Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

open access: yesJournal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Synergistic O_3 + OH oxidation pathway to extremely low-volatility dimers revealed in β-pinene secondary organic aerosol [PDF]

open access: yes, 2018
Dimeric compounds contribute significantly to the formation and growth of atmospheric secondary organic aerosol (SOA) derived from monoterpene oxidation. However, the mechanisms of dimer production, in particular the relevance of gas- vs.

An investigation of the rate of biogenic volatile organic carbon emissions from commercial crop and plantation species in the Mpumalanga Province [PDF]

open access: yes, 2010
Volatile Organic Carbons (VOCs) are extremely reactive compounds and play an important role in the ozone chemistry of the atmosphere. Biogenic Volatile Organic Compounds (BVOCs) are estimated to contribute ~1015 g C y-1 per year to the atmosphere which ...

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Adsorption and Dilational Viscoelasticity of Saponin at the β-Pinene/Water and Air/Water Interfaces

open access: yesColloids and Interfaces
Understanding adsorption and interfacial properties of surface-active agents at interfaces is crucial to the formation and stability of colloidal systems such as emulsions and foams. In this work, interfacial tension and viscoelasticity of saponin at the
