Other claims from this paper (11)
- Intervention effect Drought stress significantly decreased wheat root tip number.
- Intervention effect ABA application significantly increased wheat root tip number under PEG-induced dehydration.
- Intervention effect H2O2 application markedly reduced wheat root tip number under PEG-induced dehydration.
- Intervention effect Drought stress increased DHA, GSH and GSSG levels in wheat.
- Intervention effect Drought stress decreased AsA levels, AsA/DHA and GSH/GSSG ratios in wheat.
- Intervention effect Drought stress markedly increased GR, APX, MDHAR and DHAR enzyme activities.
- Intervention effect ABA inhibitor significantly inhibited GR, DHAR and APX activities.
- Intervention effect H2O2 inhibitor significantly inhibited DHAR and MDHAR activities.
- Intervention effect ABA inhibitor significantly promoted H2O2 increases under PEG treatment.
- Intervention effect H2O2 inhibitor significantly blocked ABA increases under PEG treatment.
- Mechanism The authors infer that ABA and H2O2 probably interact during wheat drought stress to modulate AsA–GSH cycle enzymes.
