Potential Implications of the Sesquiterpene Presence over the Remote Marine Boundary Layer in the Arctic Region

Atmosphere, 2023
We present reactive VOC observations over the North Pacific and the Arctic Ocean from airborne and shipborne measurements, investigating, in particular, distributions of biogenic volatile organic compounds that may be emitted from phytoplankton.

Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

Advanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Biosynthese des vollständig gesättigten C16‐Homosesquiterpens Descartan durch Deprotonierung mit Cyclopropanierung

Angewandte Chemie, EarlyView.
Eine nicht‐kanonische C16‐Sesquiterpensynthase aus Morganella morganii produziert das ungewöhnliche Grundgerüst Descartan. Ihr Cyclisierungsmechanismus wurde mittels Isotopenmarkierungsexperimenten und DFT‐Berechnungen aufgeklärt. Gezielte Mutagenese veränderte die Enzymfunktion und führte zu alternativen Produkten, darunter Voltairen, dessen ...

Sesquiterpenes and oxygenated sesquiterpenes dominate the emissions of downy birches [PDF]

, 2020
Abstract. Even though isoprene and monoterpene (MT) emissions of boreal needle trees have been studied quite intensively, there is less knowledge on the emissions of broadleaved deciduous trees and emissions of larger terpenes and oxygenated volatile organic compounds (OVOCs).

Biosynthesis of the Fully Saturated C16 Homosesquiterpene Descartane Through Deprotonation With Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
A non‐canonical C16 sesquiterpene synthase from Morganella morganii produces the unusual scaffold descartane. Its cyclisation mechanism was rationalised by isotopic labelling experiments and DFT calculations. Site‐directed mutagenesis altered enzyme function, resulting in alternative products, including voltairene, which requires a different ...

Genetic Architecture of Capitate Glandular Trichome Density in Florets of Domesticated Sunflower (Helianthus annuus L.)

Frontiers in Plant Science, 2018
Capitate glandular trichomes (CGT), one type of glandular trichomes, are most common in Asteraceae species. CGT can produce various secondary metabolites such as sesquiterpene lactones (STLs) and provide durable resistance to insect pests.

Spectroscopic and In Silico Determination of the Structural and Antioxidant Properties of Essential Oils From Lavandula Species Cultivated in the Silivri Region of Istanbul

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plants are important sources of bioactive compounds that contribute to nutrition, health maintenance, and disease prevention. In this study, the chemical composition and antioxidant potential of essential oils obtained from Lavandula angustifolia “Sevtopolis” and Lavandula × intermedia cultivated in the Silivri region of Istanbul were ...
