Influence of methionine sulfoximine on the photosynthesis of isolated chloroplasts.
Methionine sulfoximine provided at a concentration which inhibits photosynthesis in intact leaves (10 mM) had no significant influence on the rate of photosynthesis of isolated pea leaf chloroplasts. In contrast, ammonium, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, and D,L-glyceraldehyde all strongly inhibited the photosynthesis of isolated chloroplasts. We conclude that low concentrations of methionine sulfoximine (up to 10 mM) have no direct effect on the photosynthetic process.
