout indole-3-acetic acid (iaaM) mutant strain Erwinia chrysanthemi (Ech138) is presented. Compared with wild-type Ech3937, Ech138 exhibited reduced ability to produce local maceration, but its multiplication in Saintpaulia ionantha was unaffected.
