[Display omitted] •CB-61, 4′-OH-CB-61 and 4′-MeO-CB-61 led to growth inhibition and oxidative stress in rice.•The phytotoxicity of 4′-OH-CB-61 and 4′-MeO-CB-61 were greater than the parent PCB.•4′-MeO-CB-61 promoted saccharides catabolism, indicating greater energy demand.•CB-61 and 4′-OH-CB-61 prom...
