摘要：

Maize plants fed with PPT (a glutamine synthetase inhibitor) accumulate ammonia. Approximately 50% of the ammonia accumulated seems to come from the photorespiratory pathway, while the non-photorespiratory ammonia is derived from nitrate reductase activity. The ammonia accumulated, however, is not sufficient to increase GDH activity. We also carried out a comparative study of the effect of PPT and AOA on photosynthesis. Both compounds inhibit the photorespiratory pathway, causing glycolate accumulation and diminishing photosynthesis.
