“…Instead, most studies assess plastic or evolutionary responses to environmental stressors by manipulating abiotic variables in controlled environments (Sardans et al 2011;Colinet et al 2012;Padfield et al 2016). Notable exceptions are the studies on Arabidopsis lyrata that demonstrated distinct metabolic phenotypes along the species' latitudinal distribution, with a typical coldinduced metabolome in the north, indicating adaptation to the local climate (Davey et al 2008), but no difference in metabolic fingerprint between large connected versus marginal fragmented populations (Kunin et al 2009).…”

Despite an increasing number of studies documenting life-history evolution during range expansions or shifts, we lack a mechanistic understanding of the underlying physiological processes. In this explorative study, we used a metabolomics approach to study physiological changes associated with the recent range expansion of the two-spotted spider mite (Tetranychus urticae). Mite populations were sampled along a latitudinal gradient from range core to edge and reared under benign common garden conditions for two generations. Using gas chromatography-mass spectrometry, we obtained metabolic population profiles, which showed a gradual differentiation along the latitudinal gradient, indicating (epi)genetic changes in the metabolome in association with range expansion. These changes seemed not related with shifts in the mites' energetic metabolism, but rather with differential use of amino acids. Particularly, more dispersive northern populations showed lowered concentrations of several essential and nonessential amino acids, suggesting a potential downregulation of metabolic pathways associated with protein synthesis.

“…Unfavorable environmental factors such as drought, salinity, chilling, freezing, high temperature etc. significantly limit productivity and quality of crop species worldwide and in extreme cases cause the plant to die (Sardans et al, 2011). Almost all of abiotic stresses are often interconnected and associated with plant-water relations.…”

CitationDawood MG. 2016. Influence of osmoregulators on plant tolerance to water stress, 13 (1), 42-58. Retrieved from www.pscipub.com (DOI: 10.15192/PSCP. SA.2016.13.1.4258) This article highlights on some recent researches, which studied the impact of osmoregulator compounds and their application on the plant in order to increase the plant tolerance to water stress. Water stress limits the growth, productivity and quality of agricultural crops in the world. Water Stress is not only due to the scarcity of water but also due other factors such as salinity, high temperatures and severe cold that make plants not able to absorb enough water from soil to grow well and this is called physiological drought that leads to a series of disorders in physiological and biochemical processes mainly due to lack of osmotic (internal water content of the plant deficiency), and the toxicity of salt ions. One way to overcome the negative impact of water stress on plants is the use of osmoregulators compounds formed by the plant when exposed to stress such as glycinebetaine, proline and trehalose. Osmoregulator compounds mainly regulate osmotic pressure within the plant to be able to absorb water and also have influential and effective roles on a lot of vital processes in the plant. they protect membranes of chloroplasts and thus increase the photosynthesis efficiency and have the ability to protect cell walls and membranes, which leads to stability and the organization of permeability and play an important role in scavenging the free radicals thus lead to mitigate the adverse impact of stress and improve growth, productivity and quality of plants. It can be concluded from this article that the best material used to increase plant tolerance to water stress is glycinebetaine where it can be obtained in large quantities and at low prices, making use it appropriately in economic terms as well as effective impact on increasing the tolerance of plants to water stress and reflected in increasing crop quantity and quality. Moreover, the use of proline has also an influential and effective role in increasing plant tolerance to water stress, but more expensive than glycinebetaine. Trehalose is an efficient protectant against water deficit conditions, and it is also effective in reducing oxidative stress but trehalose considered the most expensive, until now. We must intensify efforts to study and understand more of the physiological and biochemical changes played by these substances within the plant under stress conditions to improve plant productivity under water stress with modest economic cost.

High specificity in plant leaf metabolic responses to arbuscular mycorrhiza

et al. 2014

The chemical composition of plants (phytometabolome) is dynamic and modified by environmental factors. Understanding its modulation allows to improve crop quality and decode mechanisms underlying plant-pest interactions. Many studies that investigate metabolic responses to the environment focus on single model species and/or few target metabolites. However, comparative studies using environmental metabolomics are needed to evaluate commonalities of chemical responses to certain challenges. We assessed the specificity of foliar metabolic responses of five plant species to the widespread, ancient symbiosis with a generalist arbuscular mycorrhizal fungus. Here we show that plant species share a large 'core metabolome' but nevertheless the phytometabolomes are modulated highly species/taxon-specifically. Such a low conservation of responses across species highlights the importance to consider plant metabolic prerequisites and the long time of specific plant-fungus coevolution. Thus, the transferability of findings regarding phytometabolome modulation by an identical AM symbiont is severely limited even between closely related species.
