Figure 4: Interaction networks of the diurnal phosphoproteome at
the D-L and L-D transitions.
An association network analysis of statistically significant diurnally
changing phosphorylated proteins was performed using the STRING-DB
(ANOVA P value ≤ 0.05). Edge thickness indicates strength of the
connection between two nodes (0.5 - 1.0). Phosphorylated proteins (grey
circles) are labeled by either their primary gene annotation or
Arabidopsis gene identifier (AGI). Outer circle around each node depicts
the standardized relative log2 FC in phosphorylation status of this
protein between time-points. The sliding scale of yellow to blue
represents a relative increase and decrease in phosphorylation,
respectively. The inner colored circles represent in silicopredicted subcellular localization (SUBAcon;
suba3.plantenergy.uwa.edu.au). Nucleus (red), cytosol (orange), plastid
(green), mitochondria (blue), plasma membrane (purple), peroxisome
(dark yellow), endoplasmic reticulum/golgi/secreted (black) are
depicted. A second shell of 5 STING-DB proteins (white circles) not
found in our dataset was used to highlight the interconnectedness of the
network. Multiple nodes encompassed by a labelled grey circle represent
proteins involved in the same cellular process.
