Phytoremediation of Cu and Zn by vetiver grass in mine soils amended with humic acids

Vargas C, Pérez-Esteban J, Escolástico C, Masaguer A, Moliner Environmental science and pollution research international, 2016 ABSTRACT: Phytoremediation of contaminated mine soils requires the use of fast-growing, deep-rooted, high-biomass, and metal-tolerant plants with the application of soil amendments that promote metal uptake by plants. A pot experiment was performed to evaluate the combined use of… Read more »

Vetiver grass: An environment clean-up tool for heavy metal contaminated iron ore mine-soil

Banerjee R, Goswami P, Khanindra P, Mukherjee A Ecological Engineering, 2016 ABSTRACT: Aims Vetiver grass – Chyrsopogon zizanioides (L.) Roberty is a known plant tolerant to heavy metals and its use as an alternative method for rehabilitation of iron ore mine-soil has been investigated. Methods A pot experiment was performed over a period of three… Read more »

Herbal bioactivation: the good, the bad and the ugly

Zhou S, Koh HL, Gao Y, Gong ZY, Lee EJ Life sciences, 2004 ABSTRACT: It has been well established that the formation of reactive metabolites of drugs is associated with drug toxicity. Similarly, there are accumulating data suggesting the role of the formation of reactive metabolites/intermediates through bioactivation in herbal toxicity and carcinogenicity. It has… Read more »

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 »

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 »
