Scheme reflecting the role of folate metabolism in redox homeostasis in plants. The folate pathway possibly contributes to production of NADPH that is used to detoxify ROS. Additionally, 5-CH3-THF takes part in the conversion of Hcy into Met, thereby preventing ROS production. Green areas represent pathways contributing to NADPH production, blue areas show pathways consuming NADPH, biosynthetic processes and ROS removal. THF, tetrahydrofolate; 5-CH3-THF, 5-methyltetrahydrofolate; 5,10-CH2-THF, 5,10-methylenetetrahydrofolate; 10-CHO-THF, 10-formyltetrahydrofolate.
