Other claims from this paper (11)
- Intervention effect GABA inhibited cadmium transport from roots to leaves under cadmium stress.
- Intervention effect Exogenous GABA reduced malondialdehyde content under cadmium stress.
- Intervention effect GABA alleviated cell membrane lipid peroxidation under cadmium stress.
- Observation POD activity responded on days 3 and 7 of stress.
- Observation CAT activity changes concentrated on days 11 and 15.
- Observation Root APX was active throughout the stress period.
- Association Factorial analysis linked the antioxidant pathway strongly to survival and growth under GABA and stress.
- Intervention effect Exogenous GABA activated the GABA shunt, with a higher contribution in leaves.
- Mechanism GABA shunt activation induced changes in glutamate content.
- Observation Plants maintained higher endogenous GABA content and signal.
- Mechanism The authors link elevated GABA signalling to antioxidant regulation, lower membrane damage, and improved cadmium tolerance.
