Functional categories of proteins with differential abundance in wheat root with PDS solution under salt stress. Four kinds of treatments, which were control, salt, PDS, and salt + PDS, were performed. Proteins extracted from wheat root after treatment were enriched, reduced, alkylated, and digested. After analysis by LC–MS/MS, the relative abundance of proteins from wheat was compared as follows: salt/control (A) (Table S3) and salt + PDS/salt (B) (Table S4). Functional categories of changed proteins were determined using gene-ontology analysis. Red and blue columns show increased and decreased proteins, respectively.
