A multi-tool approach to assess microalgal diversity in lichens. isolation, Sanger sequencing, HTS and ultrastructural correlations

Molins, Arantxa; Moya, P.; García-Breijo, Francisco-José; Reig-Armiñana, José; Barreno, Eva (Cambridge University Press, 2018)

[EN] Lichen thalli represent the most conspicuous examples of fungal-algal interactions. Studies that describe phycobiont diversity within entire thalli are based mainly on Sanger sequencing. In some lichen species, this ...
Coordinated ultrastructural and phylogenomic analyses shed light on the hidden phycobiont diversity of Trebouxia microalgae in Ramalina fraxinea

Català, Santiago; Campo, Eva del; Barreno, Eva; García-Breijo, Francisco-José; Reig Armiñana, José; Casano, Leonardo (Elsevier, 2016-01)

[EN] The precise boundary delineations between taxa in symbiotic associations are very important for evolutionary and ecophysiological studies. Growing evidence indicates that in many cases, the use of either morphological ...
Inhibition of NO Biosynthetic Activities during Rehydration of Ramalina farinacea Lichen Thalli Provokes Increases in Lipid Peroxidation

Expósito, Joana R.; Martín San Román, Sara; Barreno, Eva; Reig-Armiñana, José; García-Breijo, Francisco-José; Catalá, Myriam (MDPI, 2019-07)

[EN] Lichens are poikilohydrous symbiotic associations between a fungus, photosynthetic partners, and bacteria. They are tolerant to repeated desiccation/rehydration cycles and adapted to anhydrobiosis. Nitric oxide (NO) ...
Molecular and Morphological Diversity of Trebouxia Microalgae in Sphaerothalliod Circinaria spp. Lichens

Molins, A.; Moya, P.; García-Breijo, Francisco-José; Reig-Armiñana, José; Barreno, E. (Blackwell Publishing, 2018)

[EN] Three vagrant (Circinaria hispida, Circinaria gyrosa, Circinaria sp. `paramerae¿) and one crustose (semi-vagrant, Circinaria sp.`oromediterranea¿) growing in very continental areas in the Iberian Peninsula were selected ...
South European populations of Ramalina farinacea (L.) Ach. share different Trebouxia algae

Del Campo, Eva M.; Gimeno, José; De Nova, J.P.G.; Casano, Leonardo; Gasulla Vidal, Francisco; García-Breijo, Francisco-José; Reig Armiñana, José; Barreno Rodriguez, Eva (J. Cramer in der Gebrueder Borntraeger Verlagsbuchhandlung, 2010)

[EN] Little is currently known about the population structure of lichen photobionts. Accordingly, in this study we analyzed the nature and distribution of phycobionts in different Spanish populations of Ramalina farinacea. ...
The organic air pollutant cumene hydroperoxide interferes with NOantioxidant role in rehydrating lichen

Catalá, Miryam; Gasulla Vidal, Francisco; Pradas del Real, A.E.; García Breijo, Francisco José; Reig Armiñana, José; Barreno Rodriguez, Eva (Elsevier, 2013-08)

Organic pollutants effects on lichens have not been addressed. Rehydration is critical for lichens, a burst of free radicals involving NO occurs. Repeated dehydrations with organic pollutants could increase oxidative damage. ...
Two Trebouxia algae with different physiological performances are ever-present in lichen thalli of Ramalina farinacea. Coexistence versus Competition

Casano, L.; Del Campo, E.M.; García Breijo, Francisco José; Reig Armiñana, José; Gasulla, F.; del Hoyo, A.; Guéra, A.; Barreno, E. (WILEY-BLACKWELL, 2011-03)

Ramalina farinacea is an epiphytic fruticose lichen that is relatively abundant in areas with Mediterranean, subtropical or temperate climates. Little is known about photobiont diversity in different lichen populations. ...
