A combination of phylogenetic and biochemical analyses suggest that some unexpected variations in the synthesis of isoprenoids may be widespread across all three domains of life.

The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

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.

A general framework captures the evolutionary routes leading to the formation and progression of tumors.

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

The transcription factor bZIP63 is a key regulator of the starvation response in the model plant Arabidopsis thaliana and is directly targeted by the kinase SnRK1.

The cells of a cyanobacterium act as spherical micro-lenses, allowing the cell to see a light source and move towards it.
