Abstract excerpt
As an approach to understand the regulation of methionine (Met) metabolism, Arabidopsis Met over-accumulating mutants were isolated based on their resistance to selection by ethionine. One mutant, mto3, accumulated remarkably high levels of free Met - more than 200-fold that observed for wild type - yet showed little or no difference in the concentrations of other protein amino-acids, such as aspartate, threonine...
