Abstract excerpt
A Saccharomyces cerevisiae mutant (zrt1Delta) lacking the ZRT1 gene, which encodes a high-affinity Zn(2+) transporter, scarcely thrived in a low-pH, low-phosphate medium because of Zn(2+) deficiency. Supplementation of the medium with Al(3+) restored growth to a level comparable to that of a wild-type strain. A metal determination study clearly demonstrated that Al(3+) induced the incorporation of Zn(2+) into...
