This month our paper “Acclimation of oxygenic photosynthesis to iron starvation is controlled by the sRNA IsaR1” has been published in the latest issue of Current Biology. IsaR1 is a regulatory RNA molecule that controls the acclimation of cells and especially of the photosynthetic machinery to limiting concentrations of bio-available iron. Please see also our press release and this comment. This work has been a productive collaboration among laboratories in 5 different countries.
