Abstract Phytochemical diversity is comprised of two main dimensions—the average (alpha) within‐plant neighbors or the difference (beta) in composition chemicals between plant neighbors. Research, however, has primarily examined consequences phytochemical on herbivore performance through a single dimension, even though multidimensional. Furthermore, ecological role not well understood because each these dimensions exhibits unique biological effects performance. Therefore, it been difficult to tease apart relative importance alpha and beta chemical diversities plant–herbivore interactions.

Research on the ecological and evolutionary roles of phytochemicals has recently progressed from studying single compounds to examining chemical diversity itself. A key conceptual advance enabling this progression is use species metrics for quantifying phytochemical diversity. In perspective, we extend theory developed further our understanding what exactly how its many dimensions impact processes.

However, analytical constraints the lack untargeted processing workflows have precluded comprehensive metabolite profiling and, consequently, collection critical currencies test theory predictions for functions plant metabolic diversity.

Classic theory relates herbivore pressure to the ecology and evolution of plant defenses. Here, we summarize current trends in study plant–herbivore interactions how they shape chemical defenses, host choice, community composition diversity. Inter- intraspecific variation defense investment is driven by resource availability. The defenses at deeper nodes phylogeny conserved, yet are highly labile tips. On an ecological timescale, while greater specialization tropical herbivores enhances local diversity reducing performance plants with similar temperate ecosystems more generalist herbivores, rare profiles a disadvantage. evolutionary choice largely determined rather than phylogeny, leading tracking cocladogenesis. interplay between shapes both origin maintenance

Plants harbour a great chemodiversity, that is diversity of specialised metabolites (SMs), at different scales. For instance, individuals can produce large number SMs, and populations differ in their metabolite composition. Given the ecological economic importance plant it important to understand how arises maintained over evolutionary time. other dimensions biodiversity, species genetic diversity, quantitative models play an role addressing such questions. Here, we provide synthesis existing hypotheses models, mathematical computer simulations, for evolution chemodiversity. We describe each model's ingredients, biological processes shape scales considers whether has been formalized as model. Although identify several not all are dynamic many influential have remained verbal. To fill these gaps, outline our vision future chemodiversity modelling. used variation may be adapted present flexible framework creation individual-based address combine ingredients bring this about.

Plant functional traits provide a valuable tool to improve our understanding of ecological processes at range scales. Previous handbooks on plant have highlighted the importance standardising measurements and evolutionary processes.

Summary Plants produce large numbers of phytochemical compounds affecting plant physiology and interactions with their biotic abiotic environment. Recently, chemodiversity has attracted considerable attention as an ecologically evolutionary meaningful way to characterize the phenotype a mixture compounds. Currently used measures diversity, related dissimilarity, generally do not take structural or biosynthetic properties into account. Such can be indicative compounds' function inform about (in)dependence, should therefore included in calculations these measures.

Plant specialized metabolites (PSMs) are variably distributed across taxa, tissues, and ecological contexts; this variability has inspired many theories about PSM function, which, to date, remain poorly tested because predictions have outpaced the available data. Advances in mass spectrometry–based metabolomics enabled unbiased profiling, molecular biology techniques produced PSM-free plants; combination of these methods accelerated our understanding complex roles that PSMs play plants. Synthetic workflows producing high-value, structurally quantities purities sufficient for both medicinal functional studies. These enable reengineering transport, externalization, structural diversity, production novel facilitating rigorous tests long-standing theoretical why plants produce so different particular tissues contexts.
