The role of α-tocopherol in plant stress tolerance
- S. Munné-Bosch
- 1 July 2005
Summary Environmental stresses trigger a wide variety of plant responses, ranging from altered gene expression to changes in cellular metabolism and growth. A plethora of plant reactions exist to… Expand
The Function of Tocopherols and Tocotrienols in Plants
Referee: Dr. Kozi Asada, Department of Biotechnology, Faculty of Engineering, Fukuyama University, Gakuencho 1, Fukuyama 729-0292, Japan Tocopherols and tocotrienols, which differ only in the degree… Expand
JUNGBRUNNEN1, a Reactive Oxygen Species–Responsive NAC Transcription Factor, Regulates Longevity in Arabidopsis[W][OA]
Aging in plants is an intricate process that balances vegetative growth with flowering and reproductive success. This work describes the identification of JUNGBRUNNEN1, a NAC transcription factor… Expand
Die and let live: leaf senescence contributes to plant survival under drought stress.
Leaf senescence is a highly regulated physiological process that leads to leaf death and is, as such, the last developmental stage of the leaf. Plant aging and environmental stresses may induce the… Expand
How relevant are flavonoids as antioxidants in plants?
- I. Hernández, L. Alegre, F. Van Breusegem, S. Munné-Bosch
- Biology, Medicine
- Trends in plant science
- 1 March 2009
Flavonoids are a large family of plant secondary metabolites, principally recognized for their health-promoting properties in human diets. Most flavonoids outperform well-known antioxidants, such as… Expand
Changes in carotenoids, tocopherols and diterpenes during drought and recovery, and the biological significance of chlorophyll loss in Rosmarinus officinalis plants
Abstract. Two-year-old rosemary (Rosmarinus officinalis L.) plants were subjected to severe stress by exposure to prolonged drought during a Mediterranean summer. Severely stressed plants recovered… Expand
Transcription Factor ATAF1 in Arabidopsis Promotes Senescence by Direct Regulation of Key Chloroplast Maintenance and Senescence Transcriptional Cascades1[OPEN]
A transcription factor from Arabidopsis antagonistically controls regulators of senescence and photosynthesis. Senescence represents a fundamental process of late leaf development. Transcription… Expand
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 of… Expand
Tocochromanol functions in plants: antioxidation and beyond.
Tocopherols and tocotrienols, collectively known as tocochromanols, are lipid-soluble molecules that belong to the group of vitamin E compounds and are essential in the human diet. Not surprisingly,… Expand
The Impact of Global Change Factors on Redox Signaling Underpinning Stress Tolerance1[W]
Reduction/oxidation (redox) metabolism and associated signaling are key components of cross tolerance to biotic and abiotic stresses in plants. Climate change factors such as predicted increases in… Expand
