“…Our previous work showed that neither the plant volatile chemotypes nor the metabotypes studied here were likely induced by aphid feeding (Clancy et al, 2018(Clancy et al, , 2016 and Host preference of aphids to different plant variants is known from various experimental studies .…”

“…The lack of association between plant metabotypes and aphid genotypes in the very first sampling period in 2015, but significant associations in all the later three periods, highlights the role of plant secondary metabolites on aphid performance, with high population growth rates leading to longer colony persistence (Senft et al, 2017), and stronger genotype-metabotype associations. We previously showed that aphids colonised "preferred" volatile chemotypes in the early part of the season (Clancy et al, 2016) and later on colonised almost all plants belonging to the "preferred" metabotypes irrespective of which volatile chemotypes they belonged (Clancy et al, 2018).…”

“…We used the plant volatile chemical information on 22 compounds, emitted from specialised storage structures on the plant (identified using GC-MS), from Clancy et al (2016), and secondary metabolite information of 1,020 mass features as identified using LC-MS by Clancy et al (2018) (for more details, see Appendix S1). Our focus was only on those plants that were colonised by aphids, so we performed new cluster analyses on these 87 plants to obtain chemotype and metabotype plant groupings, using the package "pvclust" (Suzuki & Shimodaira, 2015) in R v3.3.0 in RStudio v0.99.896.…”

“…These plants exhibit high variation in their volatile and non-volatile chemical compounds even within a single population (Clancy et al, 2018;Clancy, Zytynska, Senft, Weisser, & Schnitzler, 2016), and this can influence the associated invertebrate community structure (Balint et al, 2016;Kleine & Müller, 2011). In addition to variation in the VOCs, we showed-through untargeted metabolomic profiling of the leaves-that all plants of certain metabotypes (clusters of plants with similar metabolomic profiles) were colonised by aphids at the peak of the season (even on "less preferred" volatile chemotypes) (Clancy et al, 2018).

“…Based on the strong effects of both volatile and non-volatile chemical compounds in the plants on aphid-ant interactions in this system (Clancy et al, 2018(Clancy et al, , 2016Senft et al, 2019), we asked whether plant chemical variation could also lead to fine-scale structuring of the aphid population at the genetic level.

Plants exhibit impressive genetic and chemical diversity, not just between species but also within species, and the importance of plant intraspecific variation for structuring ecological communities is well known. When there is variation at the local population level, this can create a spatially heterogeneous habitat for specialised herbivores potentially leading to non‐random distribution of individuals across host plants. Plant variation can affect herbivores directly and indirectly via a third species, resulting in variable herbivore growth rates across different host plants. Herbivores also exhibit within‐species variation, with some genotypes better adapted to some plant variants than others. We genotyped aphids collected across 2 years from a field site containing ~200 patchily distributed host plants that exhibit high chemical diversity. The distribution of aphid genotypes, their ant mutualists, and other predators was assessed across the plants. We present evidence that the local distribution of aphid (Metopeurum fuscoviride) genotypes across host‐plant individuals is associated with variation in the plant volatiles (chemotypes) and non‐volatile metabolites (metabotypes) of their host plant tansy (Tanacetum vulgare). Furthermore, these interactions in the field were influenced by plant‐host preferences of aphid‐mutualist ants. Our results emphasise that plant intraspecific variation can structure ecological communities not only at the species level but also at the genetic level within species and that this effect can be enhanced through indirect interactions with a third species.

The environmental fluctuations of a constantly evolving world can mould a changing context, often unfavourable to sessile organisms that must adjust their resource allocation between both resistance or tolerance mechanisms and growth. Plants bear the fascinating ability to survive and thrive under extreme conditions, a capacity that has always attracted the curiosity of humans, who have discovered and improved species capable of meeting our physiological needs. In this context, plant research has produced a great wealth of knowledge on the responses of plants to a range of abiotic stresses, mostly considering model species and/or controlled conditions. However, there is still minimal comprehension of plant adaptations and acclimations to extreme environments, which cries out for future investigations. In this article, we examined the main advances in understanding the adapted traits fixed through evolution that allowed for plant resistance against abiotic stress in extreme natural ecosystems. Spatio‐temporal adaptations from extremophile plant species are described from morpho‐anatomical features to physiological function and metabolic pathways adjustments. Considering that metabolism is at the heart of plant adaptations, a focus is given to the study of primary and secondary metabolic adjustments as well as redox metabolism under extreme conditions. This article further casts a critical glance at the main successes in studying extreme environments and examines some of the challenges and opportunities this research offers, especially considering the possible interaction with ecology and metaphenomics.

Ecometabolomics of plant–herbivore and plant–fungi interactions: a synthesis study

The functional adaptive responses of higher plants to biotic interactions with herbivores and fungi have long been topics of research. One constraint to obtaining a comprehensive understanding of the most general plant responses, however, has been the difficulty of studying all plant functional shifts simultaneously due to analytical limitations. Now this is possible with the advent of metabolomics. Using 151 records from the WEB of SCIENCE database, we have analyzed the development and application of metabolomic profiles to ecological studies in the last two decades. We have used meta-analysis and pathway enrichment analyses to assess the whole set of constitutive and inducible defenses. Constitutive defenses against herbivores were mainly based on a significant high level of the metabolism of several amino acids with parallel increases in the concentrations of flavones (phenolics) and saponins (glycosides). Inducible defenses, though, were mainly based on the increases in concentration of methyl-ketone, pantothenate, and Coenzyme A. Butyrate metabolism and the mitochondrial electron-transport chain were upregulated, in agreement with previous reports that herbivory-activated plant chemical defenses were mainly based on jasmonic acid, salicylic acid, and ethylene-associated pathways. The metabolic responses/acclimations to pathogenic fungi were mainly linked with increases in aspartate and pyruvate metabolism, the transfer of acetyl groups within mitochondria, and the upregulation of branched-chain amino acids degradation pathways. These responses/acclimations were accompanied by higher concentrations of the most important groups of secondary metabolites such as phenolics (anthocyanins, flavonoids), quinones, alkaloids, terpenoids, and polyamines and other compounds related to antistress mechanisms such as proline. The leaves of mycorrhized plants accumulated nucleotide sugars, sphingolipids, and methylhistidine. These responses were associated with maintaining the integrity of plant cell membranes under fungal hypha penetration. The responses were accompanied by increases in the concentrations of phenolics, blumenols, and alkaloids and decreases in the concentrations of polyamines, consistent with the mycorrhizal inhibition of polyamines. This summary provides a clear synthesis of the most successful plant strategies selected after millions of years of evolution and will be a very promising tool for the management of crops and ecosystems and for selecting the main lines in breeding studies for future research.
