UV-B receptor recycling is needed for balanced plants’ sunscreen synthesis

Roman Ulm’s team provides further insight into the UV-B photoreceptor functioning, with the identification of a mechanism of reversion to ground state unique among photoreceptors. The molecular events are reported in the January 15th 2013 edition of PNAS. This study completes the various parts of the UV-B photoreceptor cycle, all identified by these researchers.
