Isoprene Peroxy Radical Dynamics
Journal of the American Chemical Society, 2017 Approximately 500 Tg of 2-methyl-1,3-butadiene (isoprene) is emitted by deciduous trees each year. Isoprene oxidation in the atmosphere is initiated primarily by addition of hydroxyl radicals (OH) to C4 or C1 in a ratio 0.57 ± 0.03 (1σ) to produce two sets of distinct allylic radicals.

Anaerobic Biohydrogenation of Isoprene by Acetobacterium wieringae Strain Y
mBio, 2022 Isoprene is a ubiquitously distributed, biogenic, and climate-active organic compound. Microbial isoprene degradation in oxic environments is fairly well understood; however, studies exploring anaerobic isoprene metabolism remain scarce, with no isolates

Evidence for a Putative Isoprene Reductase in Acetobacterium wieringae
mSystems, 2023 Recent discoveries of isoprene-metabolizing microorganisms suggest they might play an important role in the global isoprene budget. Under anoxic conditions, isoprene can be used as an electron acceptor and is reduced to methylbutene. This study describes

Isoprene Increases Thermotolerance of Isoprene-Emitting Species [PDF]
Plant Physiology, 1997 Abstract Isoprene-emitting plants lose a large portion of their assimilated C as isoprene. Because isoprene synthesis can be regulated, it has been assumed that isoprene benefits the plant. Since the rate of isoprene emission from leaves is highly responsive to temperature, we hypothesized that isoprene benefits plants by increasing ...

Non-enzymatic formation of isoprene and 2-methyl-3-buten-2-ol (2-MBO) by manganese
Scientific Reports, 2022 It has been suggested that isoprene synthesis by isoprene synthase (IspS) proceeds via a substrate-assisted mechanism. The authors observed a non-enzymatic isoprene formation by Mn2+, which represents the basis of IspS enzyme reaction.

Origin of breath isoprene in humans is revealed via multi-omic investigations
Communications Biology, 2023 Plants, animals and humans metabolically produce volatile isoprene (C5H8). Humans continuously exhale isoprene and exhaled concentrations differ under various physio-metabolic and pathophysiological conditions.

Isoprene in poplar emissions: effects on new particle formation and OH concentrations [PDF]
Atmospheric Chemistry and Physics, 2012 Stress-induced volatile organic compound (VOC) emissions from transgenic Grey poplar modified in isoprene emission potential were used for the investigation of photochemical secondary organic aerosol (SOA) formation. In poplar, acute ozone stress induces

Plant Direct, 2023 Isoprene has recently been proposed to be a signaling molecule that can enhance tolerance of both biotic and abiotic stress. Not all plants make isoprene, but all plants tested to date respond to isoprene.
