TLDR
It is demonstrated that the cuticle imposes substantial resistance to VOC mass transfer, acting as a sink/concentrator for VOCs and hence protecting cells from the potentially toxic internal accumulation of these hydrophobic compounds.Abstract:
The plant cuticle is the final barrier for volatile organic compounds (VOCs) to cross for release to the atmosphere, yet its role in the emission process is poorly understood. Here, using a combination of reverse-genetic and chemical approaches, we demonstrate that the cuticle imposes substantial resistance to VOC mass transfer, acting as a sink/concentrator for VOCs and hence protecting cells from the potentially toxic internal accumulation of these hydrophobic compounds. Reduction in cuticle thickness has differential effects on individual VOCs depending on their volatility, and leads to their internal cellular redistribution, a shift in mass transfer resistance sources and altered VOC synthesis. These results reveal that the cuticle is not simply a passive diffusion barrier for VOCs to cross, but plays the aforementioned complex roles in the emission process as an integral member of the overall VOC network.read more

Volatile terpenes – mediators of plant-to-plant communication
TL;DR: A review of the current knowledge of terpenes as volatile semiochemicals and their use as plant-to-plant signaling cues can be found in this paper, where the authors discuss how volatile terps may be perceived by plants, what are possible downstream signaling events in receiver plants, and how responses to different terpene cues might interact to orchestrate the net plant response to multiple stresses.

A peroxisomal heterodimeric enzyme is involved in benzaldehyde synthesis in plants
TL;DR: Using a combination of in vivo stable isotope labeling, classical biochemical, proteomics and genetic approaches, the authors showed that in petunia benzaldehyde is synthesized via the β-oxidative pathway in peroxisomes by a heterodimeric enzyme consisting of α and β subunits, which belong to the NAD(P)-binding Rossmann-fold superfamily.

TL;DR: The Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGAN2.1) as discussed by the authors is an update from the previous versions including MEGAN1.0, which was described for isoprene emissions by Guenther et al. (2006) and MEGan2.02, which were described for monoterpene and sesquiterpene emissions by Sakulyanontvittaya et al (2008).
