Abstract
Eleven aluminum stress-induced genes derived from plants (wheat, Arabidopsis and tobacco) were introduced into Saccharomyces cerevisiae to test if expression of these genes confers A1 tolerance. A1 sensitivity tests showed that expression of two genes, either an Arabidopsis gene for blue copper binding protein (BCB), or a tobacco gene for the GDP dissociation inhibitor (NtGDI1), conferred A1 tolerance. Determinations of total content and localization of A1 ions in these transformants suggested that the BCB gene product functions in restricting A1 uptake, while expression of the NtGDI1 gene promotes release of A1 ions after uptake.
