Inositol Pyrophosphates Mediate Chloroplast Lipid Remodeling and Nuclear Gene Repression during High-Light Acclimation in Chlamydomonas reinhardtii
Microalgae are photosynthetic organisms capable of autotrophic growth. Their applicability in multiple industrial fields has been largely studied, thanks to their ability to fixate CO2 into high added value organic products like fatty acids and carotenoids. However, our under-standing of the cellular signaling networks that control carbon flux and acclimation to envi-ronmental stress remains incomplete.
Chloroplast map reveals 'missing link' in plant growth and solar energy
For decades, science has understood the basics of photosynthesis, the process by which plants turn sunlight into food. However, photosynthesis occurs on uniquely specialized membranes that we have only begun to understand. These must be continually assembled, remodeled and repaired as plants grow and respond to stress.
Scientists got mouse eyes to perform photosynthesis — and no, they didn't turn green
Scientists got mouse eyes to perform photosynthesis — and no, they didn't turn green Special eye drops containing photosynthetic machinery from spinach leaves have helped combat dry eye, a new mouse experiment reveals. Scientists have developed new eye drops that allow mouse eyes to perform certain steps of photosynthesis. The drops, which contain photosynthetic machinery extracted from spinach leaves, use light-driven reactions to improve symptoms of dry eye disease, according to a study...
Why plant cells need heme: Hidden signal reshapes photosynthesis gene control
Why plant cells need heme: Hidden signal reshapes photosynthesis gene control Sadie Harley Scientific Editor Andrew Zinin Lead Editor For plants, light is an important environmental factor not only as a source of energy for photosynthesis, but also as a signal for capturing environmental information. Light signals are sensed by photoreceptor proteins called phytochromes. The amino acids that make up proteins are transparent and cannot absorb visible light.
Hidden protein switch controls photosynthesis as light conditions change
Hidden protein switch controls photosynthesis as light conditions change Andrew Zinin Lead Editor Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. The results, published in the journal Nature Plants, show how a crucial protein interaction at the interface between photosystems I and II controls the photosynthetic machinery.
Beans use an immune receptor to call in airstrikes on caterpillars
For decades, scientists have understood that plants can release volatile organic compounds—essentially airborne chemical signals—to attract the natural enemies of the things that eat them, like caterpillars. What we didn’t know was exactly how a plant translates the physical act of being eaten into a specific, predator-summoning distress signal. “[One] thing we didn’t know is how the plant detects the caterpillar in the first place,” says Adam Steinbrenner, a biologist at the University of...
Population genomics reveals divergent lineages in the European peatland plant Drosera rotundifolia
Genomic variation within populations reflects both past and contemporary evolutionary processes. The genetic structure of European peatland plants is shaped by complex postglacial recolonization and recent habitat loss. Here, we investigate population genomic patterns in the vulnerable peatland plant round-leaved sundew (Drosera rotundifolia L.).
Plastoglobules compartmentalize nitrogen assimilation in maize
Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10610-8Chloroplast plastoglobules act as nitrogen-assimilation hubs in maize, with key enzymes enhancing nitrogen-use efficiency and offering new strategies for developing high-yield, sustainable crops.
Topic modeling reveals thermally partitioned and taxonomically distinct microbial subcommunities across prokaryotes and phytoplankton in the Laurentian Great Lakes
Identifying discrete microbial assemblages and their environmental drivers across multiple biological fractions simultaneously remains a central challenge in aquatic microbial ecology. We applied an integrated analytical pipeline built around Latent Dirichlet Allocation (LDA) to an eight-year 16S rRNA amplicon time series from the Laurentian Great Lakes, spanning four size-fractionated biological blocks free-living prokaryotes, particle-associated prokaryotes, and small and large...
These underwater 'living pink rocks' help store carbon: Scientists just found four new species
These underwater 'living pink rocks' help store carbon: Scientists just found four new species Sadie Harley Scientific Editor Robert Egan Associate Editor Rhodoliths may look like small rocks on the seafloor, but they are actually living algae that create habitats for marine life and contribute to long-term carbon storage. A new study found that the deeper, low-light waters off Japan's Tanegashima Island harbor a surprisingly distinct and diverse community of these living pink rocks,...
