Vitamin B12-auxotrophy in dinoflagellates caused by incomplete or absent cobalamin-independent methionine synthase genes (metE)

open access: yesFundamental Research, 2022
Dinoflagellates are responsible for most marine harmful algal blooms (HABs) and play vital roles in many ocean processes. More than 90% of dinoflagellates are vitamin B12 auxotrophs and that B12 availability can control dinoflagellate HABs, yet the ...

Biosynthesis of Saxitoxin in Marine Dinoflagellates: An Omics Perspective

open access: yesMarine Drugs, 2020
Saxitoxin is an alkaloid neurotoxin originally isolated from the clam Saxidomus giganteus in 1957. This group of neurotoxins is produced by several species of freshwater cyanobacteria and marine dinoflagellates.

The Goldilocks Effect: The Role of Temperature in Influencing Dinoflagellate Growth [PDF]

open access: yesCurrent: The Journal of Marine Education
Coral reef ecosystems, often referred to as the ‘rainforests of the sea,’ are vibrant ecosystems formed by millions of living coral polyps. Despite covering less than 1% of the ocean floor, coral reefs deliver vital benefits, including shoreline ...

Some Insights into the Inventiveness of Dinoflagellates: Coming Back to the Cell Biology of These Protists [PDF]

open access: yesMicroorganisms
In this review dedicated to the great protistologist Edouard Chatton (1883–1947), I wanted to highlight the originality and remarkable diversity of some dinoflagellate protists through the lens of cell biology.

OMICS Approaches to Assess Dinoflagellate Responses to Chemical Stressors

open access: yesBiology, 2023
Dinoflagellates are important primary producers known to form Harmful Algae Blooms (HABs). In water, nutrient availability, pH, salinity and anthropogenic contamination constitute chemical stressors for them.

Phytoplankton composition and abundance as indicators of aquaculture effluents impact in coastal environments of mid Gulf of California

open access: yesHeliyon, 2021
Composition and abundance of phytoplankton in two areas of Gulf of California, one near (ND) and one far (FD) from shrimp farms discharge, were studied in 3 seasons: late fall (farms finishing operations); spring (farms not operating); and summer (farms ...

Change in rheotactic behavior patterns of dinoflagellates in response to different microfluidic environments

open access: yesScientific Reports, 2021
Plankton live in dynamic fluid environments. Their ability to change in response to different hydrodynamic cues is critical to their energy allocation and resource uptake.
