Rapid and sensitive hormonal profiling of complex plant samples by liquid chromatography coupled to electrospray ionization tandem mass spectrometry
BackgroundPlant hormones play a pivotal role in several physiological processes during a plant's life cycle, from germination to senescence, and the determination of endogenous concentrations ofExpand

Photo-oxidative stress in emerging and senescing leaves: a mirror image?
The life cycle of a leaf can be characterized as consisting of different stages: from primordial leaf initiation in the shoot apical meristem (SAM) to leaf senescence. Leaf development, from earlyExpand

α-Tocopherol may influence cellular signaling by modulating jasmonic acid levels in plants
Most studies on the function of tocopherols in plants have focused on their photo-protective and antioxidant properties, and it has been recently suggested, though not yet demonstrated, that they mayExpand

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

Phenolic diterpene and α-tocopherol contents in leaf extracts of 60 Salvia species
BACKGROUND: Carnosic acid and carnosol, the two major phenolic diterpenes present in rosemary and sage extracts, have received attention in food science and biomedicine because of their potentExpand

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

Ethylene Response Factors: A Key Regulatory Hub in Hormone and Stress Signaling1
Ethylene Response Factors are transcription factors that act as a key regulatory hub in plant response to abiotic stresses, integrating ethylene, ABA, jasmonate, and redox signaling. Ethylene isExpand

Enhanced alpha-tocopherol quinone levels and xanthophyll cycle de-epoxidation in rosemary plants exposed to water deficit during a Mediterranean winter.
Photosynthesis operates in a constantly shifting balance between efficient capture of solar energy and its rapid dissipation when captured in excess. In an attempt to better understand the role ofExpand

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

Kinetin applications alleviate salt stress and improve the antioxidant composition of leaf extracts in Salvia officinalis.
A pot experiment was carried out under glasshouse conditions with common sage (Salvia officinalis L.) to investigate the interactive effects of salt stress and kinetin on growth attributes and theExpand
