Total protein concentration and enzymatic activities of peroxidase and chitinase from the shoot and root tissues of control and chitosan-treated plants
| Plant tissue | Condition | Protein content (mg protein/g fresh weight) | Peroxidase activity (ΔOD/min·mg protein) | Chitinase activity (mmol GlcNAc released/g protein) |
|---|---|---|---|---|
| Shoot | Control | 13.62 ± 1.26 | 0.51 ± 0.12 | 0.21 ± 0.02 |
| Chitosan | 10.88 ± 2.96 | 0.66 ± 0.11 | 0.21 ± 0.04 | |
| Root | Control | 2.72 ± 0.33 | 13.17 ± 0.80 | 0.51 ± 0.20 |
| Chitosan | 1.27 ± 0.46 | 30.80 ± 8.06‡ | 0.85 ± 0.11 |
Values express mean ± SEM from three biological replicates.
