Photosynthesis inhibitors … WebThe recovery of photosynthesis was also more rapid in MSO-treated leaf discs although ammonia levels were more than threefold higher. Photosynthesis in leaf discs treated with azaserine was inhibited more than controls when transferred to 21% O(2) and recovered less than controls when returned to 2% O(2) although NH(4) (+) levels were not ...
WebThe toxic effects of ammonia on many photosynthetic organisms have long been known. Ammonium hydroxide inhibits the enzyme NADP dehydrogenase, which subsequently prevents NADP + from turning into NADPH at the end of the electron transport chain. WebPlants acquire these forms of “combined” nitrogen by: 1) the addition of ammonia and/or nitrate fertilizer (from the Haber-Bosch process) or manure to soil, 2) the release of these compounds...
