Flavonoids have long been recognized as playing multiple roles in the responses of higher plants to a wide range environmental constraints (Winkel-Shirley, 2002; Roberts & Paul, 2006), and early proposed developmental regulators (Stafford, 1991). Over last three decades, ozone depletion has become major problem, particular role flavonoids screening short-wavelength solar UV-B radiation (over 280–315 nm waveband) strongly emphasized (Rozema et al., 1997; Burchard 2000). It is now well...
• The differential accumulation of various polyphenols, particularly flavonoids and hydroxycinnamates, was studied in leaves Ligustrum vulgare exposed to increasing sunlight under well watered or drought-stress conditions. Light- drought-induced changes leaf polyphenol concentrations were normalized the CO2 assimilation rate. functional roles hydroxycinnamates analysed through tissue localization using multispectral fluorescence microimaging, efficiencies scavenge superoxide radicals (O2−)...
• The hypothesis was tested that flavonoids may scavenge singlet oxygen (1O2) in mesophyll cells of Phillyrea latifolia exposed to excess-light stress. In cross-sections taken from leaves developed at 10% (shade) or 100% (sun) solar irradiance, we evaluated the excess photosynthetically active radiation (PAR)-induced accumulation 1O2 by imaging fluorescence quenching specific probe...
Flavonoids have the potential to serve as antioxidants in addition their function of UV screening photoprotective mechanisms. However, flavonoids long been reported accumulate mostly epidermal cells and surface organs response high sunlight. Therefore, how leaf actually carry out antioxidant functions is still a matter debate. Here, distribution with effective properties, i.e. orthodihydroxy B-ring-substituted quercetin luteolin glycosides, was investigated mesophyll Ligustrum vulgare leaves...
Abstract. The CEFLES2 campaign during the Carbo Europe Regional Experiment Strategy was designed to provide simultaneous airborne measurements of solar induced fluorescence and CO2 fluxes. It combined with extensive ground-based quantification leaf- canopy-level processes in support ESA's Candidate Earth Explorer Mission "Fluorescence Explorer" (FLEX). aim this test if signal detected from an platform can be used improve estimates plant mediated exchange on mesoscale. Canopy quantified four...
• The role of flavonoids in mechanisms acclimation to high solar radiation was analysed Ligustrum vulgare and Phillyrea latifolia, two Mediterranean shrubs that have the same flavonoid composition but differ strikingly their leaf morpho-anatomical traits. In plants exposed 12 or 100% radiation, measurements were made for surface morphology anatomy; optical properties, photosynthetic pigments, photosystem II efficiency; antioxidant enzymes, lipid peroxidation phenylalanine ammonia lyase;...
Isoprene strengthens thylakoid membranes and scavenges stress-induced oxidative species. The idea that isoprene production might also influence isoprenoid phenylpropanoid pathways under stress conditions was tested. We used transgenic tobacco to compare physiological biochemical traits of isoprene-emitting (IE) non-emitting (NE) plants exposed severe drought subsequent re-watering. Photosynthesis less affected by in IE than NE plants, higher rates were observed recovering from drought....
Anthocyanic morphs are generally less efficient in terms of carbon gain, but, turn, more photoprotected than anthocyanin-less ones. To date, mature leaves different or at developmental stages within the same species have been compared, whereas there is a lack knowledge regarding development red vs green leaves. Leaves (1-, 7-, and 13-week-old) red- (RLP) green-leafed (GLP) Prunus photosynthetic rate, metabolism photoprotective mechanisms were compared to test whether anthocyanin-equipped...
There is a large potential in Europe for valorization the vegetable food supply chain. For example, there occasionally overproduction of tomatoes fresh consumption, and fraction production unsuited consumption sale (unacceptable color, shape, maturity, lesions, etc.). In countries where facilities infrastructure tomato processing lacking, these are normally destroyed, used as landfilling or animal feed, represent an economic loss producers negative environmental impact. Likewise, also...
The effect of leaf temperature (T), between 23 and 4°C, on the chlorophyll (Chl) fluorescence spectral shape was investigated under moderate (200 μE m−2 s−1) low (30–35 light intensities in Phaseolus vulgaris Pisum sativum. With decreasing temperature, an increase yield at both 685 735 nm observed. A marked change occurred longer emission band resulting a decrease Chl ratio, F685/F735, with reducing T. Our analysis suggests that this is due to temperature-induced state 1–state 2 transition...
