Characteristics of the proteome of bast barks in ramie. a Subcellular localizations of all 6971 identified proteins based on the prediction by Gene Ontology (GO) annotation. Numbers in the graph represent the number of proteins located in the corresponding organelle. The secondary MS/MS spectra of whole_GLEAN_10022020 (b) and whole_GLEAN_10024940 (c) were quantified in the bark from the top and middle part of the stem, where the fibers do not initiate growth or are growing, respectively. The x and y axis in the figure of (b) and (c) indicated the mass-to-charge ratio (m/z) and the relative abundance of peptide, respectively. d GO enrichment analyses. GO terms were significantly enriched for the following three GO categories: biological process, cellular component, and molecular function. Each circle stands for a GO term. Within the Cartesian coordinates (x, y), the closer the circles, the more the GO terms are related. The measurement of the circles is relative to the number of related GO terms. The numbers in the circles show the counts of differentially expressed proteins in the GO terms. The color of the circle represents the significance of the enrichment (P < 0.01)
