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

The paper studies early embryogenesis in Saccharina latissima, finding radical cell identity changes and gene expression patterns linked to evolutionary novelty.

The paper introduces LipoTag, a chemical motif that enables functional imaging of plant cell membranes by making hydrophobic fluorophores water-soluble and wall-permeable.

The paper introduces SBIS, a fluorescent probe for 4D imaging of brown algal cells, enabling 3D visualization of cell morphology during embryogenesis in multiple species.

CarboTag enables live functional imaging of plant cell walls by providing modular probes for multiplexing and quantifying key cell wall properties.

This paper investigates the role of a maternal signal (MUM) in establishing growth axes during kelp embryogenesis, showing that MUM inhibits medio-lateral axis formation and requires direct contact with the stalk.

The paper shows that actin filaments control alginate distribution in kelp embryos, forming a corset that restricts growth and establishes the apico-basal axis.

This study identifies a BAR-RhoGAP protein essential for tip growth in the brown alga Ectocarpus, functioning independently of F-actin organization.

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