Effects of stressing high PAR on mycosporine-like amino acids in the red alga Gracilariopsis tenuifrons (Gracilariales, Rhodophyta)
(Society for Medicinal Plant and Natural Product ResearchGuimarães, 2014)
Studies in Rhodophyta species have been carried out to understand the mechanism of photoprotection against excessive photosynthetically active radiation (PAR). However, few studies concerning on the role of mycosporine-like ...
Analyses of photoprotective compounds in red algae from the Brazilian coast
(Sociedade Brasileira de Farmacognosia, 2011)
Qualitative and quantitative studies of mycosporine-like amino acids (MAAs) in three species of the genus Gracilaria Greville (G. birdiae, G. domingensis and G. tenuistipitata) were performed. A simple and efficient ...
UV-radiation effects on photosynthesis and photoprotection in gametophytic and sporophytic stages of the freshwater red alga Kumanoa ambigua (Rhodophyta, Batrachospermales)
(Wiley-Blackwell, 2018-04-01)
The aim of this study was to analyze the photosynthetic performance of gametophytic and sporophytic (Chantransia') stages of Kumanoa ambigua in culture under UV radiation. We hypothesized that both life history stages of ...
Mycosporine-like amino acids versus carrageenan yield in Mazzaella laminarioides (Gigartinales; Rhodophyta) under high and low UV solar irradiance
(2017)
The effects of increased solar photosynthetically active radiation (PAR) and ultraviolet radiation (UVR) on biomass, mycosporine-like amino acid (MAA) content, and carrageenan yield were studied for 14 days in tank-cultivated ...
Ammonium and UV Radiation stimulate the accumulation of mycosporine like amino acids in Porphyra columbina (Rhodophyta) from Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2004-12)
The combined effects of ammonium concentration and UV radiation on the red alga Porphyra columbina (Montagne) from the Patagonian coast (Chubut, Argentina) was determined using shortterm (less than a week) experimentation. ...
Tolerance to Ultraviolet Radiation of Psychrotolerant Yeasts and Analysis of Their Carotenoid, Mycosporine, and Ergosterol Content
(Springer, 2016)
Yeasts colonizing the Antarctic region are exposed to a high ultraviolet radiation evolving mechanisms to minimize the UV radiation damages, such as the production of UV-absorbing or antioxidant compounds like carotenoid ...
The relative contributions of diet and associated microbiota to the accumulation of UV-absorbing mycosporine-like amino acids in the freshwater copepod Boeckella antiqua
(Wiley Blackwell Publishing, Inc, 2012-05)
1. Mycosporine-like amino acids (MAAs) are ubiquitous compounds in aquatic organisms that are usually considered sunscreens that protect them from harmful ultraviolet radiation. Given that virtually all animals lack the ...
Photochemistry and photophysics of mycosporine-like amino acids and gadusols, nature's ultraviolet screens
(Int Union Pure Applied Chemistry, 2015-10)
Mycosporine-like amino acids (MAAs) and related gadusols are among the most prominent examples of metabolites suggested to act as UV-sunscreens. This review illustrates how experimental and theoretical studies on model ...
Photophysicochemical characterization of mycosporine-like amino acids in micellar solutions
(Royal Society of Chemistry, 2017-07)
The properties and photochemical and photophysical behavior of the mycosporine-like amino acids (MAAs) shinorine and porphyra-334 were experimentally evaluated in solutions of direct ionic micelles as simple biomimicking ...
