Ammonia emission from rice leaves in relation to photorespiration and genotyp…

Background and Aims Rice (Oryza sativa) plants lose significant amounts of volatile NH3 from their leaves, but it has not been shown that this is a consequence of photorespiration. Involvement of photorespiration in NH3 emission and the role of glutamine synthetase (GS) on NH3 recycling were investigated using two rice cultivars with different GS activities. Methods NH3 emission (AER), and gro…
