Origin of breath isoprene in humans is revealed via multi-omic investigations

Communications Biology, 2023
Plants, animals and humans metabolically produce volatile isoprene (C_5H_8). Humans continuously exhale isoprene and exhaled concentrations differ under various physio-metabolic and pathophysiological conditions.

A review on isoprene in human breath

Journal of Breath Research, 2023
We summarize the history and review the literature on isoprene in exhaled breath and discuss the current evidence and models that describe its endogenous origin and consequence for understanding isoprene levels and their variations in exhaled breath.

Strong isoprene emission response to temperature in tundra vegetation

Proceedings of the National Academy of Sciences of the United States of America, 2022
Significance How ecosystem–atmosphere exchange of reactive hydrocarbons, biogenic volatile organic compounds (BVOCs), responds to climate change may provide important feedbacks on the regional climate.

Nocturnal survival of isoprene linked to formation of upper tropospheric organic aerosol

Science, 2022
Isoprene is emitted mainly by terrestrial vegetation and is the dominant volatile organic compound (VOC) in Earth’s atmosphere. It plays key roles in determining the oxidizing capacity of the troposphere and the formation of organic aerosol.

Poplar phyllosphere harbors disparate isoprene-degrading bacteria

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Isoprene is a climate-active gas, produced in huge amounts by trees, yet we know little about its biogeochemical cycle. Bacteria able to grow on isoprene have been isolated from soils and sediments, but the phyllosphere, the principal ...

Isoprene and β-caryophyllene confer plant resistance via different plant internal signaling pathways.

Plant, Cell and Environment, 2021
Isoprene and other terpenoids are important biogenic volatile organic compounds in terms of atmospheric chemistry. Isoprene can aid plant performance under abiotic stresses, but the fundamental biological reasons for the high emissions are not completely

Isolation of isoprene degrading bacteria from soils, development of isoA gene probes and identification of the active isoprene-degrading soil community using DNA-stable isotope probing.

Environmental Microbiology, 2016
Emissions of biogenic volatile organic compounds (bVOCs), are an important element in the global carbon cycle, accounting for a significant proportion of fixed carbon.

Isoprene: An Antioxidant Itself or a Molecule with Multiple Regulatory Functions in Plants?

Antioxidants, 2021
Isoprene (C5H8) is a small lipophilic, volatile organic compound (VOC), synthesized in chloroplasts of plants through the photosynthesis-dependent 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway.

Regulation of plasmid-encoded isoprene metabolism in Rhodococcus, a representative of an important link in the global isoprene cycle

Environmental Microbiology, 2015
Emissions of biogenic volatile organic compounds (VOCs) form an important part of the global carbon cycle, comprising a significant proportion of net ecosystem productivity.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.
