Rapid plant rehydration initiates permanent and adverse changes in the photosynthetic apparatus of triticale

Tomasz Hura; Katarzyna Hura; Agnieszka Ostrowska; et al. Plant and Soil 2015. doi:10.1007/s11104-015-2607-1

Other claims from this paper (9)

Intervention effect Rehydration further increased hydrogen peroxide in the cultivar that did not fully recover.
Intervention effect Rehydration inhibited photosynthetic apparatus activity compared with drought in that cultivar.
Observation On day 42 of rehydration, flag leaf photosynthetic activity was reduced.
Intervention effect Rapid rehydration lowered total peroxidase activity in its first week.
Intervention effect Rapid rehydration lowered catalase activity in its first week.
Observation Gradual restoration of leaf water content compensated increased hydrogen peroxide.
Observation Gradual leaf water restoration prevented further decline in photosynthetic apparatus activity.
Mechanism Rapid rehydration intensified physiological processes associated with reactive oxygen species overproduction.
Mechanism The authors suggest electron leakage from an overloaded electron transport chain causes hydrogen peroxide overproduction.
