An effective palynological preparation procedure using hydrogen peroxide [PDF]

open access: yes, 2007
Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively).

Chloroplast Ultrastructure and Photosynthetic Response of the Dinoflagellate Akashiwo sanguinea Throughout Infection by Amoebophrya sp.

open access: yesFrontiers in Marine Science, 2021
The endoparasitic dinoflagellate Amoebophrya infects a number of marine dinoflagellates, including toxic and harmful algal bloom-forming species. The parasite kills its host and has been proposed to be a determining factor in the demise of dinoflagellate

Sexual Reproduction in Dinoflagellates—The Case of Noctiluca scintillans and Its Ecological Implications

open access: yesFrontiers in Marine Science, 2021
Noctiluca scintillans is a larger, bioluminescent red-tide dinoflagellate (400–1,000 μm in diameter) that reproduces by sexual or asexual reproduction (binary fission). The process of sexual reproduction in N. scintillans has been thoroughly studied, but

Identification of Sequences Encoding Symbiodinium minutum Mitochondrial Proteins. [PDF]

open access: yes, 2016
The dinoflagellates are an extremely diverse group of algae closely related to the Apicomplexa and the ciliates. Much work has previously been undertaken to determine the presence of various biochemical pathways within dinoflagellate mitochondria ...

A Strategy for Gene Knockdown in Dinoflagellates

open access: yesMicroorganisms, 2022
Dinoflagellates are unicellular protists that display unusual nuclear features such as large genomes, condensed chromosomes and multiple gene copies organized as tandem gene arrays.

New organic-walled dinoflagellate cysts from recent sediments of central Asian seas [PDF]

open access: yes, 2004
Recent to sub-recent sediments from the Caspian Sea, the Kara-Bogaz-Gol Bay, the Enseli lake and the Aral Sea contain the new organic-walled dinoflagellate cysts Caspidinium, Caspidinium rugosum and Impagidinium caspienense.

Dinoflagellates, a Unique Lineage for Retrogene Research

open access: yesFrontiers in Microbiology, 2018
The birth and evolution of retrogenes have played crucial roles in genome evolution. Dinoflagellates represent a unique lineage for retrogene research because the retrogenes can be reliably identified by the presence of a 22 nucleotide splice leader ...
