TLDR
This review about the genus Laminaria sensu lato summarizes the extensive literature that has been published since the overview of the genus given by Kain in 1979, and covers recent insights into phylogeny and taxonomy, and discusses morphotypes, ecotypes, population genetics and demography.Abstract:
This review about the genus Laminaria sensu lato summarizes the extensive literature that has been published since the overview of the genus given by Kain in 1979. The recent proposal to divide the genus into the two genera Laminaria and Saccharina is acknowledged, but the published data are discussed under a 'sensu lato' concept, introduced here. This includes all species which have been considered to be 'Laminaria' before the division of the genus. In detail, after an introduction the review covers recent insights into phylogeny and taxonomy, and discusses morphotypes, ecotypes, population genetics and demography. It describes growth and photosynthetic performance of sporophytes with special paragraphs on the regulation of sporogenesis, regulation by endogenous rhythms, nutrient metabolism, storage products, and salinity tolerance. The biology of microstages is discussed separately. The ecology of these kelps is described with a focus on stress defence against abiotic and biotic factors and the role of Laminaria as habitat, its trophic interactions and its competition is discussed. Finally, recent developments in aquaculture are summarized. In conclusion to each section, as a perspective and guide to future research, we draw attention to the remaining gaps in the knowledge about the genus and kelps in general.read more

The German Case Study: Pioneer Projects of Aquaculture-Wind Farm Multi-Uses
Bela H. Buck,Gesche Krause,Bernadette Pogoda,Britta Grote,Lara Wever,Nils Goseberg,Maximilian Felix Schupp,Arkadiusz Mochtak,Detlef Czybulka +8 more
TL;DR: In this chapter the findings of a series of mussel and oyster cultivation experiments over several seasons are presented, which were conducted at different offshore test sites in the German Bight and primary focus on the economic potential of aquaculture in offshore wind farms was shown for consumption mussels.

Whole genome survey of the glutathione transferase family in the brown algal model Ectocarpus siliculosus
TL;DR: Gene structure and phylogenetic analyses demonstrated the partition of the Sigma GSTs into two clusters which have probably evolved by duplication events and suggested that E. siliculosus GST genes are recruited in different and specific conditions.

Abiotic regulation of investment in sexual versus vegetative reproduction in the clonal kelp laminaria sinclairii (laminariales, phaeophyceae)1
Kyle W. Demes,Michael H. Graham +1 more
TL;DR: Results suggest that regulation of growth and investment in sexual reproduction in L. sinclairii is similar to that in aclonal kelps (i.e., warmer temperatures result in decreased reproductive output) and depletion of carbon and nitrogen from rhizomes in suboptimal conditions confirms the role of clonal kelp rhZomes in carbon and nutrient storage.

Seasonal growth patterns of Saccharina latissima (Phaeophyceae, Ochrophyta) in a glacially-influenced subarctic estuary
Tania Spurkland,Katrin Iken +1 more
TL;DR: Klp, Saccharina latissima, from a glacially‐influenced and an oceanic shore in a subarctic Alaskan estuary exhibits differing seasonal growth patterns in response to its environment, suggesting it is a highly resilient species.

Genome-Scale Metabolic Networks Shed Light on the Carotenoid Biosynthesis Pathway in the Brown Algae Saccharina japonica and Cladosiphon okamuranus

TL;DR: The potential of GSMNs reconstructions for formalizing hypotheses that can be further tested using targeted biochemical approaches is illustrated and, if abscisic acid is produced by Saccharina japonica, its biosynthesis pathway seems to be different in its final steps from that described in land plants.

Organic osmolytes as compatible, metabolic and counteracting cytoprotectants in high osmolarity and other stresses
TL;DR: Organic osmolytes are small solutes used by cells of numerous water-stressed organisms and tissues to maintain cell volume and have applications in biotechnology, agriculture and medicine, including in vitro rescue of the misfolded protein of cystic fibrosis.

Algae: An Introduction to Phycology
David G. Mann,H.M Jahns +1 more
TL;DR: In this article, the main groups of algae (divisions or phyla) are considered in turn, and the final chapter is a synthesis, in which the phylogeny of the algae is discussed in relation to the evolution of other living organisms.

CONSTANS mediates between the circadian clock and the control of flowering in Arabidopsis
Paula Suárez-López,Kay Wheatley,Frances Robson,Frances Robson,Hitoshi Onouchi,Hitoshi Onouchi,Federico Valverde,George Coupland,George Coupland +8 more
TL;DR: It is shown that expression of CONSTANS (CO), a gene that accelerates flowering in response to long days, is modulated by the circadian clock and day length, suggesting mechanisms by which day length regulates flowering time.

Direct and Indirect Effects
TL;DR: A new way of defining the effect transmitted through a restricted set of paths, without controlling variables on the remaining paths is presented, which permits the assessment of a more natural type of direct and indirect effects.
