Photosynthetic responses of trees in high-elevation forests: comparing evergreen species along an elevation gradient in the Central Andes
(Oxford University Press, 2015)
Plant growth at extremely high elevations is constrained by high daily thermal amplitude, strong solar radiation and water scarcity. These conditions are particularly harsh in the tropics, where the highest elevation ...
Side-Effects of Domestication: Cultivated Legume Seeds Contain Similar Tocopherols and Fatty Acids but Less Carotenoids than Their Wild Counterparts
(Biomed Central, 2014-12-20)
BACKGROUND: Lipophilic antioxidants play dual key roles in edible seeds (i) as preservatives of cell integrity and seed viability by preventing the oxidation of fats, and (ii) as essential nutrients for human and animal ...
Modified atmosphere packaging and dark/light refrigerated storage in green leafy vegetables have impact on nutritional value
(Springer, 2019-01-04)
The consumption of zeaxanthin (Z) through a vegetable-rich diet is recommended to reduce the progression of age-related macular degeneration. Due to Z’s intrinsic dynamic character that results from its participation in ...
Unravelling metabolic mechanisms behind chloroplast desiccation tolerance: chlorophyllous fern spore as a new promising unicellular model
(Elsevier, 2018-11-22)
Fern spores are unicellular structures produced by the sporophyte generation that give rise to the haploid gametophyte. When released from the sporangium, spores are desiccation tolerant (DT) in the royal fern (Osmunda ...
Desiccation Tolerance in Chlorophyllous Fern Spores: Are Ecophysiological Features Related to Environmental Conditions?
(Frontiers Media, 2019-09-20)
Fern spores of most species are desiccation tolerant (DT) and, in some cases, are photosynthetic at maturation, the so-called chlorophyllous spores (CS). The lifespan of CS in the dry state is very variable among species. ...
Life after Harvest: Circadian Regulation in Photosynthetic Pigments of Rocket Leaves during Supermarket Storage Affects the Nutritional Quality
(MDPI, 2019-08)
Vegetables, once harvested and stored on supermarket shelves, continue to perform biochemical adjustments due to their modular nature and their ability to retain physiological autonomy. They can live after being harvested. ...
First evidence of freezing tolerance in a resurrection plant: insights into molecular mobility and zeaxanthin synthesis in the dark
(Wiley, 2018-01-18)
The photoprotective mechanisms of desiccation tolerance and freezing toler- ance and their relation to molecular mobility (cell vitrification) were assessed in a single model: the exceptional subalpine and resurrection ...
Freezing induces an increase in leaf spectral transmittance of forest understorey and alpine forbs
(Springer, 2022)
Evergreen plants growing at high latitudes or high elevations may experience freezing events in their photosynthetic tissues. Freezing events can have physical and physiological effects on the leaves which alter leaf optical ...
Combined dynamics of the 500–600 nm leaf absorption and chlorophyll fluorescence changes in vivo: Evidence for the multifunctional energy quenching role of xanthophylls
(Elsevier, 2021-02-01)
Carotenoids (Cars) regulate the energy flow towards the reaction centres in a versatile way whereby the switch between energy harvesting and dissipation is strongly modulated by the operation of the xanthophyll cycles. ...
More than just lipid balls: quantitative analysis of plastoglobule attributes and their stress‑related responses
(Springer, 2022-03)
[EN] Main conclusion Plastoglobules are ubiquitous under non-stress conditions and their morphology, closely related to their composition, changes differently depending on the specific stress that the plant undergoes. ...
