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 ...
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. ...
Can Parietin Transfer Energy Radiatively to Photosynthetic Pigments?
(MDPI, 2018-07)
The main role of lichen anthraquinones is in protection against biotic and abiotic stresses, such as UV radiation. These compounds are frequently deposited as crystals outside the fungal hyphae and most of them emit visible ...
Activation of violaxanthin cycle in darkness is a common response to different abiotic stresses : a case study in Pelvetia canaliculata
(BioMed Central, 2011-12-26)
Background: In the violaxanthin (V) cycle, V is de-epoxidized to zeaxanthin (Z) when strong light or light combined with other stressors lead to an overexcitation of photosystems. However, plants can also suffer stress in ...
Carotenoids and their derivatives: A “Swiss Army knife-like” multifunctional tool for fine-tuning plant-environment interactions
(Elsevier, 2023-03)
Plants have to cope with different biotic and abiotic stresses, such as the attacks of pathogens and herbivores, high irradiance, droughts, salt stress or nutrient deficiencies throughout their lifetime. These environmental ...
Diversity of winter photoinhibitory responses: a case study in co-occurring lichens, mosses, herbs and woody plants from subalpine environments
(Wiley, 2017-02-14)
Winter evergreens living in mountainous areas have to withstand a harsh combination of high light levels and low temperatures in wintertime. In response, evergreens can activate a photoprotective process that consists of ...
Seed Carotenoid and Tocochromanol Composition of Wild Fabaceae Species Is Shaped by Phylogeny and Ecological Factors
(Frontiers Media, 2017-08-24)
Carotenoids distribution and function in seeds have been very scarcely studied, notwithstanding their pivotal roles in plants that include photosynthesis and phytohormone synthesis, pigmentation, membrane stabilization and ...
Non-destructive optical indices to estimate isoprenoids with nutritional value in packed rocket and spinach
(Elsevier, 2024-06)
The quantification of phytochemicals with nutritional benefits relies on accuracy yet time-consuming, expensive and destructive methodologies. In contrast, optical indices widely employed in disciplines such as ecology can ...
