Other claims from this paper (11)
- Intervention effect GABA treatment increased endogenous GABA during heat stress.
- Intervention effect GABA alleviated heat-related growth inhibition and water loss.
- Intervention effect GABA-treated plants had lower carbonyl content, malondialdehyde content and electrolyte leakage than untreated plants under heat stress.
- Intervention effect GABA-treated plants had higher antioxidant capacity and enzyme activities than untreated plants under heat stress.
- Intervention effect Heat stress decreased chlorophyll content, stomatal conductance and transpiration rate.
- Intervention effect Heat stress decreased net photosynthesis and water use efficiency.
- Intervention effect GABA alleviated heat-induced declines in chlorophyll content, gas exchange and water use efficiency.
- Intervention effect GABA further increased heat-induced HSP and HSF expression.
- Mechanism The authors attribute reduced oxidative damage and chlorophyll loss to enhanced antioxidant capacity under GABA.
- Mechanism The authors link higher leaf photosynthesis under GABA to higher water soluble carbohydrate accumulation.
- Mechanism The authors suggest GABA thermotolerance may involve HSF pathway upregulation.
