Entry and exit of Fragilariopsis cylindrus diatoms from the polar night: evidence for chromatin-mediated genome control

This study examines how the polar diatom Fragilariopsis cylindrus regulates its epigenome during the polar night, showing stable repression of transposable elements through H3K27me3 and DNA methylation.

Genome wide assessment of genetic diversity and transcript variations in 17 accessions of the model diatom Phaeodactylum tricornutum

The paper assesses genetic and transcriptomic diversity in 17 Phaeodactylum tricornutum accessions, revealing increased genetic diversity and novel clades, while showing no link between sampling year and diversity loss.

Insights into the diversity and function of DNA methyltransferases in microeukaryotes using the model diatom Phaeodactylum tricornutum

The paper identifies and characterizes DNA methyltransferase diversity in marine microeukaryotes, showing that loss of DNMT5a leads to reduced DNA methylation and increased transposable element activity in diatoms.
