γ-Aminobutyric acid treatment induced chilling tolerance in postharvest peach fruit by upregulating ascorbic acid and glutathione contents at the molecular level

“…It plays a crucial role in regulating pH in the cytosol, controlling carbon and nitrogen metabolism, and protecting cells from biotic and abiotic stresses (Hijaz et al, 2018). In recent years, there have also been many related researches on GABA-inducing chilling tolerance in post-harvest in fruit and vegetables (Ali et al, 2022;Fan et al, 2022;Jiao, 2022). Same as our previous studies (Yang et al, 2011), here we also found GABA could effectively reduce chilling incidence and maintain fruit quality during postharvest storage.…”

γ-Aminobutyric acid is involved in overlapping pathways against chilling injury by modulating glutamate decarboxylase and defense responses in papaya fruit

“…Papaya fruit improves low-temperature tolerance by enhancing the activities of energy metabolism-related enzymes like GAD (Pan et al, 2019). The GAD enzyme was increased in peach and banana fruits by improving the endogenous GABA content (Shang et al, 2011;Ali et al, 2022). Aghdam et al (2016) reported that the GABA shunt pathway might be a potent mechanism for enhancing chilling tolerance in fresh produce.…”

Editorial: Recent advances and approaches in the application of elicitors to enhance resistance mechanisms in fresh produce

“…Elicitors play a role in a number of defensive processes, including the regulation of enzyme activity, cellular defense against oxidative damage, and abiotic stress tolerance. Fresh produce kept at low temperature was protected from abiotic stressors by exogenous application of γ-aminobutyric acid (Ali et al, 2022). Similarly, hydrogen peroxide (Duarte-Sierra et al) and nitric oxide (Khaliq et al, 2021) delayed ripening and enhanced resistance of broccoli and custard apple fruits, respectively.…”

“…Pre and post-harvest abiotic stresses are the main causes affecting quality and production of fresh produce worldwide (Suwannachot et al). These abiotic stresses may result in a number of physiological, morphological, biochemical and molecular alterations that have a negative impact on plant growth, productivity, and quality characteristics (Ali et al, 2022). Abiotic stresses also affect the shelf-life, quality and nutritional properties, and these alterations can result in significant economic losses for producers, storage operators and retailers.…”
