Origin and evolutionary trajectories of brown algal sex chromosomes

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.

A partially sex-reversed giant kelp sheds light into the mechanisms of sexual differentiation in a UV sexual system

The paper identifies a partially sex-reversed giant kelp strain, revealing transcriptional changes and gene expression patterns associated with sexual differentiation in a UV sexual system.

Revisiting Australian Ectocarpus subulatus (Phaeophyceae) from the Hopkins River: distribution, abiotic environment, and associated microbiota

The paper revisits Ectocarpus subulatus in the Hopkins River, finding it has stably colonized the area and reports new microbiota associated with the algae.

Evolution of life cycles and reproductive traits: insights from the brown algae

This study examines the evolution of life cycle and reproductive traits in brown algae, finding diploid growth may evolve due to mutation complementation and haploid sex determination is ancestral.

A key role for UV sex chromosomes in the regulation of parthenogenesis in the brown alga Ectocarpus

The paper identifies the genetic basis of parthenogenesis in Ectocarpus, showing the sex locus and two autosomal loci regulate asexual reproduction and reveal fitness trade-offs between haploid and diploid stages.

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.

Rapid turnover of life-cycle-related genes in the brown algae

The paper examines generation-biased gene expression in brown algae, finding high turnover rates and distinct evolutionary patterns between gametophyte and sporophyte genes.
