Brown seaweeds are keystone species of coastal ecosystems, often forming extensive underwater forests, and under considerable threat from climate change. In this study, analysis multiple genomes has provided insights across the entire evolutionary history lineage, initial emergence, through later diversification brown algal orders, down to microevolutionary events at genus level. Emergence lineage was associated with a marked gain new orthologous gene families, enhanced protein domain rearrangement, increased horizontal transfer events, acquisition novel signaling molecules key metabolic pathways, latter notably related biosynthesis alginate-based extracellular matrix, halogen phlorotannin biosynthesis. We show that genome is tightly linked phenotypic divergence, including changes in life cycle strategy zoid flagellar structure.

10Vanadium-Dependent Haloperoxidase Gene Evolution in Brown Algae: Evidence for Horizontal Gene Transfer
International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(2), P. 716 - 716
Published: Jan. 16, 2025
Compared with green plants, brown algae are characterized by their ability to accumulate iodine, contributing ecological adaptability in high-iodide coastal environments. Vanadium-dependent haloperoxidase (V-HPO) is the key enzyme for iodine synthesis. Despite its significance, evolutionary origin of V-HPO genes remains underexplored. This study investigates genomic and dynamics V-HPOs algae, focusing on Laminariales species, particularly Saccharina japonica. Genomic analyses revealed extensive expansion gene family 88 identified S. japonica, surpassing number red algae. Phylogenetic analysis demonstrated distinct divergence between algal V-HPOs, clade closely related bacterial V-HPOs. These findings suggest horizontal transfer (HGT) played a role acquiring genes, from Acidobacteriota, phylum known plasticity. Additionally, enriched active transposable elements were around clusters, highlighting tandem duplications rapid HGT processes. Expression profiling further dynamic regulation response environmental conditions. provides new insights into how has driven kelp adaptations enhances understanding marine success

SUMMARY Brown seaweeds are keystone species of coastal ecosystems, often forming extensive underwater forests, that under considerable threat from climate change. Despite their ecological and evolutionary importance, this phylogenetic group, which is very distantly related to animals land plants, still poorly characterised at the genome level. Here we analyse 60 new genomes include all major brown algal orders. Comparative analysis these indicated occurrence several events coinciding approximately with emergence lineage. These included marked gain orthologous gene families, enhanced protein domain rearrangement, horizontal transfer acquisition novel signalling molecules metabolic pathways. The latter enzymes implicated in processes emblematic algae such as biosynthesis alginate-based extracellular matrix, halogen phlorotannin biosynthesis. early genomic innovations enabled adaptation intertidal habitats. subsequent diversification orders tended involve loss features were identified correlated differences life cycle strategy, flagellar structure metabolism. Analysis microevolutionary patterns within genus Ectocarpus deep flow between may be an important factor evolution on more recent timescales.

0The expanded Bostrychia moritziana genome unveils evolution in the most diverse and complex order of red algae
Current Biology, Journal Year: 2025, Volume and Issue: unknown
Published: May 1, 2025
Red algae are an ancient eukaryotic lineage that were among the first to evolve multicellularity. Although they share a common origin with modern-day plants and display complex multicellular development, comprehensive genome data from most highly evolved red algal groups remain scarce. Here, we present chromosome-level assembly of Bostrychia moritziana, seaweed in Rhodomelaceae family Ceramiales-the largest diverse order algae. Contrary view genomes typically small, report significant size expansion other Ceramiales, which represents one at least three independent events evolution. Our analyses suggest these expansions do not involve polyploidy or whole-genome duplications, but rather stem proliferation single giant Plavaka DNA transposons. Consistent its enlarged genome, has increased gene content shaped by de novo emergence amplified families providing insight into genetic adaptations underpinning this successful species-rich order. Finally, our sex-specific assemblies resolve UV sex chromosomes Bostrychia, feature expanded gene-rich sex-linked regions. Notably, each chromosome harbors amino acid loop extension homeodomain (TALE-HD) transcription factor orthologous regulators haploid-diploid transitions lineages. Together, findings offer unique perspective genomic driving diversity demonstrate how can provide evolutionary origins universal principles

2Sustainable seaweed aquaculture and climate change in the North Atlantic: challenges and opportunities
Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11
Published: Oct. 22, 2024
Seaweed aquaculture is gaining traction globally as a solution to many climate issues. However, seaweeds themselves are also under threat of anthropogenically driven change. Here, we summarize climate-related challenges the seaweed industry, with focus on developing trade in North Atlantic. Specifically, three main challenges: i) abiotic change; ii) extreme events; and iii) disease & herbivory. Abiotic change includes negative effects ocean warming acidification, well altered seasonality due warming. This can lower biomass yield biochemical composition seaweeds. Extreme events cause considerable damage loss farms, particularly marine heatwaves, storms freshwater inputs. diseases have higher chance proliferating environmentally stressful conditions such decreased salinity. Herbivory causes but not researched relation Despite challenges, opportunities exist improve resilience change, summarized sections: future proof site selection; advances breeding microbiome manipulation; restorative aquaculture. We present case study where use predictive modelling illustrate suitable habitat for cultivation Atlantic Notably, there was large cultivating Alaria esculenta Laminaria digitata . show how selection priming microbe inoculates may be cost-effective scalable disease- thermal tolerance. Co-cultivation increase both biodiversity co-benefits. Finally, that restoration benefit from collaborating nursery techniques push improved legislation.

Abstract The evolution of multicellularity led to the origin new kinds organisms and, in several lineages, massive adaptive radiations through formation entirely ecosystems. This paper examines three key mechanisms underpinning parallel within five clades ‘complex’ multicellularity: animals, land plants, fungi, red algae, and brown algae. First, multicellular innovations permitted diversification into ecological roles. Second, large with strong genetic bottlenecks between generations fundamentally changed population context evolution, greatly reducing effective size increasing role drift. may be beneficial during radiations, nonadaptive expansions genome allowing broader exploration trait space. Finally, we explore how evolutionary priority effects provide a first-mover advantage, maintaining ancient over long time periods by suppressing competition from convergently evolving taxa. Investigating patterns across independent origins complex provides insight principles these crucially important radiations.
