Other claims from this paper (12)
- Intervention effect AtPgb1 overexpression alleviated PEG-induced growth retardation.
- Intervention effect AtPgb1 overexpression reduced programmed cell death under PEG stress.
- Observation AtPgb1 down-regulated roots had extensive programmed cell death under PEG stress.
- Observation AtPgb1 down-regulated roots had reduced expression of ER-stress attenuators including BI-1.
- Mechanism ROS and ethylene mediated cell death in stressed roots with AtPgb1 suppression.
- Intervention effect Suppressing ROS synthesis or ethylene perception reduced cell death.
- Intervention effect Suppressing ROS synthesis or ethylene perception partly restored root growth.
- Observation PEG-induced root growth cessation followed loss of cell and tissue specification in the meristem.
- Observation AtPgb1 overexpression attenuated, and suppression aggravated, root meristem changes.
- Intervention effect AtPgb1 suppression compromised quiescent cell function.
- Intervention effect AtPgb1 suppression rapidly reduced meristem size.
- Observation SCR and WER expression and localization were most affected in PEG-treated roots with suppressed AtPgb1.
