The paper shows oxygen drives a reversible photoprotective switch in photosynthetic antennae by stabilizing a charge-separated state that reduces photodamage.

The paper describes a novel repression-derepression mechanism for Staphylococcus aureus pathogenicity islands (SaPIs) involving tetrameric repressors and an inducing protein.

The paper characterizes the photocycle of a blue-orange cyanobacteriochrome in Synechococcus sp. PCC 7002, showing it cycles between orange and blue light-absorbing states with specific chromophore isomers and cysteine residues involved.
