When the sun never sets: daily changes in pigment composition in three subarctic woody plants during the summer solstice

Fernández Marín, Beatriz; Atherton, Jon; Olascoaga, Beñat; Kolari, Pasi; Porcar Castell, Albert; García Plazaola, José Ignacio (Springer, 2018-02-02)

Composition and content of photosynthetic pigments is finely tuned by plants according to a subtle equilibrium between the absorbed and used energy by the photosynthetic apparatus. Subarctic and Arctic plants are subjected ...

Side-Effects of Domestication: Cultivated Legume Seeds Contain Similar Tocopherols and Fatty Acids but Less Carotenoids than Their Wild Counterparts

Fernández Marín, Beatriz; Milla, Rubén; Martín Robles, Nieves; Arc, Erwann; Kranner, Ilse; Becerril Soto, José María; García Plazaola, José Ignacio (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 ...

A field portable method for the semi-quantitative estimation of dehydration tolerance of photosynthetic tissues across distantly related land plants.

López Pozo, Marina; Flexas, Jaume; Gulias, Javier; Nadal, Miquel; Perera-Castro, Alicia; Clemente-Moreno, Maria Jesus; Gago, Jorge; Nuñez-Oliveira, Encarnación; Martinez-Abaigar, Javier; Hernández Hernández, Antonio; Artetxe Aspiunza, Unai; Bentley, Joanne; Farrant, Jill; Verhoeven, Amy; García Plazaola, José Ignacio; Fernández Marín, Beatriz (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 ...

Unravelling metabolic mechanisms behind chloroplast desiccation tolerance: chlorophyllous fern spore as a new promising unicellular model

López Pozo, Marina; Gasulla, F; García Plazaola, José Ignacio; Fernández Marín, Beatriz (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 ...

Rapid colour changes in Euglena sanguinea (Euglenophyceae) caused by internal lipid globule migration

Laza Martínez, Aitor; Fernández Marín, Beatriz; García Plazaola, José Ignacio (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 ...
