expression in Saccharomyces cerevisiae confers tolerance to aluminium to the cells	Arabidopsis thaliana
gene S581, DNA and amino acid sequence determination and analysis, expression in Saccharomyces cerevisiae and constitutively in Arabidopsis thaliana, under control of the CaMV35S promoter, confers tolerance to aluminium and gadolinium, Gd3+, but not to lanthanum, La3+, or manganese, Mn2+, to cells and seedlings, respectively, the transgenic expression leads to the accumulation of 8(Z/E)-C18-phytosphingenine and 8(Z/E)-C20-phytopshingenine in yeast and to the accumulation of 8(Z/E)-C18-phytosphingenine in the leaves and roots of Arabidopsis plants, overview	Stylosanthes hamata
