This study identifies conserved gene expression patterns across the life cycles of brown algae by comparing transcriptomes of gametophyte and sporophyte stages in multiple species.

This study characterizes the U and V sex chromosomes in red algae, revealing their evolutionary origin and structural features, and highlights their role in sex determination.

The paper analyzes brown algal genomes to trace the origin and evolution of U/V sex chromosomes, revealing gene gain-driven evolution and the demise of these systems through hermaphroditism and gene hierarchy shifts.

The paper investigates sexual differentiation in a U/V sex chromosome system using giant kelp, identifying key genes and transcriptome changes associated with male and female development.

This study analyzes 60 brown algal genomes to identify genomic innovations and evolutionary patterns that enabled their adaptation to coastal ecosystems.

The paper investigates the evolutionary origins of extracellular matrix polysaccharides in brown algae using genomic data and comparative analysis.

This study investigates the genetic and molecular interactions between U and V sex chromosomes in the brown alga Ectocarpus across its life cycle, revealing developmental regulation and histone modifications in the diploid sporophyte stage.

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

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

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

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