| Abstract: | Copper-containing bactericides have been used to control bacterial canker of kiwifruit, caused by Pseudomonas syringae pv. actinidiae. However, the efficacy of copper has been reduced by the occurrence of copper-resistant strains. Analysis of the DNA sequence of a cluster region containing the copper-resistance genes from P. syringae pv. actinidiae suggested the presence of three possible different systems for copper resistance: copper-trapping, copper-efflux and copper-transport systems. Transposon insertional inactivation analysis indicated that the copper-trapping system was essential for copper resistance. |
