Characteristics of the phosphoproteomes of ramie bast barks. a Subcellular localizations of all 3,506 detected phosphoproteins based on GO annotation predictions. The numbers in the graph represent the number of proteins located in the corresponding organelles. b Proportion of single and multiple phosphorylation sites per protein in the phosphoproteome. c Number of differentially phosphorylated sites and proteins identified in the phosphoproteome of barks from the middle section of stems (MPS), compared with those in the top section of stems (TPS). d The secondary MS/MS spectra of the 210th pSer site of whole_GLEAN_10023180 in the TPS and MPS barks. e GO terms enriched with proteins with down-regulated phosphorylation levels in MPS bark. GO terms significantly enriched for the three GO categories, Biological process, Cellular component, and Molecular function. The color of the circle represents the significance of the enrichment (P < 0.01)
