OsNF-YB7, an ortholog of Arabidopsis LEC1, is a negative regulator of Chl biosynthesis in rice embryos by interacting with OsGLK1 to inhibit the transactivity of OsGLK1.

Cyanobacteria with chlorophyll f show substantial near-infrared radiation-driven photosynthesis and can play an important role for primary production in endolithic, intertidal habitats.

The structure of the photosystem I (PSI) supercomplex in Ostreococcus tauri has revealed a unique hybrid of both plant-type and green algal-type PSI supercomplexes with three Lhcp trimers located at the ‘state 2’ position.

SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.

The molecular mechanisms of FCPI assembly and selective binding are revealed through comparison of PSI-FCPI structures in two diatom species.

An in silico reconstruction of a chloroplast that existed hundreds of millions of years ago casts new insights in the evolutionary processes, endosymbioses and chimerism events that shape the origin of plastids.

Euryhaline green algae utilise intracellular osmoprotectant modulation and specialised redox enzyme networks to successfully inhabit a desert coastline.

The crystal structure of higher plant PSI-LHCI complex reveals intricate details responsible for light harvesting.

The algal pyrenoid is formed at high O₂ levels, even when CO₂ is high, implying that a product of photosynthesis, most likely H₂O₂ acts as a signal.

Comparisons of enzyme efficiency and electron transfer show that, to oxidize water using lower energy light, the two types of far-red photosystem II have adopted opposite trade-offs between efficiency of light use and resilience to light damage.
