A plant can reproduce successfully only if it flowers at the appropriate time. Therefore, a complex network of photoreceptors and other proteins has evolved to monitor environmental conditions such as light and temperature. It has long been thought that plants must also ensure that they have sufficient resources for the energy intensive process of building flowers. As scientists from the Max Planck Institute of Molecular Plant Physiology in Potsdam and the Max Planck Institute for Developmental Biology in Tübingen now report, the sugar molecule trehalose-6-phosphate (T6P) takes on a key role in monitoring energy reserves in thale cress, Arabidopsis thaliana, thereby controlling flowering time in relation to energy reserves.
