Comparison of the performance of sporophytes derived from narrow and wide genetic crosses between strains of the cultivated kelp Saccharina latissima

This study compares local and wide genetic crosses in kelp to assess breeding effectiveness without introducing foreign genetic material.

Radical cell identity bifurcation in Saccharina embryos coincides with the expression of newly acquired genes.

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

The genome of the Delisea pulchra: a resource for the study of chemical host-microbe interactions in red algae

The baseless mutant links protein phosphatase 2A with basal cell identity in the brown alga Ectocarpus

This study identifies the BASELESS gene as encoding a PP2A regulatory subunit essential for initial cell division and basal cell fate establishment in Ectocarpus.

Tip growth in the brown alga Ectocarpus is controlled by a RHO-GAP-BAR domain protein independently from F-actin organisation

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

Chromosome-level quality scaffolding of brown algal genomes using InstaGRAAL, a proximity ligation-based scaffolder

The paper introduces instaGRAAL, a Hi-C-based scaffolder that improves chromosome-level genome assemblies for brown algae.

Convergent recruitment of life cycle regulators to direct sporophyte development in two eukaryotic supergroups

This study shows that TALE HD TFs regulate sporophyte development in two eukaryotic supergroups, indicating an ancient origin of this regulatory system.
