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

Mariculture of the Asian kelp Undaria pinnatifida and the native kelp Saccharina latissima along the Atlantic coast of Southern Europe: An overview
TL;DR: This review integrates key points about mariculture of kelp species from different cultivation trials conducted along the Atlantic coast of southern Europe, and more specifically about Undaria pinnatifida (wakame) and Saccharina latissima (sugar kombu) along the northern Spanish coast.

Seaweed Acclimation to Salinity and Desiccation Stress
TL;DR: This chapter focuses on the effects of changing salinities and desiccation on physiological processes in seaweeds such as growth, photosynthesis, and respiration as well as on osmotic acclimation.

Species delimitation, taxonomy, and biogeography of dictyota in europe (dictyotales, phaeophyceae)
Ana Tronholm,Frederique Steen,L. Tyberghein,Frederik Leliaert,Heroen Verbruggen,M. Antonia Ribera Siguan,Olivier De Clerck +6 more
TL;DR: In this paper, the diversity of the brown algal genus Dictyota in European waters was addressed using a molecular approach and necessary taxonomic changes were made to distinguish morphological plasticity from fixed diagnostic traits that separate the various species.

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.
