“…Those metabolic features present exclusively in one or a subset of the plant species contributed to specific responses, highlighting the need to take metabolic backgrounds of plant species into account in comparative environmental phytometabolome studies. Indeed, plant species have distinct metabolic phenotypes due to qualitative and quantitative differences in metabolites 7,[11][12][13] emerging from different evolutionary selection pressures and ecological niches occupied by the respective species. The high responsiveness of the Fabaceae M. truncatula may be attributed to its extraordinary high affinity to root symbionts, including AMF but also nodule-forming rhizobia 25 (not detected under our experimental conditions), somehow priming the plants to strongly respond to these endosymbionts.…”

High specificity in plant leaf metabolic responses to arbuscular mycorrhiza

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.

“…4,9,10 ) and the transferability of findings from these models to other plant systems is debatable. Since plant species 7,[11][12][13] and even conspecifics 14 differ in their metabolomes, metabolic prerequisites of species have to be taken into account to delineate common from species-specific changes in response to an identical challenge.…”

Metabolomics - Fundamentals and Applications

Metabolomics is a study through can be obtain a beter understanding of the complexity of the biological systems, through the chemical composition and relations with the physiology of the plant. The literature describes a lot of information on this support in areas of medicinal plants, chemosystematics, adulteration of plants, etc., but it is scarce in agriculture. At present, agriculture plays a crucial role in human beings. The demand of foods has increased due to the continuous increase in the population, and this requires an increase in the production of crops, besides the crops being afected by the climatic change, atack of pest and diseases and resistance to a conventional agrochemicals. At present, scientists are doing some practices or studies of genetic improvement of crops to increase their production and avoid the problems pointed out. It is an important part of the genomic studies; the results could be the basis for a genetic improvement based on the chemical composition of the crops, and in the metabolomics studies represent a crucial role in their quality for human consumption. The aim of the chapter is to review the literature from 10 years behind emphasizing the importance of metabolomics in crops of economic and feed value.

“…NMR is robust, highly reproducible, and requires minimal sample preparation which minimizes experimental artifacts and bias. Because of the desire for highest sensitivity, 1H NMR is the most common technique used and is combined with chemometric methods to profile, fingerprint or discriminate among crude herbal samples (Bailey et al, 2002;Zulak et al, 2008;Lee et al, 2009;Kim et al, 2010;Mahmud et al, 2014), and for quality control (Wang et al, 2004, Rasmussen et al, 2006, van der Kooy et al, 2008. 1H NMR measurements of herbal medicines have been reported using magnetic fields from 300 to 800 MHz (Zulak et al, 2008;Kim et al, 2011).…”

Chemical profiling and standardization of the defatted methanol extract of the leaves of Vitex negundo L. were carried out using 13C nuclear magnetic resonance (NMR) analysis followed by chemometric analysis of the chemical shift data. Chemical profile was obtained using a k-means cluster profile and chemical standardization which was achieved using a multivariate control chart. The V. negundo samples were made up of four groups: the training set, submitted samples from production farms, commercial samples, such as tablets, capsules and teas, and experimental samples (samples which were allowed to degrade). Four groups were generated in k-means cluster, which generally corresponded to the four types of samples. The multivariate control chart identified samples whose quality exceeded the upper control limit, all of which were commercial samples and experimental samples. The samples were also analyzed by quantitative thin layer chromatography (qTLC) using agnuside as marker compound. Comparison of the qTLC results with the k-means cluster and the multivariate control chart showed poor correspondence. This means that a univariate analysis of a plant sample using a marker compound is useful only for quantification of the target compound. On the other hand, chemical profiling and standardization of medicinal plants should use a multivariate method.
