Functional groups in significantly regulated phosphoproteins. a Distribution of all quantified phosphopeptides in BR treatment and BR-responsive sites which has two-fold phosphorylation change. b The proteins with BR-responsive sites are annotated according to cellular compartment GO terms. The P-value is obtained from Fisher’s exact test with Benjamini-Hochberg correction. The red dash line denotes the P-value = 0.05. c The heatmap presents the dynamic change of biological process with similar analysis as in (b). The values in the heatmap represent the z-transformation of –log₁₀ (P-value) by GO term (Color scales: red, high overrepresentation; blue, high underrepresentation). The unique GO terms are lighted in dark blue
