Prorocentrolide-A from Cultured Prorocentrum lima Dinoflagellates Collected in Japan Blocks Sub-Types of Nicotinic Acetylcholine Receptors [PDF]

Toxins, 2018
Prorocentrolides are members of the cyclic imine phycotoxins family. Their chemical structure includes a 26-membered carbo-macrocycle and a 28-membered macrocyclic lactone arranged around a hexahydroisoquinoline that incorporates the characteristic ...

Enhanced Toxicity of Diol-Estered Diarrhetic Shellfish Toxins Across Trophic Levels: Evidence from Caenorhabditis elegans and Mytilus galloprovincialis [PDF]

Marine Drugs
Prorocentrum lima is a widely distributed and major source of diarrhetic shellfish toxins (DSTs); the ecological impact of diol-estered DSTs (eDSTs) compounds on benthic systems is still inadequate.

Seasonal Transition in the Dominance of Photoautotrophic and Heterotrophic Protists in the Photic Layer of a Subtropical Marine Ecosystem. [PDF]

Environ Microbiol Rep
Amplicon sequencing showed a distinct seasonality in protist communities and functional strategies in a subtropical ecosystem in the Gulf of Aqaba. Temperature and nutrients were major drivers of succession. Comparisons with oceanwide Tara‐Ocean datasets indicated that the summer‐oligotrophic protist assemblages from the Gulf of Aqaba resemble those ...

Phylogeography and Diversity Among Populations of the Toxigenic Benthic Dinoflagellate Prorocentrum From Coastal Reef Systems in Mexico

Frontiers in Marine Science, 2021
The marine dinoflagellate genus Prorocentrum Ehrenberg comprises many species occupying primarily benthic or epiphytic habitats, particularly in tropical and sub-tropical waters.

Associated Bacteria and Their Effects on Growth and Toxigenicity of the Dinoflagellate Prorocentrum lima Species Complex From Epibenthic Substrates Along Mexican Coasts

Frontiers in Marine Science, 2020
The dinoflagellate genus Prorocentrum is globally represented by a wide variety of species found upon benthic and/or epiphytic substrates. Many epibenthic Prorocentrum species produce lipophilic polyether toxins, some of which act as potent protein ...

Functional redundancy of seasonal vitamin B12 biosynthesis pathways in coastal marine microbial communities

Environmental Microbiology, Volume 25, Issue 12, Page 3753-3770, December 2023., 2023
Our 7 years monthly metagenomic time series from the Mediterranean Sea demonstrates a seasonal succession of distinct potential vitamin B12 production pathways in summer (i.e., aerobic pathway) and winter (i.e., anaerobic pathway) carried by phylogenetically distant organisms (i.e., bacteria and archaea, respectively).

Diversity and putative interactions of parasitic alveolates belonging to Syndiniales at a coastal Pacific site

Environmental Microbiology Reports, Volume 15, Issue 3, Page 157-169, June 2023., 2023
Abstract The dinoflagellate lineage Syndiniales currently consists entirely of parasitic species that fall into five well‐supported clades. Environmental sequencing studies worldwide have found an abundance of Syndiniales in a variety of marine ecosystems, but very little is known about the majority of Syndiniales species including two entire clades ...
