Accumulation of Copper and Other Metals by Copper

Copper resistant strains ofdomonas syringae carrying the cop operon produce periplasmic copper binding proteins, and this sequestration outside the cytoplasm has been proposed as a resistance mechanism. In this study, strain PS61 of P. syringae carrying the cloned cop operon accumulated more total cellular copper than without the operon.

Complexation and Toxicity of Copper in Higher Plants. I

The amphibious water plant Crassula helmsii is an invasive copper Cu tolerant neophyte in Europe. It now turned out to accumulate Cu up to more than 9,000 ppm in its shoots at 10 μ m =0.6 ppm Cu2+ in the nutrient solution, indicating that it is a Cu hyperaccumulator. We investigated uptake, binding environment, and toxicity of Cu in this plant under emerged and submerged conditions.
