Early effects of salt stress on the physiological and oxidative status of Cakile maritima (halophyte) and Arabidopsis thaliana (glycophyte).
Early changes in physiological and oxidative status induced by salt stress were monitored in two Brassicaceae plants differing in their tolerance to salinity, Cakile maritima (halophyte) andExpand

A comparative study of the early osmotic, ionic, redox and hormonal signaling response in leaves and roots of two halophytes and a glycophyte to salinity
Salt stress is one of the most important abiotic stress factors affecting plant growth and productivity in natural ecosystems. In this study, we aimed at determining possible differences between saltExpand

Perennially young: seed production and quality in controlled and natural populations of Cistus albidus reveal compensatory mechanisms that prevent senescence in terms of seed yield and viability
This study evaluated if plant ageing can influence the production and composition of seeds in controlled and natural populations of Cistus albidus. Results indicate that reduced plant size in naturalExpand

Increased sensitivity to salt stress in tocopherol-deficient Arabidopsis mutants growing in a hydroponic system
Recent studies suggest that tocopherols could play physiological roles in salt tolerance but the mechanisms are still unknown. In this study, we analyzed changes in growth, mineral and oxidativeExpand

Accumulation of γ- rather than α-tocopherol alters ethylene signaling gene expression in the vte4 mutant of Arabidopsis thaliana.
Tocopherols are antioxidants found in chloroplasts of leaves, and it is a matter of current debate whether or not they can affect signaling and gene expression in plant cells. For insight into theExpand

Physiological and molecular responses of the isoprenoid biosynthetic pathway in a drought-resistant Mediterranean shrub, Cistus creticus exposed to water deficit.
The goal of the present research was to obtain new insights into the mechanisms underlying drought stress resistance in plants. Specifically, we evaluated changes in the expression of genes encodingExpand

Diurnal changes in photosystem II photochemistry, photoprotective compounds and stress-related phytohormones in the CAM plant, Aptenia cordifolia
Abstract Acclimation of photosynthetic light reactions to daily changes in solar radiation requires adjustments in photosystem II photochemistry and may be affected by environmental stresses, such asExpand

Glutathione and transpiration as key factors conditioning oxidative stress in Arabidopsis thaliana exposed to uranium
Although oxidative stress has been previously described in plants exposed to uranium (U), some uncertainty remains about the role of glutathione and tocopherol availability in the differentExpand

Vitamin E analyses in seeds reveal a dominant presence of tocotrienols over tocopherols in the Arecaceae family.
Tocopherols are thought to prevent oxidative damage during seed quiescence and dormancy in all angiosperms. However, several monocot species accumulate tocotrienols in seeds and their role remainsExpand

Antioxidant Defenses Against Drought Stress
Plants possess a battery of structural, physiological, biochemical, and molecular mechanisms to withstand drought periods. During drought, stomatal limitation of photosynthesis, overreduction of theExpand
