Abstract excerpt

Methionine is a key sulfur-containing amino acid and the precursor of S-adenosylmethionine, the universal methyl donor for DNA and histone methylation. While reduced S-adenosylmethionine availability is known to cause DNA hypomethylation, the effects of elevated methionine/S-adenosylmethionine remain poorly understood. Here, we addressed the effect of elevated methionine using the mto1 mutant of Arabidopsis...
