Publikováno v: Photochemical & Photobiological Sciences. 18:400-412

We studied the effects of different radiation treatments on the physiology and UV-absorbing compounds of the model liverwort Marchantia polymorpha subsp. ruderalis. Starting from gemmae, samples were exposed to five radiation treatments: low photosyn

Ultraviolet (UV) radiation strongly influences grape composition, but only a few studies have focused on how this influence is conserved in the resulting wines. Here we analyzed to what extent the changes induced by exposing Tempranillo grapes to UV

Publikováno v: Science of The Total Environment. :248-257

The spatial variability of ultraviolet-absorbing compounds (UVACs) in the freshwater liverwort Jungermannia exsertifolia subsp. cordifolia was studied in mid-latitudes (the Atlantic-Mediterranean transition) across a wide lati-altitudinal gradient, w

Ultraviolet-absorbing compounds from the cell walls of an aquatic liverwort are more efficiently extracted by alkaline than by enzymatic digestion

Autor: Gabriel Fabón, Rafael Tomás-Las-Heras, Encarnación Núñez-Olivera, Laura Monforte, María Ángeles Del-Castillo-Alonso, Javier Martínez-Abaigar

Publikováno v: Journal of Bryology. 37:8-14

The accumulation of ultraviolet-absorbing compounds (UVACs) within the cell walls of bryophytes provides a spatially uniform filter of ultraviolet-B (UV-B) radiation, and thus represents an important protective mechanism against its adverse effects.

Autor: Javier Martínez-Abaigar, Rafael Tomás-Las-Heras, Encarnación Núñez-Olivera, Gabriel Fabón, Laura Monforte

Publikováno v: Journal of plant physiology. 169(1)

We studied the diel responses of the liverwort Jungermannia exsertifolia subsp. cordifolia to radiation changes under laboratory conditions. The samples were exposed to three radiation regimes: P (only PAR), PA (PAR+UV-A), and PAB (PAR+UV-A+UV-B). Th
