Characteristics of higher plant terpenoids that result in mediation of numerous kinds of ecological interactions are discussed as a framework for this Symposium on Chemical Ecology of Terpenoids. However, the role of terpenoid mixtures, either constitutive or induced, their intraspecific qualitative and quantitative compositional variation, and their dosage-dependent effects are emphasized in subsequent discussions. It is suggested that little previous attention to these characteristics may… Expand
Plant volatiles as key players in diverse ecological interactions
TLDR
The co‐evolutionary theory suggests that the evolution of plant defense chemicals and the stepwise evolutionary responses to these chemicals by insects have led to the species diversity of both groups. Expand
Plant Defense Against Herbivores : Chemical Aspects
Plants have evolved a plethora of different chemical defenses covering nearly all classes of (secondary) metabolites that represent a major barrier to herbivory: Some are constitutive; others areExpand
Plant defense against herbivores: chemical aspects.
TLDR
Recognizing the herbivore challenge and precise timing of plant activities as well as the adaptive modulation of the plants' metabolism is important so that metabolites and energy may be efficiently allocated to defensive activities. Expand
Arbuscular mycorrhizal fungi: effects on plant terpenoid accumulation.
TLDR
A critical assessment and discussion of the literature relating to mechanisms by which AMF influence plant terpenoid accumulation, and whether this symbiosis can be harnessed in horticultural ecosystems was performed, identified modification of plant morphology, phosphorus availability and gene transcription involved with ter penoid biosynthetic pathways as key mechanisms associated with terpenoids accumulation in AMF-colonised plants. Expand
Impacts of interactions with soil organisms on the metabolome of ragwort (Senecio jacobaea L.)
TLDR
The findings of both experimental studies detected unexpected and previously unreported changes in plant metabolism, highlighting the importance of an untargeted approach when examining the chemical ecology of plant interactions. Expand
Terpenoids in plant and arbuscular mycorrhiza‐reinforced defence against herbivorous insects
TLDR
Improved understanding of the roles of terpenoids in plant and AM defences against herbivory and of interplant signalling in natural communities has significant implications for sustainable management of pests in agricultural ecosystems. Expand
Constitutive Secondary Plant Metabolites and Soil Fungi: Defense Against or Facilitation of Diversity
TLDR
The congruence of apparent accumulation of secondary metabolites in those organisms lacking an immune system, such as plants, fungi, or invertebrates, additionally supports the notion that the main function of these originally classified as waste products metabolites is defense against pathogens and predators. Expand
Terpenoid Secondary Metabolites in Bryophytes: Chemical Diversity, Biosynthesis and Biological Functions
TLDR
Current knowledge of terpenoid secondary metabolites, which constitute the largest family of plant metabolites, in bryophytes is reviewed from three perspectives: chemical diversity, biosynthesis, and biological functions. Expand
The Impact of Induced Plant Volatiles on Plant-Arthropod Interactions
TLDR
The different approaches that have been undertaken to manipulate indirect defenses, either via application of synthetic volatiles or via transgenic manipulation of plant-volatile production, to control the movements of foraging arthropods to improve biological control are summarized. Expand
Intraspecific plant chemical diversity and its relation to herbivory
TLDR
The existing chemotypical pattern of T. vulgare plants leads to a species-specific distribution of herbivores but may in turn be the result of contrasting selection pressures of various specialist and generalist herbivore species. Expand

The Roles of Plant Secondary Chemicals in Wet Tropical Ecosystems
TLDR
Studies are discussed of the following: floral fragrances as pollination attractants, legume seed toxins against insects, chemical variation on contrasting soil types relative to mammalian and insect herbivory, 4) chemical defense relative to successional status, 5) allelopathy, and 6) environmental constraints on production and variation of terpenoid resins in legumes.

Brementown revisited: interaction among allelochemicals in plants
TLDR
Interactions among co-occurring secondary compounds as regards herbivory, insect and otherwise, have been largely ignored by investigators who have instead concentrated on single classes of secondary products. Expand
Novel Aspects of Insect Plant Interactions
TLDR
A conceptual framework for evaluating the role of plant allelochemicals in the development of Insecticide Resistance and the role they play in the design of survival strategies of herBIVORs is presented. Expand
Volatile herbivore-induced terpenoids in plant-mite interactions: Variation caused by biotic and abiotic factors
TLDR
The role of terpenoids in the induced indirect defense of plants against herbivorous mites is reviewed and it is shown thatPredatory mites cope with this variation of HIS by innate recognition as well as temporary specialization to a certain HIS via learning. Expand
Botanical Defenses. (Book Reviews: Plant Resistance to Herbivores and Pathogens. Ecology, Evolution, and Genetics.)
TLDR
This volume draws together research from ecology, evolution, agronomy, and plant pathology to produce an ecological genetics perspective on plant resistance in both natural and agricultural systems. Expand
Biological activities of sesquiterpene lactones
TLDR
This review summarizes the present knowledge regarding the biological activities of sesquiterpene lactones and their structure-activity relationships and suggests their evolutionary significance in plants as deterrents against herbivores and anti-fungal, anti-bacterial allelopathic agents. Expand
The Role of Chemical Inhibition (Allelopathy) in Vegetational Composition
TLDR
The deterioration of old Salvia stands, apparently by auto-initoxication, suggests that allelopathy could be a significant factor in plant succession in many kinds of vegetation. Expand
Plant chemistry and insect species richness of British umbellifers
TLDR
There is no evidence from these data that biochemically diverse or unusual British umbellifers support less-species-rich assemblages of insect herbivores, and the data suggest that chemically diverse plants have more insect species. Expand
Metabolic costs of terpenoid accumulation in higher plants
TLDR
The metabolic costs of terpenoids accumulation in plants in the light of recent advances in terpenoid biochemistry are explored in relation to the assumptions and predictions of several current theories of plant defense, including the carbonnutrient balance hypothesis, the growth-differentiation balance hypotheses, and the resource availability hypothesis.

Plant strategies of manipulating predatorprey interactions through allelochemicals: Prospects for application in pest control
TLDR
Crop protection in the future should include tactics whereby man becomes an ally to plants in their strategies to manipulate predator-prey interactions through allelochemicals, which makes sense from an evolutionary point of view. Expand
