“…6,7 , Medicago truncatula 8 , Plantago spec. 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.…”

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.

“…Phenological stage, which has been well documented to influence specialized metabolites in model Plantago species (i.e., Barton, 2008; Hanley et al., 2013; Pankoke et al., 2013; Sutter & Muller, 2011), was not found to be an important factor in explaining metabolic variation in situ . Any differences due to phenological stage, were explained by differences in geographic region, which is a particularly important finding considering the difficultly in standardizing phenological stage when sampling plants growing in situ across great geographic distances.…”

“…Methanolic extractions are effective in extracting the specialized metabolites such as iridoid glycosides, caffeoyl phenylethanoid glycosides, and other nonvolatile, polar metabolites (Pankoke et al., 2013; Rønsted, Göbel, Franzyk, Jensen, & Olsen, 2000; Rønsted et al., 2003).

“…Due to these species’ widespread and nearly global distributions in nature, their medicinal value (Samuelsen, 2000), and because both can be easily grown under controlled conditions, P. lanceolata and P. major L. serve as excellent model organisms to explore biochemical responses and improve understanding of local adaptation (Fuchs & Bowers, 2004; Pankoke, Buschmann, & Mueller, 2013; Sutter & Muller, 2011). …”

“…When investigating the complex and often interrelated effects that environmental factors have on plant metabolic phenotypes, it is becoming increasingly popular to use untargeted metabolomic approaches, as fewer a priori assumptions are made, allowing for the detection of metabolic responses that were overlooked using targeted approaches (Pankoke et al., 2013; Schweiger et al., 2014; Sedio, Rojas Echeverri, Boya, & Wright, 2017; Sutter & Muller, 2011). Despite the extensive chemical ecology literature that exists for Plantago , still little is understood about metabolome‐wide responses (but see Sutter & Muller, 2011; Pankoke et al., 2013, 2015; and Schweiger et al., 2014).…”

Plants produce a multitude of metabolites that contribute to their fitness and survival and play a role in local adaptation to environmental conditions. The effects of environmental variation are particularly well studied within the genus Plantago; however, previous studies have largely focused on targeting specific metabolites. Studies exploring metabolome‐wide changes are lacking, and the effects of natural environmental variation and herbivory on the metabolomes of plants growing in situ remain unknown. An untargeted metabolomic approach using ultra‐high‐performance liquid chromatography–mass spectrometry, coupled with variation partitioning, general linear mixed modeling, and network analysis was used to detect differences in metabolic phenotypes of Plantago major in fifteen natural populations across Denmark. Geographic region, distance, habitat type, phenological stage, soil parameters, light levels, and leaf area were investigated for their relative contributions to explaining differences in foliar metabolomes. Herbivory effects were further investigated by comparing metabolomes from damaged and undamaged leaves from each plant. Geographic region explained the greatest number of significant metabolic differences. Soil pH had the second largest effect, followed by habitat and leaf area, while phenological stage had no effect. No evidence of the induction of metabolic features was found between leaves damaged by herbivores compared to undamaged leaves on the same plant. Differences in metabolic phenotypes explained by geographic factors are attributed to genotypic variation and/or unmeasured environmental factors that differ at the regional level in Denmark. A small number of specialized features in the metabolome may be involved in facilitating the success of a widespread species such as Plantago major into such wide range of environmental conditions, although overall resilience in the metabolome was found in response to environmental parameters tested. Untargeted metabolomic approaches have great potential to improve our understanding of how specialized plant metabolites respond to environmental change and assist in adaptation to local conditions.

Along ecological gradients, phenotypic differentiation can arise through natural selection on trait diversity and magnitude, and environment‐driven plastic changes. The magnitude of ecotypic differentiation versus phenotypic plasticity can vary depending on the traits under study. Using reciprocal transplant‐common gardens along steep elevation gradients, we evaluated patterns of ecotypic differentiation and phenotypic plasticity of several growth and defense‐related traits for two coexisting but unrelated plant species, Cardamine pratensis and Plantago major . For both species, we observed ecotypic differentiation accompanied by plasticity in growth‐related traits. Plants grew faster and produced more biomass when placed at low elevation. In contrast, we observed fixed ecotypic differentiation for defense and resistance traits. Generally, low‐elevation ecotypes produced higher chemical defenses regardless of the growing elevation. Yet, some plasticity was observed for specific compounds, such as indole glucosinolates. The results of this study may suggest that ecotypic differentiation in defense traits is maintained by costs of chemical defense production, while plasticity in growth traits is regulated by temperature‐driven growth response maximization.
