Effects on GSH synthesis in Chinese cabbage when the culturing solution is supplemented with ammonium sulfate or the constituent amino acids for glutathione
Abstract:We examined the effects of the constituent amino acids for glutathione (GSH) -. glutamate (Glu), cysteine (Cys), and glycine (Gly) --on GSH synthesis in Chinese cabbage seedlings. Glu, Cys, and Gly were applied simultaneously (100 mg L 1) to the culture solution for 2 d. When compared with the control, GSH concentrations were increased by 2.1-fold (640.4 nmol gl F~/V) and 1.5-fold (416.4 nmol g-1 FW) in the first leaf and the roots, respectively. Of all the free amino acids, the non-essentials, including Glu, … Show more
