The paper investigates the molecular basis of life stage identity and reproductive mode in kelp, showing asexual reproduction is conditional and suppressed by mating partners.

The paper investigates the maternal-to-zygotic transition in brown algae, finding that zygotic genome activation occurs immediately after fertilization without stable parental imprinting, suggesting evolutionary flexibility in embryogenesis.

The paper uses linked-read whole-genome data to study reproductive isolation and hybridization patterns between two cryptic brown algal species, revealing polygenic genome-wide barriers to gene flow.

This study uses transcriptomic data from brown algae to show that regulatory evolution drives multicellular innovation despite conserved genome architecture.

The paper uses ribosome profiling to analyze translational regulation in Ectocarpus across developmental stages, finding widespread stage- and sex-specific control and post-transcriptional buffering.

The paper presents a lineage-wide evolutionary analysis of 3D genome architecture and organization across brown algae, revealing conserved chromosomal features, lineage-specific rearrangements, and long-term co-evolution of centromeres and retrotransposons.

The paper examines chromatin regulation in brown algae, showing loss of canonical silencing systems and emergence of H3K79 methylation as a repressive mechanism.

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

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.

The paper maps the 3D chromatin structure of sex chromosomes in the brown alga Ectocarpus, revealing their spatial organization and links to gene expression and sex determination.

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.

The paper investigates the molecular mechanisms of asexual reproduction emergence in brown algae, finding convergent gene expression changes and a key autosomal locus associated with the loss of sex.

The paper improves the genome of Aethionema arabicum using long-read sequencing and constructs a genetic map, enhancing genome assembly and enabling comparative genetic studies.
