Figure 4From: Proteome analysis of soybean leaves, hypocotyls and roots under salt stress Protein expression patterns in the root of soybeans treated with NaCl. Seeds were sown and treated with 40 mM NaCl. After 7 days, proteins were extracted from the root separated by 2-DE, and visualized by CBB staining. The pI and Mr of each protein were determined using 2-DE markers (Bio-Rad). Arrows indicate protein changes due to NaCl treatment, and circles mark the position of the same proteins from the control. Upward arrows indicate up-regulation and downward arrows indicate down-regulation.Back to article page
