“…The GSH pools in the Arabidopsis atgstu17 mutant were 35% higher compared with wild-type plants (Jiang et al 2010). Application of exogenous betaine and proline application improved GSH level and maintained high activities of GST and Gly I, thereby protecting lentil plants from oxidative damage and toxic effects of MG (Molla et al 2014). Koffler et al (2014) demonstrated the signaling roles of GSH in Arabidopsis thaliana under drought stress.…”

Glutathione (GSH; c-glutamyl-cysteinyl-glycine) is a small intracellular thiol molecule which is considered as a strong non-enzymatic antioxidant. Glutathione regulates multiple metabolic functions; for example, it protects membranes by maintaining the reduced state of both a-tocopherol and zeaxanthin, it prevents the oxidative denaturation of proteins under stress conditions by protecting their thiol groups, and it serves as a substrate for both glutathione peroxidase and glutathione S-transferase. By acting as a precursor of phytochelatins, GSH helps in the chelating of toxic metals/metalloids which are then transported and sequestered in the vacuole. The glyoxalase pathway (consisting of glyoxalase I and glyoxalase II enzymes) for detoxification of methylglyoxal, a cytotoxic molecule, also requires GSH in the first reaction step. For these reasons, much attention has recently been directed to elucidation of the role of this molecule in conferring tolerance to abiotic stress. Recently, this molecule has drawn much attention because of its interaction with other signaling molecules and phytohormones. In this review, we have discussed the recent progress in GSH biosynthesis, metabolism and its role in abiotic stress tolerance.

A field experiment was conducted to investigate influence of exogenous application of glycine betaine (GB) on performance of wheat under prolonged drought conditions. A set of 19 wheat genotypes differing in stress sensitivity, were sprayed with 100mM GB at maximum tillering and anthesis stage. GB treatment significantly declined the phenological pace under drought stress by increasing days to anthesis. Foliar applied GB improved grains/spike and thousand grain weight of selected wheat genotypes over stressed ones. The genotype specific response to GB application suggested some threshold optimum level to be necessary for yield improvement under drought stress in susceptible genotypes as compared with tolerant ones. In overall, GB alleviated negative effects of drought stress by a rise in harvest index of most genotypes suggesting its role in assimilate translocation.

“…1 and 2). Exogenous application of GB enhanced tolerance to abiotic stresses in many plant species such as drought stress in wheat and lentil (Raza et al 2014;Molla et al 2014) and salinity stress in rice . Chen and Murata (2011) summarized that foliar applied GB is efficiently translocated from source to sink tissues via the phloem.…”

“…Glycinebetaine increased salt tolerance in rice seedlings by increasing the activities of antioxidant enzymes such as CAT and APX . Exogenous GB enhanced drought tolerance in wheat plants by improving transpiration rate and photosynthesis and uptake of nutrients (Raza et al 2014) and in Lentil decreased the oxidative stress by reducing H 2 O 2 levels (Molla et al 2014). Recently, GB application reduced Cd toxic effects in rice plants grown hydroponically by increasing growth and chlorophyll contents (Cao et al 2013).…”

Little information is available on the role of glycinebetaine (GB) in chromium (Cr) tolerance while Cr toxicity is widespread problem in crops grown on Cr-contaminated soils. In this study, we investigated the influence of GB on Cr tolerance in wheat (Triticum aestivum L.) grown in sand and soil mediums. Three concentrations of chromium (0, 0.25, and 0.5 mM) were tested with and without foliar application of GB (0.1 M). Chromium alone led to a significant growth inhibition and content of chlorophyll a, b, proteins and enhanced the activity of antioxidant enzymes. Glycinebetaine foliar application successfully alleviated the toxic effects of Cr on wheat plants and enhanced growth characteristics, biomass, proteins, and chlorophyll contents. Glycinebetaine also reduced Cr accumulation in wheat plants especially in grains and enhanced the activity of antioxidant enzymes in both shoots and roots. This study provides evidence that GB application contributes to decreased Cr concentrations in wheat plants and its importance in the detoxification of heavy metals.
