The target of rapamycin (TOR) kinase is a conserved regulatory hub that translates environmental and nutritional information into permissive or restrictive growth decisions. Despite the increased appreciation of the essential role of the TOR complex in plants, no large-scale phosphoproteomics or interactomics studies have been performed to map TOR signaling events in plants. To fill this gap, we combined a systematic phosphoproteomics screen with a targeted protein complex analysis in the model plant Arabidopsis thaliana. Integration of the phosphoproteome and protein complex data on the one hand shows that both methods reveal complementary subspaces of the plant TOR signaling network, enabling proteome-wide discovery of both up- and downstream network components. On the other hand, the overlap between both datasets reveals a set of candidate direct TOR substrates. The integrated network embeds both evolutionarily conserved as well as plant-specific TOR signaling components, uncovering an intriguing complex interplay with protein synthesis. Overall, the network provides a rich dataset to start address fundamental questions how TOR controls key processes in plants such as autophagy, auxin signaling, chloroplast development, lipid metabolism, nucleotide biosynthesis, protein translation or senescence.
