“…Plants being sessile in nature, have to simultaneously or sequentially endure changing environments including various prevalent abiotic stresses. These abiotic stresses include temperature extremes, high light intensity, salinity, water scarcity, flooding and nutrient deficiency/excess that individually or in combination pose negative effects on plant growth, development and productivity (Dutta et al 2018;Khan et al 2019). It is estimated that global yield reductions to abiotic stress approach 70 percent (Acquaah 2009).…”

“…Glycine betaine, an amino acid derivate from sugar beet (Beta Vulgaris L. v. altissima), is purified, enriched and crystallised (Makela et al, 1998;Rajashekar et al, 1999). The known role of GB is maintaining water content in plant cells by lowering solute potential under osmotic stress in osmotic adjustment (Makela, 2004;Dutta et al, 2018). Both the exogenous application of GB and the genetically engineered biosynthesis of GB in such crops is a promising strategy to increase stress tolerance (Wani et al, 2013).…”

Glycine betaine (GB) is a quaternary ammonium compound that can be found in a wide range of bacterial, plant and animal species. The exogenous application of GB is a convenient method for the induction of crop tolerance to various abiotic stresses. We examined the effects of different exogenous GB concentrations to deficit irrigation conditions (15% drainage) under soilless condition in terms of morpho-physiological, yield, quality and biochemical features. The different GB concentrations (0, 10 and 20 mM) were used in Fortuna and Albion strawberry cultivars. As a result of the research, GB treatments increased plant growth and yield under deficit irrigation conditions. Fruit weight inclined by 26.29-49.50% and fruit yield by 17.17-39.59% at GB treatments as compared to control. Regarding biochemical content, increasing GB concentrations from 0 mM to 20 mM caused total anthocyanin to decrease, whereas the ascorbic acid increased. Furthermore, the highest yield, fruit firmness, chroma and total anthocyanin were determined in the Fortuna; the highest total soluble solid and ascorbic acid content in the Albion cultivar. Our results showed that the increase in yield and quality was due to exogenous GB applications. Indeed, water stress tolerance varied depending on cultivars.

“…A higher concentration of glycine betaine and proline generally reflects adaptation strategies for particular environmental conditions [32]. Glycine betaine and proline are the two major organic osmolytes accumulated in several plants in response to environmental stresses such as drought, salinity, extreme temperatures, UV radiation and heavy metals [33,34]. Moreover, the increased concentration of sucrose and glucose might reflect an increased photosynthetic activity of the plants growing at the lowest altitude or, instead, a temporary way to save energy by reducing carbohydrate consumption under drought stress, when stomatal conductance and photosynthetic activity are reduced to limit evapotranspiration.…”

Metabolomic Study of Dactylis glomerata Growing on Aeolian Archipelago (Italy)

et al. 2022

The Aeolian Islands (Italy) are a volcanic archipelago in the Tyrrhenian Sea comprising seven main islands, among which are two active volcanoes. The peculiar geological features and the wide variety of environments and soils have an important impact on native plants, and in particular, the Aeolian populations of Dactylis glomerata (a perennial cool-season bunchgrass) exhibit remarkable phenotypic variability. Considering that environmental drivers also strongly affect the production of plant metabolites, this work aimed at comparing the metabolomic profiles of D. glomerata (leaves) harvested at different altitudes on four islands of the Aeolian archipelago, namely: Lipari, Vulcano, Stromboli and Panarea. Samples were analyzed by 1H NMR profiling, and data were treated by PCA. Samples collected on Stromboli were very different from each other and from the samples collected in the other islands. Through an OPLS model, using altitude as the y variable, it emerged that the concentration of proline, glycine betaine, sucrose, glucose and chlorogenic acid of D. glomerata growing on Stromboli decreased at increasing altitude. Conversely, increasing altitude was associated with an increment in valine, asparagine, fumaric acid and phenylalanine.
