Subcellular Localization of Carotenoid Biosynthesis in Synechocystis sp. PCC 6803. [PDF]
The biosynthesis pathway of carotenoids in cyanobacteria is partly described. However, the subcellular localization of individual steps is so far unknown. Carotenoid analysis of different membrane subfractions in Synechocystis sp.

Current rectification via Photosystem I monolayers induced by their orientation on hydrophilic self-assembled monolayers on titanium nitride [PDF]
Photosystem I (PSI) is a photosynthetic protein which evolved to efficiently transfer electrons through the thylakoid membrane. This remarkable process attracted the attention of the biomolecular electronics community, which aims to study and understand the underlying electronic transport through these proteins by contacting ensembles of PSI with solid-

Functional and mutational analysis of the light-harvesting chlorophyll a/b protein of thylakoid membranes. [PDF]
The precursor for a Lemna light-harvesting chlorophyll a/b protein (pLHCP) has been synthesized in vitro from a single member of the nuclear LHCP multigene family. We report the sequence of this gene.

Single and Double Knockouts of the Genes for Photosystem I Subunits G, K, and H of Arabidopsis [PDF]
Photosystem I (PSI) of higher plants contains 18 subunits. Using Arabidopsis En insertion lines, we have isolated knockout alleles of the genes psaG, psaH2, and psaK, which code for PSI-G, -H, and -K.

Photoinduced Electron Transfer Across Phospholipid Bilayers in Anaerobic and Aerobic Atmospheres
Light‐driven transmembrane electron transfer across a biomimetic lipid bilayer membrane in aerobic and anaerobic atmospheres is achieved using an organic transmembrane oriented chromophore. The transmembrane molecule is designed symmetrically and easy to synthesize.

Ultrastructure changes of seedlings of Kosteletzkya virginica under waterlogging conditions
The changes in ultrastructure of leaf cell in waterlogged Kosteletzkya virginica seedlings were observed by transmission electron microscope. During waterlogging, the chloroplasts turned into a round shape and their volume was gradually reduced ...

Selective light‐driven CO2 to CO reduction by a [FeFe]‐hydrogenase mimic in water
We report a biomimetic system for light‐driven CO2 conversion in lipid bilayers using a [FeFe]‐hydrogenase‐inspired molecular dyad (PS‐CAT) acting simultaneously as photosensitizer and catalyst. The molecular design of PS‐CAT consists of both light‐harvesting and catalytically active moieties in a single molecule.
