A field portable method for the semi-quantitative estimation of dehydration tolerance of photosynthetic tissues across distantly related land plants.
(2018-12-04)
Desiccation tolerant (DT) plants withstand complete cellular dehydration (reaching relative
water contents below 30% in their photosynthetic tissues), while desiccation sensitive (DS)
plants exhibit different degrees of ...
Opening Pandora's box: cause and impact of errors on plant pigment studies
(Frontiers Research Foundation, 2015-03-12)
Rapid colour changes in Euglena sanguinea (Euglenophyceae) caused by internal lipid globule migration
(Taylor & Francis, 2018-11-23)
The accumulation of red pigments under chronic stress is a response observed in most
groups of oxygenic photoautotrophs. It is thought that the red pigments in the cell shield
the chlorophyll located underneath from the ...
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 ...
Protective Strategies of Haberlea rhodopensis for Acquisition of Freezing Tolerance: Interaction between Dehydration and Low Temperature
(MDPI, 2022-11-30)
Resurrection plants are able to deal with complete dehydration of their leaves and then recover normal metabolic activity after rehydration. Only a few resurrection species are exposed to freezing temperatures in their ...
Photoprotective Strategies of Mediterranean Plants in Relation to Morphological Traits and Natural Environmental Pressure: A Meta-Analytical Approach
(Frontiers Media, 2017-06-19)
Despite being a small geographic extension, Mediterranean Basin is characterized by an exceptional plant biodiversity. Adaptive responses of this biocoenosis are delineated by an unusual temporal dissociation along the ...
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 ...
Ageing kinetics of fern chlorophyllous spores during dry storage is determined by its antioxidant potential and likely induced by photosynthetic machinery
(Elsevier, 2023-12)
Ageing in dry chlorophyllous propagules is leaded by photooxidation through the photosynthetic machinery, but why species differ in longevity and the ageing mechanisms of when light and oxygen are absent are unknown. We ...
Constrained trait variation by water availability modulates radial growth in evergreen and deciduous Mediterranean oaks
(Elsevier, 2024-03)
Spatial and temporal variation in functional traits allows trees to adjust to shifting environmental conditions such as water stress. However, the change of traits, both mean and variances, along water availability gradients ...
Acquisition of Desiccation Tolerance Unveiled: Polar Lipid Profiles of Streptophyte Algae Offer Insights
(Wiley, 2023-11)
Terrestrialization by photosynthetic eukaryotes took place in the two branches of green microalgae: Chlorophyta and Charophyta. Within the latter, the paraphyletic streptophytic algae divide into two clades. These are named ...
