Figure 1. Characterization of the phosphoproteome profile in Arabidopsis roots in response to nitrate.

Figure 1

Venn diagrams show the overlap of transient (5 min) and more persistent (20 min) changes in phosphoprotein relative abundance after 5 mM nitrate treatments compared with each control condition (5 mM KCl) in Arabidopsis roots.

  1. Overlap of phosphoproteins that were “up‐regulated” by nitrate at 5 min (dark yellow) and 20 min (light yellow)
  2. Overlap of phosphoproteins that were “down‐regulated” by nitrate at 5 min (blue) and 20 min (light blue).
  3. Identification of common phosphoproteins with published phosphoproteome datasets in response to nitrate deprivation (Menz et al, 2016; Wu et al, 2017) or nitrate resupply (Engelsberger & Schulze, 2012). In the Sungear figure, vertices represent the different phosphoprotein sets identified in different studies. The circles with arrows within the square represent different intersections among the phosphoprotein studies and the size is proportional to the number of proteins in that circle. The position and the arrows of the circle indicated which vertices or data sets the proteins belong to. The largest circles on the perimeter indicate most of the phosphoprotein are associated with only one experiment.
