Cell position is the primary determinant of cell identity in the uniseriate filament of the brown alga Ectocarpus

The paper identifies cell position as the main factor determining cell identity in Ectocarpus filaments, with shape playing a secondary role.

Phytochromes Enable Social Behavior in Marine Diatoms

This study shows that phytochromes in marine diatoms enable light-mediated collective behavior through synchronized cell movements in response to blue or far-red light.

Latent endogenous viral elements drive active infection and inheritance in a multicellular host

The paper shows that endogenous viral elements in brown algae can reactivate, replicate, and transmit viruses, challenging the view of EVEs as inert.

DiatOmicBase, a gene-centered platform to mine functional omics data across diatom genomes

DiatOmicBase integrates public diatom omics data to connect genes to functional processes, enabling exploratory analysis and experiment design.

Acquisition of cell identity in the brown alga Ectocarpus: which of time, cell shape or position matters most?

The paper investigates how cell identity in Ectocarpus is influenced by age, shape, or position using transcriptomic analysis of mutant and wild-type strains.
