Effect of PGPR [Pseudomonas aeruginosa (M1) & Burkholderia gladioli (M2)] and earthworms [Eisenia fetida (E)] on the gene expression of (A) SOD, (B) POD, (C) CAT, (D) APOX, (E) DHAR, (F) GR, (G) GST, and (H) RBOH in 10-day-old B. juncea seedlings, under chromium (Cr) stress. Data are presented as means of 3 independent replicates ± S.E (standard error). Different letters on the bar graphs indicate that mean values of the treatments are significantly different at p ≤ 0.05 (Tukey’s test).
