“…Thus, GB can provide protection from salt-induced cell death by decreasing the concentration of ROS accumulation and improving membrane integrity (Banu et al 2009). In the present study, the activity of antioxidant enzymes, including SOD, APX and CAT, was higher and the H 2 O 2 content was lower in GB-treated plants (Asada 1999;Kumar et al 2017). The H 2 O 2 content was correlated negatively with the activity of antioxidant enzymes.…”

Chilling injury is an important natural stress that can threaten cotton production, especially at the sowing and seedling stages in early spring. It is therefore important for cotton production to improve chilling tolerance at these stages. The current work examines the potential for glycine betaine (GB) treatment of seeds to increase the chilling tolerance of cotton at the seedling stage. Germination under cold stress was increased significantly by GB treatment. Under low temperature, the leaves of seedlings from treated seeds exhibited a higher net photosynthetic rate (PN), higher antioxidant enzyme activity including superoxide dismutase, ascorbate peroxidase and catalase, lower hydrogen peroxide (H2O2) content and less damage to the cell membrane. Enzyme activity was correlated negatively with H2O2 content and degree of damage to the cell membrane but correlated positively with GB content. The experimental results suggested that although GB was only used to treat cotton seed, the beneficial effect caused by the preliminary treatment of GB could play a significant role during germination that persisted to at least the four-leaf seedling stage. Therefore, it is crucial that this method is employed in agricultural production to improve chilling resistance in the seedling stage by soaking the seeds in GB.

“…Glycine betaine is a zwitterionic, quaternary ammonium compound which is a N-methylated derivative of glycine (Ashraf and Foolad 2007;Fariduddin et al 2013) and accumulates abundantly in many plant species, especially halophytes, under a range of environmental stresses (Pardo-Domènech et al 2016). Owing to its unique structure, GB tends to interact with both the hydrophilic and hydrophobic domains of plant cellular macromolecules such as enzymes and proteins (Ashraf and Foolad 2007;Kumar et al 2017). The intrinsic levels of GB are believed to be ontogenetically regulated because it is found in young tissues during continued stress, while its degradation does not significantly occur in plants.…”

“…Glycinebetaine, the most important organic osmolytes, show variation in their accumulation in diverse plant species due to the imposition of different environmental stresses such as salinity, drought, high temperatures, heavy metals, chilling, UV radiation, etc. [8,37,38]. It is involved in the protection of many plant species against a range of oxidative stress under stressful conditions, such as, salinity [39][40][41][42], drought [43][44][45][46], metal/metalloid stress [47][48][49], high temperature [45,50] and chilling [23,51,52].…”

In the era of climate change, abiotic stresses (e.g., salinity, drought, extreme temperature, flooding, metal/metalloid(s), UV radiation, ozone, etc.) are considered as one of the most complex environmental constraints that restricts crop production worldwide. Introduction of stress-tolerant crop cultivars is the most auspicious way of surviving this constraint, and to produce these types of tolerant crops. Several bioengineering mechanisms involved in stress signaling are being adopted in this regard. One example of this kind of manipulation is the osmotic adjustment. The quarternary ammonium compound glycinebetaine (GB), also originally referred to as betaine is a methylated glycine derivative. Among the betaines, GB is the most abundant one in plants, which is mostly produced in response to dehydration caused by different abiotic stresses like drought, salinity, and extreme temperature. Glycinebetaine helps in decreased accumulation and detoxification of ROS, thereby restoring photosynthesis and reducing oxidative stress. It takes part in stabilizing membranes and macromolecules. It is also involved in the stabilization and protection of photosynthetic components, such as ribulose-1, 5-bisphosphate carboxylase/oxygenase, photosystem II and quarternary enzyme and protein complex structures under environmental stresses. Glycinebetaine was found to perform in chaperone-induced protein disaggregation. In addition, GB can confer stress tolerance in very low concentrations, and it acts in activating defense responsive genes with stress protection. Recently, field application of GB has also shown protective effects against environmental adversities increasing crop yield and quality. In this review, we will focus on the role of GB in conferring abiotic stress tolerance and the possible ways to engineer GB biosynthesis in plants.
