Diatom pyrenoids are encased in a protein shell that enables efficient CO2 fixation

This study identifies a protein shell surrounding diatom pyrenoids that enhances CO2 fixation efficiency and reveals its structural and functional role through in vivo and in vitro analyses.

A complex and dynamic redox network regulating oxygen reduction at photosystem I

The paper investigates how thiol-dependent redox networks regulate oxygen reduction at photosystem I in Arabidopsis under different photoperiods.

Low-CO2 inducible bestrophins in diatom thylakoid membranes sustain high photosynthetic efficacy at distant locations from the pyrenoid

This study identifies PtBST1 in diatoms as a bestrophin that facilitates HCO3- transport at the stroma thylakoid membrane, enhancing CO2 concentrating mechanism and modulating photoprotection.

Coral symbionts exhibit a polycistronic flavodiiron gene leading to functional proteins in photosynthesis

The paper identifies a polycistronic FLV gene in coral symbionts that produces functional proteins involved in photosynthesis, differing from the typical gene pair structure in other organisms.

A quantitative demonstration of NADP+/NADPH redox homeostasis in cyanobacterial cells

This study quantifies NADP+/NADPH redox homeostasis in cyanobacteria, showing that 64% of NADP(H) is non-light-responsive and limits the range of the NADP+/NADPH ratio.

Time-of-day dependent responses of cyanobacterial cellular viability against oxidative stress

This study shows that oxidative stress tolerance in cyanobacteria exhibits circadian rhythms, as demonstrated by time-of-day dependent cell viability changes under methyl viologen treatment.
