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

Foliose algal assemblages and deforested barren areas: phlorotannin content, sea urchin grazing and holdfast community structure in the Aleutian dragon kelp, Eualaria fistulosa
Martin Schuster,Brenda Konar +1 more
TL;DR: Results show that phlorotannin content is greatest in areas under high grazing pressure and that phlootannins may possibly protect E. fistulosa and the holdfast communities from being grazed in barren areas.

What does the difference between the female and male gametophytes of Saccharina japonica remind us of
Yan-Hui Bi,Zhi-Gang Zhou +1 more
TL;DR: Whether S. japonica possesses a sex chromosome might be resolved by pairing the kelp sporophyte chromosomes with the help of localized repetitive sequences such as telomere and centromere using fluorescence in situ hybridization techniques.

In a squeeze: Epibiosis may affect the distribution of kelp forests.
TL;DR: Growth and survival of S. latissima is likely to be reduced by heavy loads of epibionts, while depths where epibions are sparse may be close to the lower limit of the kelps depth distribution along the south coast of Norway.

A molecular investigation of Saccharina sessilis from the Aleutian Islands reveals a species complex, necessitating the new combination Saccharina subsessilis
TL;DR: A molecular investigation of Saccharina sessilis from the Aleutian Islands reveals a species complex, necessitating the new combination Saccharine subsessilIS.

Characterization of mannitol metabolism genes in Saccharina explains its key role in mannitol biosynthesis and evolutionary significance in Laminariales
TL;DR: The considerable variation in enzyme characteristics and expression of mannitol synthesis genes suggest their important ecophysiological significance in the evolution of complex systems (filamentous and thallus) and environmental adaptation of Laminariales.

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.
