Predicted mycorrhizal sensor complexes. Connected subnetworks are hypothesized to be sensor complexes expressed in aspen root during mycorrhizal interaction, connecting extracellular sensory receptors to transcription factors via signal cascades. Diamonds indicate a transcription factor, triangles indicate a transmembrane receptor, circles indicate a signal cascade protein, and octagons indicate a pathogen defense response protein. Edges indicate a predicted physical interaction between expressed proteins. Nodes highlighted with color are gene models that overlap gene co-expression clusters (highlighting color uses same scheme as in Figure 3). (A–D) refer to predicted Protein Sensor Complexes A–D described in text. The complete set of predicted complexes is available in Table S6.
