Predatory cues drive colony size reduction in marine diatoms [PDF]

Ecology and Evolution, 2021
Colony formation is a common feature among nonmotile marine phytoplankton. Several theories exist around the potential benefits of larger colonies. Here, we test the hypothesis that predation is one of the drivers behind colony formation and chain length

Influence of Nitrate and Light on Fucoxanthin Content and Key Gene Expression in the Marine Diatom Thalassiosira rotula [PDF]

Plants
Fucoxanthin is the predominant carotenoid in diatoms, playing a central role in light harvesting and photoprotection, and is increasingly valued for its potential in pharmaceutical, nutraceutical, and cosmetic applications. In this study, we investigated

High-quality genome assembly and annotation of Thalassiosira rotula (synonym of Thalassiosira gravida) [PDF]

Scientific Data
Diatoms are unicellular eukaryotic microorganisms thriving in most aquatic environments thanks to the expression of biosynthetic pathways for secondary metabolites involved in defence and adaptation to environmental changes.

Conductive Hairy Particles With Homogeneous and Janus Design as Carrier Materials for the Efficient Immobilization of Unspecific Peroxygenases. [PDF]

Biotechnol J
Graphical Abstract and Lay Summary Efficient immobilization of unspecific oxidoreductases on hairy core‐shell particles with homogeneous and Janus design possessing conductive core material and polymeric brush shell is demonstrated. PDMAEMA brushes with controlled chain lengths (4, 11, and 23 nm) are successfully grown from conductive silver particles.

Adaptation and Plasticity of <i>Nannochloropsis</i> sp. in Response to Seasonal and Geographic Climate Variation. [PDF]

Evol Appl
ABSTRACT Phytoplankton respond to their environment through genetic adaptation and plasticity to maintain fitness. This poses challenges when growing microalgae for industrial applications because, inherently, outdoor mass cultivation may lead to adaptations that alter desirable phenotypic traits and environmental niches.

Exploring Unspecific Peroxygenase Selectivity with Diverse Hydrocarbon Substrates. [PDF]

ChemistryOpen
Unspecific peroxygenases (UPOs) are versatile enzymes that can be used for different reactions. However, selectivity of UPOs needs to be evaluated for the desired application. Thus, the selectivity of a panel of UPOs was evaluated in this work, and it revealed diverse reactivity profiles depending on the enzyme and substrate.

Monitoring Alien Species Diversity in Ballast Water Based on Environmental DNA Metabarcoding. [PDF]

Ecol Evol
This study applied environmental DNA (eDNA) metabarcoding to assess alien species in ballast water from ships at Dongjiakou Port, Qingdao, identifying 41 alien species including three invasives. The findings demonstrate the effectiveness of eDNA as a noninvasive tool for monitoring ballast water biodiversity and offer valuable insights for managing the

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...
