Alternation of Generations in Plants and Algae
Photosynthetic organisms are found in most of the branches of the eukaryotic tree of life, and these organisms have diverse life cycles. There has been a tendency toward dominance of the diploid phase of the l...

Open AccessEctocarpus: an evo-devo model for the brown algae
Ectocarpus is a genus of filamentous, marine brown algae. Brown algae belong to the stramenopiles, a large supergroup of organisms that are only distantly related to animals, land plants and fungi. Brown algae ar...

Open AccessMorphological, genotypic and metabolomic signatures confirm interfamilial hybridization between the ubiquitous kelps Macrocystis (Arthrothamnaceae) and Lessonia (Lessoniaceae)
Macrocystis pyrifera and Lessonia spicata are economically and ecologically relevant brown seaweeds that recently have been classified as members of two separated families within Laminariales (kelps). Here we des...

Open AccessOrganelle inheritance and genome architecture variation in isogamous brown algae
Among the brown algal lineages, Ectocarpales species have isogamous fertilization in which male and female gametes are morphologically similar. In contrast, female gametes are much larger than male gametes in ...

Open AccessJuvenile morphology of the large Antarctic canopy-forming brown alga, Desmarestia menziesii J. Agardh
For many types of seaweeds in Polar Regions, open questions remain about how their life cycle contributes to their overall adaptation to the extreme abiotic environment. This applies in particular to the major...

Open AccessCorrection to: Rapid turnover of life-cycle-related genes in the brown algae
Following publication of the original article [1], it was noticed that the author names were published with initials instead of full names. The article [1] has been updated.

Open AccessRapid turnover of life-cycle-related genes in the brown algae
Sexual life cycles in eukaryotes involve a cyclic alternation between haploid and diploid phases. While most animals possess a diploid life cycle, many plants and algae alternate between multicellular haploid ...

Open AccessqPCR-based relative quantification of the brown algal endophyte Laminarionema elsbetiae in Saccharina latissima: variation and dynamics of host—endophyte interactions
Morphological changes—such as dark spots, twisted stipes and deformed blades—have been observed in wild and cultivated Saccharina latissima. The putative cause for the disease symptoms is the filamentous endophyt...

Open AccessMultiple gene movements into and out of haploid sex chromosomes
Long-term evolution of sex chromosomes is a dynamic process shaped by gene gain and gene loss. Sex chromosome gene traffic has been studied in XY and ZW systems but no detailed analyses have been carried out f...

Open AccessThe Mediterranean deep-water kelp Laminaria rodriguezii is an endangered species in the Adriatic Sea
Deep-water kelps are little-known large brown algae occurring close to the lower limit of photosynthetic life in the sea. This study compares historical and recent records of the deep-water Mediterranean kelp Lam...

Emergence of Ectocarpus as a Model System to Study the Evolution of Complex Multicellularity in the Brown Algae
In contrast to the situation in land plants and animals, very little information is available concerning the molecular mechanisms underlying multicellular development in the brown algae. Historically, one of t...

Seaweed biodiversity in the south-western Antarctic Peninsula: surveying macroalgal community composition in the Adelaide Island/Marguerite Bay region over a 35-year time span
The diversity of seaweed species of the south-western Antarctic Peninsula region is poorly studied, contrasting with the substantial knowledge available for the northern parts of the Peninsula. However, this ...

Open AccessPlastid genomes of two brown algae, Ectocarpus siliculosus and Fucus vesiculosus: further insights on the evolution of red-algal derived plastids
Heterokont algae, together with cryptophytes, haptophytes and some alveolates, possess red-algal derived plastids. The chromalveolate hypothesis proposes that the red-algal derived plastids of all four groups ...

Oligoalginate Recognition and Oxidative Burst Play a Key Role in Natural and Induced Resistance of Sporophytes of Laminariales
Forty-five species of brown algae (Phaeophyceae) were surveyed for their capacity to respond by an oxidative burst to challenges with alginate oligosaccharides. Intertidal frondose brown algae (Fucales) consti...
