1. Shedding Light on Shade- and Dark-Induced Leaf Senescence
Abstract : Leaf senescence is the final stage of leaf development, during which the leaf relocates most of itsvaluable nutrients to developing or storing parts of the plant. As this process progresses, leaves losetheir green color and their capacity to perform photosynthesis. READ MORE

2. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering
Abstract : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. READ MORE

4. Structural characterization of Deinococcus radiodurans phytochrome in solution
Abstract : Phytochromes are red/far-red photoreceptors which control a wide spectrum of biological processes inplants, fungi, and bacteria. Although phytochromes have been extensively studied, their mechanism ofaction still remains elusive. The signaling mechanism suggested by crystal structures involves refoldingof the so-called PHY tongue. READ MORE
