The Effect of Bialaphos on Ammonium-Assimilation and Photosynthesis II. Effect on Photosynthesis and Photorespiration
Ammonium-Accumulation. Bialaphos, Phosphinothricin, Photorespiration, Photosynthesis The application of bialaphos (phosphinothricyl-alanyl-alanine) effects a quick photosynthesis inhibition under atmospheric conditions (400 ppm C 0 2, 21% 0 2). However, under conditions (1000 ppm C 0 2, 2% 0 2) under which photorespiration cannot occur there is no photosynthesis inhibition. In the previous inve...
متن کاملThe Effect of Phosphinothricin (Glufosinate) on Photosynthesis II. The Causes of Inhibition of Photosynthesis
It was shown in the previous study that phosphinothricin (glufosinate) causes an accumulation of ammonia and inhibition o f photosynthesis. The extent to which there is a connection between these two processes is now investigated in the present study. First of all, the role of N H 3 per se in the impairment of photosynthesis was to be clarified. For this purpose, the inhibition of photosyn the...
متن کاملPhotosystem II: the reaction center of oxygenic photosynthesis.
Photosystem II (PSII) uses light energy to split water into chemical products that power the planet. The stripped protons contribute to a membrane electrochemical potential before combining with the stripped electrons to make chemical bonds and releasing O2 for powering respiratory metabolisms. In this review, we provide an overview of the kinetics and thermodynamics of water oxidation that hig...
متن کاملPhotosynthesis in Rhodospirillum rubrum. II. Photoheterotrophic carbon dioxide fixation.
The contribution of the reductive pentose phosphate cycle to the photometabolism of carbon dioxide and to carbon metabolism in Rhodospirillum rubrum grown photoheterotrophically with l-malate as the carbon source is nil, unlike autotrophically grown R. rubrum. Glycolic acid appears to be the first stable product of CO(2) fixation in R. rubrum cultured photoheterotrophically on l-malate. The res...
متن کاملPhotosystem II: the water-splitting enzyme of photosynthesis.
The oxygen in our atmosphere is derived and maintained by the water-splitting process of photosynthesis. The enzyme that facilitates this reaction and therefore underpins virtually all life on our planet is known as photosystem II (PSII), a multisubunit enzyme embedded in the lipid environment of the thylakoid membranes of plants, algae, and cyanobacteria. During the past 10 years, crystal stru...
