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. ...
Non-invasive diagnosis of viability in seeds and lichens by infrared thermography under controlled environmental conditions
(BMC, 2019-12)
Background: Non-invasive procedures for the diagnosis of viability of plant or fungal tissues would be valuable for scientific, industrial and biomonitoring purposes. Previous studies showed that infrared thermography (IRT) ...
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 ...
Xanthophyll cycles in the juniper haircap moss (Polytrichum juniperinum) and Antarctic hair grass (Deschampsia antarctica) on Livingston Island (South Shetland Islands, Maritime Antarctica)
(Springer, 2022)
The summer climate in Maritime Antarctica is characterised by high humidity and cloudiness with slightly above zero temperatures. Under such conditions, photosynthetic activity is temperature-limited and plant communities ...
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 ...
On the recalcitrant use of Arnon’s method for chlorophyll determination
(New Phytologist Trust, 2017-11-28)
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 ...
