Bowazolo C, Song B, Dorion S, Beauchemin M, Chevrier S, Rivoal J, et al.
Proc Natl Acad Sci U S A
. 2022 Jul;
119(30):e2122335119.
PMID: 35858433
Many cells specialize for different metabolic tasks at different times over their normal ZT cycle by changes in gene expression. However, in most cases, circadian gene expression has been assessed...

Sci Total Environ
. 2019 Dec;
704:135430.
PMID: 31818571
Protein levels were assessed in the dinoflagellate Lingulodinium polyedra over the course of a diurnal cycle using a label-free LC-MS/MS approach. Roughly 1700 proteins were quantitated in a triplicate dataset...

Proteomics
. 2017 Nov;
18(1).
PMID: 29152876
Protein sequence identification by tandem mass spectroscopy (LC-MS/MS) identifies thousands of protein sequences even in complex mixtures, and provides valuable insight into the biological functions of different cells. For non-model...

Chromosoma
. 2017 Aug;
127(1):29-43.
PMID: 28852823
Dinoflagellate chromatin is unique among eukaryotes, as the chromosomes are permanently condensed in a liquid crystal state instead of being packed in nucleosomes. However, how it is organized is still...

PLoS One
. 2017 Jan;
12(1):e0168817.
PMID: 28103286
Dinoflagellates have been shown to express miRNA by bioinformatics and RNA blot (Northern) analyses. However, it is not yet known if miRNAs are able to alter gene expression in this...

mSphere
. 2016 Jun;
1(1).
PMID: 27303711
Roughly two-thirds of the proteins annotated as transcription factors in dinoflagellate transcriptomes are cold shock domain-containing proteins (CSPs), an uncommon condition in eukaryotic organisms. However, no functional analysis has ever...

BMC Biol
. 2014 Dec;

PMID: 25526979
Background: Almost all cells display circadian rhythms, approximately 24-hour period changes in their biochemistry, physiology or behavior. These rhythms are orchestrated by an endogenous circadian clock whose mechanism is based...

Beauchemin M, Roy S, Daoust P, Dagenais-Bellefeuille S, Bertomeu T, Letourneau L, et al.
Proc Natl Acad Sci U S A
. 2012 Sep;
109(39):15793-8.
PMID: 23019363
Dinoflagellates are an important component of the marine biota, but a large genome with high-copy number (up to 5,000) tandem gene arrays has made genomic sequencing problematic. More importantly, little...
