However, more studies are needed to identify the role that N plays in the regulation of stomatal movement. Generally, plants reduce water loss by partial closing of stomata under water stress conditions. Asp is linked to malate via oxaloacetate, by malate dehydrogenase and aminotransferase activities, which play key roles in redox shuttles during phototorespiration Leegood et al. It is postulated that the unchanged gm under water stress could be due to the fact that short-term WD treatment is not long enough to change the leaf anatomical structure. As high concentration of ammonium is toxic to plant cell, the high capacity to assimilate ammonium could be an important factor in alleviating the consequence of stress Hoai et al. Besides, the trade-off between growth and stress defense could also be responsible for the resistance of photosynthesis to water stress Karasov et al.
