Plant defense against herbivores: chemical aspects

Mithöfer A, Boland W Annual review of plant biology, 2012 ABSTRACT: 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 are induced after attack. Many compounds act directly on the herbivore, whereas others act indirectly via the… Read more »

A review and synthesis of monoterpene speciation from forests in the United States

Gerona C, Rasmussenb R, Arntsc RR, Guentherd A Atmospheric Environment, 2000 ABSTRACT: The monoterpene composition (emission and tissue internal concentration) of major forest tree species in the United States is discussed. Of the 14 most commonly occurring compounds (α-pinene, β-pinene, Δ3-carene, d-limonene, camphene, myrcene, α-terpinene, β-phellandrene, sabinene, ρ-cymene, ocimene, α-thujene, terpinolene, and γ-terpinene), the first… Read more »

Factors affecting secondary metabolite production in plants: volatile components and essential oils

Figueiredo CA, Barroso JG, Pedro LG, Johannes J. C. Scheffer Flavour and Fragrance Journal, 2008 ABSTRACT: The presence, yield and composition of secondary metabolites in plants, viz. the volatile components and those occurring in essential oils, can be affected in a number of ways, from their formation in the plant to their final isolation. Several of the… Read more »

Regulation of monoterpene accumulation in leaves of peppermint

Gershenzon J, McConkey ME, Croteau RB Plant physiology, 2000 ABSTRACT: Plants synthesize numerous classes of natural products that accumulate during development and are thought to function as constitutive defenses against herbivores and pathogens. However, little information is available about how the levels of such defenses are regulated. We measured the accumulation of monoterpenes, a model… Read more »

The role of structure and molecular properties of terpenoids in determining their antimicrobial activity

Griffin SG, Wyllie SG, Julie L, Markham, Leach DN Flavour and Fragrance Journal, 1999 ABSTRACT: The minimum inhibitory concentrations (MIC) of 60 terpenoids against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Candida albicans have been determined. Hierarchical cluster analysis was used to group the compounds into five groups according to their activity patterns against the four microorganisms. K-Means… Read more »

Regulation of essential oil production in plants

Sangwan NS, Farooqi AHA, Shabih F, Sangwan RS Plant Growth Regulation, 2001 ABSTRACT: This review provides a summary of the physiological dynamics and regulation of essential oil production, from the literature and available information on diverse volatile oil crops. Essential oil production is highly integrated with the physiology of the whole plant and so depends… Read more »

Evolution of secondary metabolites from an ecological and molecular phylogenetic perspective

Wink M Phytochemistry, 2003 ABSTRACT: Secondary metabolites, at least the major ones present in a plant, apparently function as defence (against herbivores, microbes, viruses or competing plants) and signal compounds (to attract pollinating or seed dispersing animals). They are thus important for the plant’s survival and reproductive fitness. Secondary metabolites therefore represent adaptive characters that… Read more »

Seasonality of isoprenoid emissions from a primary rainforest in central Amazonia

Alves EG, Jardine K, Tota J, Jardine A ,Ana Maria Yãnez-Serrano, Karl T, Tavares J, Nelson B, Gu D, Stavrakou T, Martin S, Artaxo P, Manzi A, Guenther A Atmospheric Chemistry and Physics, 2016 ABSTRACT: Tropical rainforests are an important source of isoprenoid and other volatile organic compound (VOC) emissions to the atmosphere. The seasonal variation of these… Read more »

Plant essential oils for pest and disease management

Murray B Isman Crop Protection, 2000 ABSTRACT: Certain essential plant oils, widely used as fragrances and flavors in the perfume and food industries, have long been reputed to repel insects. Recent investigations in several countries confirm that some plant essential oils not only repel insects, but have contact and fumigant insecticidal actions against specific pests,… Read more »

Anticonvulsant activity of β-caryophyllene against pentylenetetrazol-induced seizures

de Oliveira CC, de Oliveira CV, Grigoletto J, Ribeiro LR, Funck VR, Grauncke AC, de Souza TL, Souto NS, Furian AF, Menezes IR, Oliveira MS Epilepsy & behavior : E&B, 2016 ABSTRACT: Increasing evidence suggests that plant-derived extracts and their isolated components are useful for treatment of seizures and, hence, constitute a valuable source of… Read more »
