Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

Toxins of cyanobacteria and microalgae: a challenge for aquatic ecotoxicology

Boletim do Observatório Ambiental Alberto Ribeiro Lamego, 2010
The purpose of this review is to draw attention to the growing number of secondary metabolites produced by microorganisms in aquatic environments, specially cyanobacteria and marine microalgae. The first group is a producer of major hepatotoxins, neurotoxins and dermatotoxins.

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Cyanobacterial Toxins as Allelochemicals with Potential Applications as Algaecides, Herbicides and Insecticides

Marine Drugs, 2008
Cyanobacteria (“blue-green algae”) from marine and freshwater habitats are known to produce a diverse array of toxic or otherwise bioactive metabolites. However, the functional role of the vast majority of these compounds, particularly in terms

Iterative Genome Engineering Platform Enables Efficient Sucrose Biosynthesis From CO2 in Photosynthetic Synechococcus elongatus UTEX 2973

Plant Biotechnology Journal, EarlyView.
ABSTRACT The single crossover occurring via homologous recombination is a common phenomenon existing among microbes like Escherichia coli, Bacillus subtilis, Vibrio natriegens, Gluconobacter oxydans and most cyanobacteria species, threatening the stability of engineered strains and challenging iterative genetic engineering. Among them, we take the fast‐

Biosynthesis and Molecular Genetics of Polyketides in Marine Dinoflagellates

Marine Drugs, 2010
Marine dinoflagellates are the single most important group of algae that produce toxins, which have a global impact on human activities. The toxins are chemically diverse, and include macrolides, cyclic polyethers, spirolides and purine alkaloids ...

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...
