Phosphorylation of MAPK-like proteins in three intertidal macroalgae under stress conditions

Molecular response of Sargassum vulgare to acidification at volcanic CO2 vents: insights from de novo transcriptomic analysis

“…Briefly, the induction of calcium signalling in acidification response is highlighted by the upregulation of a specific transcript predicted in MAPMAN to encode for calmodulin with possible function in thigmomorphogenesis, a complex plant response to abiotic stimuli. Furthermore, the upregulation of transcripts encoding Rab/RasGTPase and MAPK suggests that MAPK signalling cascades may be also involved in mechanism of response to OA, as also demonstrated in intertidal macroalgae (Parages et al 2014). The regulation of cyclic adenosine 3 0 ,5 0 -monophosphate (cAMP) in S. vulgare may contribute to the acclimatization to elevated CO 2 areas, as also reported for the diatom T. pseudonana (Hennon et al 2015).…”

Short-term effects of increasing CO2, nitrate and temperature on three Mediterranean macroalgae: biochemical composition

“…The experiments were conducted in the framework of the International Workshop of the Group on Aquatic Primary Productivity (GAP 9) hosted in September 2012, in Málaga. In addition to this study, the results of the experiments on these macroalgae have been presented in other reports , Figueroa et al 2014a, Parages et al 2014; all this Theme Section).…”

Coralline Algae in a Changing Mediterranean Sea: How Can We Predict Their Future, if We Do Not Know Their Present?

“…More recent studies investigated populations of Ellisolandia elongata from the Alboran Sea, highlighting several metabolic features that make this alga well-adapted to withstand the environmental stresses typical of its interidal habitat (Celis-Plá et al, 2014;Figueroa et al, 2014a;Korbee et al, 2014;Parages et al, 2014;Stengel et al, 2014). This alga is able to improve its photoprotective capacity by regulating its content in mycosporine-like aminoacids (MAAs, compounds well-known for their photoprotective role in numerous algae) in response to environmental conditions (Celis-Plá et al, 2014;Korbee et al, 2014).…”

Stengel et al (2014) demonstrated a reduction in the effective photosystem II quantum efficiency in the central hours of the day, and showed that the highest phycocyanin content occurred in the evening; Parages et al (2014) performed proteomic studies on the same samples and concluded that mitogen-activated protein kinase (MAPK)-like proteins are involved in the response of this species to environmental stress. Figueroa et al (2014b) argued that the species is resistant to UVBradiation thanks to the high reflectance of its calcareous thallus.…”
