Rodríguez-Calcerrada, Jesús; Rodrigues, Ana M; Perdiguero, Pedro; António, Carla; Atkin, Owen; Li, Meng; Collada, Carmen; Gil, Luis


Drought-induced reduction of leaf gas exchange entails a complex regulation of the plant leaf metabolism. We used a combined molecular and physiological approach to understand leaf photosynthetic and respiratory responses of 2-year-old Quercus ilex seedlings to drought. Mild drought stress resulted in glucose accumulation while net photosynthetic CO2 uptake (Pn) remained unchanged, suggesting a role of glucose in stress signaling and/or osmoregulation. Simple sugars and sugar alcohols increased...[Show more]
