The significance of total glutathione content was investigated in two alpine plant species with highly differing antioxidative scavenging capacity. Leaves of Soldanella alpina and Ranunculus glacialis incubated for 48 h in the presence of buthionine-sulfoximine had 50% lower glutathione contents when compared with leaves incubated in water. The low leaf glutathione content was not compensated for by activation of other components involved in antioxidative protection or electron consumption… 

Dynamic acclimation to sunlight in an alpine plant, Soldanella alpina L.

In the French Alps, Soldanella alpina (S. alpina) grow under shade and sun conditions during the vegetation period. This species was investigated as a model for the dynamic acclimation of shade

Photosynthesis and Photosynthetic Electron Flow in the Alpine Evergreen Species Quercus guyavifolia in Winter

Night air temperature was an important determinant of stomatal/mesophyll conductance and photosynthesis when photosynthesis is inhibited following freezing night temperatures, which support the role of photorespiration and alternative electron flow in photoportection for alpine plants under low temperatures.

Involvement of chlororespiration in chilling stress in the tropical species Spathiphyllum wallisii.

The results indicated that the contribution of chlororespiration to regulating photosynthetic electron flow is not relevant when the whole plant is chilled under high light, and that another pathway, such as cyclic electron flow involving PGR5 polypeptide, may be more important.

Plastid terminal oxidase (PTOX) has the potential to act as a safety valve for excess excitation energy in the alpine plant species Ranunculus glacialis L.

The results suggest that PTOX can act as a safety valve in R. glacialis leaves under conditions where incident photon flux density (PFD) exceeds the growth PFD and under conditionsWhere the plastoquinone pool is highly reduced.

The Effects of Cold Stress on Photosynthesis in Hibiscus Plants

The present work studies the effects of cold on photosynthesis, as well as the involvement in the chilling stress of chlororespiratory enzymes and ferredoxin-mediated cyclic electron flow, in

Application of heat stress in situ demonstrates a protective role of irradiation on photosynthetic performance in alpine plants

This study demonstrates that, in the European Alps, heat waves can temporarily have a negative impact on photosynthesis and, importantly, that results obtained from experiments performed in darkness and/or on detached plant material may not reliably predict the impact of heat stress under field conditions.

High root temperature affects the tolerance to high light intensity in Spathiphyllum plants.



Protection from Paraquat‐Mediated Photo‐Oxidative Stress by Glutathione in Poplar (Populus tremula×P. alba) Plants

Feeding experiments with glutathione and its metabolic precursor γ-glutamylcysteine (EC) plus gly showed that glutathion can provide protection from paraquat-mediated photo-oxidative stress; but at least ca.

Reversibility of cold- and light-stress tolerance and accompanying changes of metabolite and antioxidant levels in the two high mountain plant species Soldanella alpina and Ranunculus glacialis.

It is shown that acclimation is reversible in R. glacialis leaves, but constitutive or long-lasting in S. alpina leaves, and that malate contents declined significantly in de-acclimated leaves, suggesting a possible involvement of malate, or malate metabolism, in light-stress tolerance.

High Temperature Effects on Light Sensitivity in the Two High Mountain Plant Species Soldanella alpina (L.) and Rannunculus glacialis (L.)

Results indicate that carbon assimilation was inhibited and that membranes were affected, and the increased susceptibility of R. glacialis leaves to light-induced photoinhibition after growth at mode rate temperature and the inability to repair heat-induced damage might limit the distribution of the plant to lower altitudes in the Alps.

Significance of antioxidants and electron sinks for the cold‐hardening‐induced resistance of winter rye leaves to photo‐oxidative stress

The resistance of CHL to low temperature-induced photo-inactivation of PSII and catalase required repair at low temperature and active carbon assimilation but was only little affected when photorespiration was suppressed by phosphinothricin.

Divergent strategies of photoprotection in high-mountain plants

Application of phosphinothricin, which interferes with photorespiration by inhibition of glutamine synthetase, caused a striking reduction of electron transport through photosystem II and induced marked photoinhibition at both ambient and low temperature in leaves of R. glacialis, which appeared to provide a strong electron sink and a most essential means of photoprotection, even at low temperature.

Role of glutathione in adaptation and signalling during chilling and cold acclimation in plants.

The finding that several defence genes have antioxidant responsive elements or GSSG binding sites in their regulatory regions supports the idea that redox signalling is involved in regulating gene expression in response to low temperature.

Inhibition of glutathione synthesis reduces chilling tolerance in maize

The results show that BSO did not reduce chilling tolerance of the maize genotype analyzed by inhibiting abscisic acid accumulation but by establishing a low level of GSH, which also induced a decrease in GR activity.

The effect of heat on photosynthesis, dark respiration and cellular ultrastructure of the arctic-alpine psychrophyte Ranunculus glacialis

An unusually wide temperature range from the start of reversible photosynthetic inhibition to incipient necrosis indicated a pronounced heat sensitivity, particularly in cellular functions, of this arctic-alpine species.

Resistance of cold‐hardened winter rye leaves (Secale cereale L.) to photo‐oxidative stress

Catalase and photosystem II (PSII) were strongly inactivated during exposure to 4 °C and moderate light in 22 °C-grown non-hardened leaves (NHL) of winter rye (Secale cereale L.), but highly
