A vast number of artificial marine structures are currently installed offshore, and the rate of new installation is increasing. Especially offshore wind farms, a sub-type of artificial marine structures, are expected to grow significantly due to ambitious installation targets from international decision-makers. With increasing numbers of installed artificial marine structures, an assessment of possible adverse effects is more important than ever. To improve the environmental friendliness of artificial marine structures, an in-depth assessment of the transport and environmental fate of particle emissions is needed. The present work provides an overview of the involved processes of particle transport in the marine environment using the example of an offshore wind turbine. In this work, a first estimation on emission quantities is given for particulate emissions from marine structures, from which it is evident that emissions will increase in the next years due to an increasing number of marine structures.

is a long-established, well known and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from at least twice. Since, cladistically, this renders 'paraphyletic', it has been proposed that evolutionary clades be split into multiple genera (Runge et al.

The leaves of the cycad Encephalartos horridus exhibit a conspicuous glaucous appearance, attributed to the presence of epicuticular wax. However, the molecular and optical bases of this coloration have not been scientifically explained. In this study, we conducted a detailed analysis of the epicuticular wax composition, combined with RNA-Seq and de novo transcriptome assembly, to uncover the molecular mechanisms underlying this phenomenon.

Sesquiterpene synthases (STSs) catalyze carbocation cascade reactions with various hydrogen shifts and cyclization patterns that generate structurally diverse sesquiterpene skeletons. However, the molecular basis for hydrogen shifts and cyclizations, which determine STS product distributions, remains enigmatic. In this study, an elusive STS SydA was identified in the biosynthesis of sydonol, which synthesized a new bisabolene-type sesquiterpene with a unique saturated terminal pendant isopentane.

Macrocyclic peptides, including depsipeptides, are an emerging new modality in drug discovery research. Tetraselide, an antifungal cyclic peptide isolated from a marine-derived filamentous fungus, possesses a unique amphiphilic structural feature consisting of five consecutive β-hydroxy-amino acid residues and fatty acid moieties. Because the structure elucidation of the naturally occurring product left six stereocenters ambiguous, we implemented bioinformatic analyses, chemical degradation studies and chiral pool fragment synthesis to identify two of the undetermined stereocenters.
