Heavy metals and thiol pool in three strains of Tetracladium marchalianum
Growth of three strains of Tetracladium marchalianum was inhibited by Cd-, and, to a lesser extent, by Cu-and Zn-chloride. In the presence of 50 μM Cd(II), all strains increased total thiol and glutathione produc...

First step towards a quantitative model describing Czc-mediated heavy metal resistance in Ralstonia metallidurans
Quantitative models were derived to explain heavy metal resistance in Ralstonia metallidurans. A ΔczcA deletion of the gene for the central component of the Co2+/Zn2+/Cd2+ efflux system CzcCBA combined with the e...

Excessive iron accumulation in the pea mutants dgl and brz: subcellular localization of iron and ferritin
The pea (Pisum sativum L.) mutants dgl and brz are defective in the regulation of iron uptake. Enhanced proton extrusion and constitutively high Fe(III) reductase activities in the roots lead to an accumulation ...

Early responses to gibberellic acid in a dwarf maize mutant (Zea mays L. d 1)
Early effects of gibberellic acid (GA3) (1–4 h treatment) on the ion ratios in a dwarf maize mutant (Zea mays L. d 1) showing normal growth after hormone treatment, have been investigated by electron microprobe a...
