Scheme 1.
Diagram of the experimental setup. Water deficit (D) started at the beginning and lasted until the sixth day of the experiment, followed by a six day re-watering period (R), until the 12th day of the experiment. Arrows indicate harvesting points: on the sixth day (D and CD, respective control) and the 12th day of the experiment (R and CR, respective control. SWC (soil water content) was ~38% (blue line) in well-watered plants (control and re-watered plants) and reached (~12%, pink line) during the 6 day water deficit period (D). All the analyses were performed on the fourth fully developed tomato leaf (orange circle).
