- Intervention effect Water withholding lowered RWC to about 50%.
- Intervention effect Water potential dropped to -12 bars.
- Intervention effect ABA rose sharply at 75% RWC.
- Intervention effect Stomatal closure limited CO2 uptake.
- Intervention effect Organic acid fluctuations were dampened in CAM idling.
- Intervention effect Chlorophyll, protein and Rubisco activity were unchanged relative to watered plants.
- Intervention effect PEPc mRNA, activity, and protein rose under stress.
- Intervention effect Apparent Km(PEP) fell under stress.
- Observation Km(PEP) changes were not an assay artifact.
- Intervention effect Metabolism quickly returned to the well watered CAM state after rewatering.
