Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

New Phytologist, Volume 250, Issue 6, Page 3885-3899, June 2026.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non‐Photochemical Quenching in the Absence of PsbS and Zeaxanthin

Plant, Cell &Environment, Volume 49, Issue 6, Page 3405-3425, June 2026.
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...

Identifying the Environmental Drivers of Spatial Variability in Zooplankton Community Grazing Dynamics

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Biogeochemical models used to estimate carbon export fluxes are highly sensitive to their parameterization of zooplankton grazing dynamics. Zooplankton grazing dynamics have been shown to vary spatially, however it is less clear how they are responding to underlying environmental drivers.

Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).
