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

Sulfated Galactofucan from the Brown Alga Saccharina latissima—Variability of Yield, Structural Composition and Bioactivity
Karina Ehrig,Susanne Alban +1 more
TL;DR: It is demonstrated that habitat and harvest time of brown algae should be considered as factors influencing the yield as well as the composition and thus also the bioactivity of their SP.

Release and transformations of inorganic iodine by marine macroalgae
Rosie Chance,Alex R. Baker,Frithjof C. Küpper,Frithjof C. Küpper,Claire Hughes,Bernard Kloareg,Gill Malin +6 more
TL;DR: The release of iodide by macroalgae may impact upon the formation of volatile iodine species (molecular iodine and iodocarbons) that are of importance in the coastal atmosphere.
Journal ArticleDOI
Secondary production in a Laminaria hyperborea kelp forest and variation according to wave exposure
TL;DR: The results indicate that large quantities of Laminaria kelp are exported from the system, although the production of sessile animals was not taken into account, and the percentage of egg-carrying crustacean females and juveniles were lower than at medium and high exposure levels, thereby indicating lower fitness for animals at low exposure stations.
Journal ArticleDOI
Cultivation of a morphologically distinct strain of the sugar kelp, Saccharina latissima forma angustissima, from coastal Maine, USA, with implications for ecosystem services
TL;DR: Overall, this unique kelp form has the potential as a new aquaculture crop for the Gulf of Maine while providing several coastal ecosystem services.

The effect of light and nutrient availability on growth, nitrogen, and pigment contents of Saccharina latissima (Phaeophyceae) grown in outdoor tanks, under natural variation of sunlight and temperature, during autumn and early winter in Denmark
Teis Boderskov,Peter Søndergaard Schmedes,Annette Bruhn,Michael Bo Rasmussen,Mette Møller Nielsen,Morten Foldager Pedersen +5 more
TL;DR: Early winter harvest of S. latissima biomass grown under high nutrient availability in Denmark, fulfills a higher degree of nutrient bioremediation, and has an improved biomass quality in regards of increased concentrations of pigments and nitrogen rich compounds.

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.
Book
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.
