Genome mining of mycosporine-like amino acid (MAA) synthesizing and non-synthesizing cyanobacteria: A bioinformatics study

open access: yesGenomics, 2010
Mycosporine-like amino acids (MAAs) are a family of more than 20 compounds having absorption maxima between 310 and 362 nm. These compounds are well known for their UV-absorbing/screening role in various organisms and seem to have evolutionary significance.

Peroxide scavenging potential of ultraviolet-B-absorbing mycosporine-like amino acids isolated from a marine red alga Bryocladia sp.

open access: yesFrontiers in Environmental Science, 2014
Ultraviolet-B (UV-B; 280-315 nm)-absorbing mycosporine-like amino acids (MAAs) were extracted and purified from a marine red alga Bryocladia sp. by using high performance liquid chromatography. We have detected four MAAs having retention times 3.23, 2.94,

Photoacclimation of cryptophytes and diatoms to light variability in the Western Antarctic Peninsula

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 643-665, April 2026.
Abstract Meltwater stratification during austral summer along the rapidly warming Western Antarctic Peninsula (WAP) exposes coastal phytoplankton to sudden light shifts. Such variability is thought to modulate phytoplankton dynamics, yet the photoacclimation capacity of Antarctic phytoplankton, especially cryptophytes, remains unclear.

Rapid Evolution in a Coral Population Following a Mass Mortality Event

open access: yesEvolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Globally, corals face an increased frequency of mass mortality events (MMEs) as populations experience repeated marine heatwaves which disrupt their obligate algal symbiosis. Despite greater occurrences of MMEs, the relative roles of the environment, host, and symbiont genetic variation in survival, subsequent recovery, and carry‐over effects ...

Packaging of mycosporine-like amino acids in dinoflagellates. [PDF]

open access: yes, 2004
Synthesis of mycosporine-like amino acids (MAAs) can significantly protect phytoplankton cells against damaging ultraviolet (UV) radiation, depending on the concentration, type and cellular distribution of these UV sunscreens. We addressed the hypothesis

UPLC‐QTOF‐MS–Based Metabolite Profiling of Two Laver Species (Neoporphyra dentata and Neopyropia yezoensis)

open access: yesJournal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
This study is aimed at characterizing metabolites from Neoporphyra dentata and Neopyropia yezoensis, two laver species primarily cultivated in Korea. Untargeted metabolite analysis was conducted using ultraperformance liquid chromatography–quadrupole time‐of‐flight mass spectrometry (UPLC‐QTOF‐MS), leading to the identification of 63 metabolites. These
