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

Large-scale hatchery of the kelp Saccharina japonica: a case study experience at Lvshun in northern China
TL;DR: The entire process of a commercial hatchery manipulation in the 2015 production season at Lvshun, Dalian, northern China, is presented, including pre-treatment of parental plants, control of spore release, and control and adjustment of solar irradiance and temperature at different developmental stages of the plants as well as the nutrient supply regime over the entire course.

Survival of early life history stages of Arctic kelps (Kongsfjorden, Svalbard) under multifactorial global change scenarios
TL;DR: It is concluded that the structure of kelp communities can be shaped by abiotic and biotic variables acting on early developmental stages and that global warming has the potential to alter the strengths and direction of these effects, which may lead to future shifts in the community structure.

Ocean acidification and kelp development: Reduced pH has no negative effects on meiospore germination and gametophyte development of Macrocystis pyrifera and Undaria pinnatifida.
Pablo P. Leal,Pablo P. Leal,Catriona L. Hurd,Catriona L. Hurd,Pamela A. Fernández,Pamela A. Fernández,Michael Y. Roleda +6 more
TL;DR: The microscopic stages of the native M. pyrifera and the invasive U. pinnatifida will respond similarly to ocean acidification, indicating that the early life stages of large macroalgae such as kelps will respondSimilarly to OA.

TL;DR: The recently described sequence of the sex determining region (SDR) of the brown algal model Ectocarpus is used to develop novel DNA-based sex-markers for three commercially relevant kelps: Laminaria digitata, Undaria pinnatifida and Macrocystis pyrifera.

Recent developments in aquaculture of Palmaria palmata (Linnaeus) Weber & Mohr 1805): cultivation and uses
TL;DR: The possibilities of cultivation of P. palmata enhance the prospects for the expansion of the cultivation of this seaweed, however, future research is needed regarding balance of culture conditions, costs and biomass in land-based tank culture and in terms of site selection, system design, maintenance and harvest techniques in sea cultivation.

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.
