The methionine (Met) cycle contributes to sulfur metabolism through the conversion of methylthioadenosine (MTA) to Met at the expense of ATP. MTA is released as a by-product of ethylene synthesis from S-adenosylmethionine (AdoMet). Disruption of the Met cycle in the Arabidopsis mtk mutant resulted in an imbalance of AdoMet homeostasis at sulfur-limiting conditions, irrespective of the sulfur source supplied to the plants. At a low concentration of 100 mum sulfate, the mtk mutant had reduced… CONTINUE READING
