SnRK1 connects photosynthesis and nitrate signalling

Cooperation between nitrogen assimilation and photosynthesis is central for plant growth and development in adaption to changing environmental conditions. This work reveals that the plant energy sensor SnRK1 represses nitrate signalling by phosphorylating NODULE INCEPTION PROTEIN-LIKE PROTEIN (NLP7) to promote its degradation in response to carbon deficiency or nitrate depletion.
