The photosystem I supercomplex from a primordial green alga Ostreococcus tauri harbors three light-harvesting complex trimers

This paper reports the structure and function of the photosystem I supercomplex in Ostreococcus tauri, showing it assembles with light-harvesting complexes and exhibits reversible photoacclimation.

Phosphorylation of light-harvesting complex II controls excitation energy spillover between photosystems

The paper shows phosphorylated LHCIIs in green algae mediate excitation energy spillover from PSII to PSI, enhancing photosynthetic adaptation under variable light conditions.

Environmental pH signals the release of monosaccharides from cell wall in coral symbiotic alga

The paper shows that low pH triggers cellulase-mediated release of monosaccharides from algal cell walls in coral symbionts.

Chlamydomonas State Transition Is Quiet Around Pyrenoid and Independent from Thylakoid Deformation

The paper investigates state transition in Chlamydomonas, finding reduced ST activity near the pyrenoid and structural changes independent of LHCII phosphorylation.

Photoprotection is regulated by light-independent CO2 availability

This study shows that CO2 availability, not light, directly regulates photoprotection and the CO2 concentrating mechanism in Chlamydomonas reinhardtii, with light indirectly influencing these processes by altering CO2 levels.

Structural basis of LhcbM5-mediated state transitions in green algae

The paper reports high-resolution structures of PSI-LHCI-LHCII supercomplex in green algae, revealing the role of LhcbM5 in state transitions and supercomplex formation.

UV-A/B radiation rapidly activates photoprotective mechanisms in Chlamydomonas reinhardtii

The paper shows that UV-A/B light activates photoprotective mechanisms faster than visible light in Chlamydomonas reinhardtii, suggesting a distinct UV response compared to land plants.

Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

This study sequenced the genome of a kleptoplastic sea slug and found no evidence of algal gene transfer to the nucleus, showing photosynthesis can occur without nuclear gene transfer.

Regulation of light harvesting in multimeric and monomeric photosystem II supercomplexes

The paper identifies monomeric and multimeric PSII-LHCII supercomplexes in spinach leaves and shows multimeric forms have higher light-harvesting but lower thermal dissipation capabilities under low-light conditions.
