Figure 6. Visualization of protein-protein interaction (PPI) network of differentially abundant proteins in Puccinellia tenuiflora roots using STRING analysis (confidence mode).

A total of 53 differentially abundant proteins represented by homologous proteins from Arabidopsis are shown in PPI network. The nodes represent proteins, and different protein groups are indicated in different colors. The lines represent the predicted functional associations. Strong associations are represented by thicker lines. Detailed information on protein names and abbreviations can be found in Table 1.
