Plant Growth-Promoting Rhizobacteria Enhance Salinity Stress Tolerance in Okra through ROS-Scavenging Enzymes

Figure 4

Effect of PGPR inoculation on DHAR, GR, APX, and CAT transcript levels by semiquantitative RT-PCR analysis of okra leaves under salt stress. T0: noninoculated salt treated plants, T1: UPMR2 inoculated salt treated plants, T2: UPMR18 inoculated salt treated plants, and T3: both UPMR2 and UPMR18 inoculated salt treated plants. Actin: positive control, APX: ascorbate peroxidase, CAT: catalase, GR: glutathione reductase, and DHAR: dehydroascorbate reductase.
