Growth of Cultured Carrot Cells as Affected by Glyphosate, Asulam and Various Plant Metabolites
… (4-aminobenzensulphonyl carbamate)} and various plant metabolites and were harvested for fresh weight determinations by filtering on miracloth under vacuum. Glyphosate was autoclaved with the medium, but asulam and other additions to the culture medium were filter sterilized.

Catalytic site mutagenesis of cytochrome P450 6B1v1
… in species ranging from bacteria to insects, plants, and mammals. In insects, P-450s have several functional roles, including growth, development, feeding, resistance to pesticides, and tolerance to plant toxins. Cytochrome P-450 6B1v1 (CYP6B1v1) is a membrane-bound P-450 derived from larvae …

Signal-metabolome interactions in plants
… feasibility of a simultaneous analysis of plant metabolites and phytohormones in one sample set-up was tested by studies on the analytical robustness of the metabolite profiling protocol. The recovery of plant metabolites proved to be satisfactory robust against variations in the extraction …

Crystal Engineering of Flavonoids
… Flavonoids are polyphenolic secondary plant metabolites that are present in varying levels in fruits, vegetables and beverages. The "French paradox", low cardiovascular mortality rate in spite of high intake of saturated fat among the Mediterranean populations made flavonoids an …

Microbial glucosinolate metabolism: Characterization of Enterococcus faecalis XL1 and functional analysis of a GH4 enzyme
Glucosinolates (GSLs), sulfur-containing plant metabolites abundant in cruciferous vegetables, are hydrolyzed to isothiocyanates (ITCs) – bioactive compounds with antimicrobial, anticancer, and anti-inflammatory properties. When plant myrosinases are inactivated by cooking, gut microbes become the …

Metabolomic approaches to understanding the auxin and ethylene response in Arabidopsis roots
… many important physiological processes in plants, including the initiation of lateral root formation and the response to gravity. These occur in part through alterations in the levels of flavonoids, specialized plant metabolites that have been shown to act as negative regulators of auxin …

Pseudomonas/Brachypodium as a Model System for Studying Rhizosphere Plant Microbe Interactions Under Water Stress
… well-studied mechanisms of drought tolerance in plants, the interactions between plants and their microbiome during water stress are still poorly understood. This missing knowledge is crucial for the exploitation of beneficial microbial communities to improve the sustainability of agriculture …

The ecology of venom use in the Javan Slow Loris (Nycticebus Javanicus) and its implications for conservation
… Java. Venom may be sequestered from secondary plant metabolites and noxious arthropods, as the latter were abundant at the study site. Javan slow lorises fed extensively on gum (56 %) and 95 % of faecal samples contained arthropod remains. With regard to the ecological function, ranging …

Physiological studies with the experimental herbicide isouron
… These studies included two plant metabolites of isouron, a monomethylurea (N-(5-(1,1-dimethylethyl)-3-isoxazolyl)-N-methylurea) and a urea derivative (N-(5-(1,1-dimethylethyl)-3-isoxazolyl)-urea). The compounds were examined for their effects on four metabolic processes of …

Advanced applications of Raman spectroscopy and super-resolution imaging of biological and plant materials
<p>Plants are an essential resource for the Earth, yet there is still a significant lack of knowledge about the cells, tissues, and organs of plants compared to the human body. There is a great need for sensitive methods to analyze plants and biological materials to gain an in situ understanding of …

UV-assisted isomerization studies of active compounds in bush tea (Athrixia phylicoides) leaf extracts and investigations of their potential to inhibit acid corrosion of mild steel and zinc
… can be controlled by using corrosion inhibitors. Plant metabolites undergo geometrical isomerization under the influence of UV light radiation. The use of corrosion inhibitors is one of the useful methods to reduce or decrease corrosion on metals. While synthetic inhibitors are useful in …
