To carry out their functions in the cell, many proteins require the chemical properties of bound metals such as copper. If this nutrient is in short supply, plants respond by enhancing its uptake and by replacing some copper-utilizing proteins by copper-independent proteins. Squamosa promoter binding protein-like 7 (SPL7) mediates this response. Researchers at Ruhr-Universität Bochum (RUB) have now discovered that SPL7 is also indispensable for plant energy metabolism.
