The desiccation tolerance through a unicellular and chlorophyllous fern spore
(2020-01-08)
La presente tesis, por un lado, establece un protocolo universal para definir la tolerancia a la desecación en tejidos fotosintéticos y posteriormente se centra indagar las características ecofisiológicas que posibilitan ...
Biodiversity patterns in the managed and unmanaged silver fir-beech forests in the western Pyrenees: towards sustainable use.
(2018-04-20)
La explotación forestal está incrementándose en todo el mundo, siendo bien conocido su impacto negativo en la biodiversidad. El concepto de "gestión forestal sostenible" ha irrumpido con fuerza en la silvicultura moderna ...
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 ...
Annual Weedy Species of Erigeron in the Northern Iberian Peninsula: a Review
(Universidad Complutense de Madrid, 2021)
A revision of the alien Erigeron species formerly included in Conyza found in the northern Iberian Peninsula is presented. A close examination of numerous specimens collected by the authors as well as voucher specimens ...
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 ...
Differences in biochemical, gas exchange and hydraulic response to water stress in desiccation tolerant and sensitive fronds of the fern Anemia caffrorum
(Wiley, 2021-08)
Desiccation tolerant plants can survive extreme water loss in their vegetative tissues. The fern Anemia caffrorum produces desiccation tolerant (DT) fronds in the dry season and desiccation sensitive (DS) fronds in the wet ...
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. ...
