dc.description.abstractEn<div><p>Photosynthesis-related parameters (A n , g s , g m and J flu ) and K leaf were strongly coordinated during dehydration. Stomatal closure and photosynthesis cessation occurred prior to the onset of embolism. Chl was dismantled at the last stage (F v /F m decrease), after most vessels showed complete embolism.</p><p>• B. purpurea shows a 'water-conservative' or isohydric behavior, which may be associated with delaying dehydration to prepare the molecular changes required in the desiccated state. These results differ from other resurrection species, where it has been suggested a strategy related to maximizing carbon gain during dehydration (Sherwin et al 1988). Stomata act as safety valves to protect the vascular system from cavitation (Creek et al 2020), even in a plant able to fully recover after complete embolism.</p><p>• Rehydration (leaf Ψ ~0 MPa) occurred rapidly in the mesophyll (12-24 h), whereas complete xylem refilling likely occurred at later stages (&gt;24 h) after rewatering.</p><p>Photosynthesis recovery was associated with resuming hydraulic function but also with re-synthesis of Chl and the photochemical apparatus.</p><p>Hydraulic and photosynthesis responses to desiccation and recovery in the resurrection plant Barbacenia purpurea</p></div>
