Biogenic Volatile Organic Compounds (VOC): An Overview on Emission, Physiology and Ecology
TLDR
In this article, an overview of the actual knowledge of the biogenic emissions of some volatile organic compounds (VOCs), i.e., isoprene, terpenes, alkanes, alkenes, carbonyls, alcohols, esters, and acids, is presented.Abstract:
This overview compiles the actual knowledge of the biogenic emissions of some volatile organic compounds (VOCs), i.e., isoprene, terpenes, alkanes, alkenes, alcohols, esters, carbonyls, and acids. We discuss VOC biosynthesis, emission inventories, relations between emission and plant physiology as well as temperature and radiation, and ecophysiological functions. For isoprene and monoterpenes, an extended summary of standard emission factors, with data related to the plant genus and species, is included. The data compilation shows that we have quite a substantial knowledge of the emission of isoprene and monoterpenes, including emission rates, emission regulation, and biosynthesis. The situation is worse in the case of numerous other compounds (other VOCs or OVOCs) being emitted by the biosphere. This is reflected in the insufficient knowledge of emission rates and biological functions. Except for the terpenoids, only a limited number of studies of OVOCs are available; data are summarized for alkanes, alkenes, carbonyls, alcohols, acids, and esters. In addition to closing these gaps of knowledge, one of the major objectives for future VOC research is improving our knowledge of the fate of organic carbon in the atmosphere, ending up in oxidation products and/or as aerosol particles.read more

Isoprene Produced by Leaves Protects the Photosynthetic Apparatus against Ozone Damage, Quenches Ozone Products, and Reduces Lipid Peroxidation of Cellular Membranes
TL;DR: The results indicate that isoprene may exert its protective action at the membrane level, although a similar effect could be obtained if isopane reacted with ozone before forming active oxygen species, and suggest that endogenous isopene has an important antioxidant role in plants.

Heterogeneous Atmospheric Aerosol Production by Acid-Catalyzed Particle-Phase Reactions
TL;DR: If acid-catalyzed heterogeneous reactions of SOA products are included in current models, the predicted SOA formation will be much greater and could have a much larger impact on climate forcing effects than the authors now predict.

Abiotic stresses and induced BVOCs.
TL;DR: In conclusion, oxidative and thermal stresses are relieved in the presence of volatile terpenes and C6 compounds, and methyl salicylate are thought to promote direct and indirect defence by modulating the signalling that biochemically activate defence pathways.

TL;DR: It is proposed that natural VOC oxidation, notably of isoprene, recycles OH efficiently in low-NOx air through reactions of organic peroxy radicals, which demonstrates that the biosphere maintains a remarkable balance with the atmospheric environment.

TL;DR: In this article, the authors proposed a framework to integrate biogeochemical processes into designing, implementing, and evaluating the net effectiveness of green infrastructure, and provide examples for GHG mitigation, stormwater runoff mitigation, and improvements in air quality and health.

TL;DR: In this article, the authors developed a global model to estimate emissions of volatile organic compounds from natural sources (NVOC), which has a highly resolved spatial grid and generates hourly average emission estimates.

Exploitation of herbivore-induced plant odors by host-seeking parasitic wasps.
TL;DR: Corn seedlings release large amounts of terpenoid volatiles after they have been fed upon by caterpillars, and females of the parasitic wasp Cotesia marginiventris (Cresson) learn to take advantage of those plant-producedvolatiles to locate hosts when exposed to these volatile in association with hosts or host by-products.
