• Methionine sulfoximine caused ammonia accumulation and photosynthetic rate inhibition in leaf discs from two C_4 species, Zea mays L. cv. F. M. Cross (Hybrid) and Sorghum bicolor L. Moench cv. NC-70X, as well as one C_3 plant species, Datura stramonium L. cv. stramonium. Similar results were obtained earlier with the C_3 species Spinacia oleracea L. The effect occurred in the absence of inorganic nitrogen reduction and was light dependent. Ammonia accumulation rates were similar in all four species examined. The results support a role for glutamine synthetase in leaf ammonia recycling in both C_4 and C_3 leaves.
