Plant Volatile Organic Compounds
Plants emit volatile organic compounds VOCs which they use to attract pollinators protect against certain environmental stressors and repel herbivores. Proceedings of the National Academy of Sci-ences 53.

Plants synthesize an amazing diversity of volatile organic compounds VOCs that facilitate interactions with their environment from attracting pollinators and seed dispersers to protecting themselves from pathogens parasites and herbivores.
Plant volatile organic compounds. Huang M Sanchez-Moreiras AM Abel C Sohrabi R Lee S Gershenzon J Tholl D 2012 The major volatile organic compound emitted from Arabidopsis thaliana flowers the sesquiterpene E-β-caryophyllene is a defense against a bacterial pathogen. Volatile organic compounds VOCs emitted by microorganisms have demonstrated an important role to improve growth and tolerance against abiotic stress on plants. Plants may eavesdrop on volatile organic compounds VOCs released by herbivore-attacked neighbors to activate defenses before being attacked themselves.
A relatively large group of plant natural products consists of volatile organic compounds VOCs lipophilic liquids with low molecular weight and high vapor pressure at ambient temperatures. Plant volatile organic compounds VOCs have important roles in plant adaptation to the environment and serve as infochemicals in multitrophic interactions. These signals take the form of airborne chemicals called volatile organic compounds VOCs released from one plant and detected by another and plant biologists have found that a.
Recent progress in -omics technologies resulted in the isolation of genes encoding enzymes responsible for. Volatile organic material of plant origin in the atmosphere. These interactions often change rapidly over time so a quick response to those changes is required.
Plants produce a broad range of VOCs with the largest groups being terpenoids compounds with an isoprenoid structure similar to that of the terpene hydrocarbons and green leaf volatiles GLVs. GLVs are best known as the smell that is produced by freshly mown grass. These airborne compounds are constitutively released or synthesized in reaction to biotic and abiotic stimuli and perform different ecological functions such as protecting plants from extreme.
This group of volatiles mainly consists of C 6 -aldehydes C 6 -alcohols and their acetates. CREAF researchers study the close relationship between these compounds and the microorganisms populating the planet. Rasmussen R Went F.
Pages 217-260 in Sharkey T Holland E Mooney H eds. Volatile organic compounds VOCs are emitted by plants as a consequence of their interaction with biotic and abiotic factors and have a very important role in plant evolution. The significance of higher plants in the emission of sulfur compounds from terrestrial ecosystems.
Most studies have used Arabidopsis thaliana as a model plant extending to other plants of commercial interest in the last years. Volatile organic compounds VOCs are emitted by plants as a consequence of their interaction with biotic and abiotic factors and have a very important role in plant evolution. It is now well documented that VOCs emitted by the roots in the plant rhizosphere also play important ecological roles in the soil ecosystem notably in plant defence because they are involved in interactions between plants phytophagous pests and organisms of the third trophic level.
Floral VOCs are often involved in defense and pollinator attraction. Trace gas emissions by. Transcriptome and signal cascade analyses.
Global climate change factors such as increased atmospheric carbon dioxide ozone and temperature could alter how insects perceive such compounds. Physical properties of these compounds allow them to freely cross cellular membranes and be released into the surrounding environment Pichersky et al 2006. This upregulation is independent of the types of sulfur sources in the plant and can.
Interestingly the microbial VOCs are characterized by its biodegradable structure quick action. Based on precise quantification of plant volatiles we discovered that the plant volatile organic compound E2hexenal at concentrations that were similar to or lower than those in tissues of strawberry and tomato fruits upregulates sulfate assimilation in spores and hyphae of the phytopathogenic fungus Botrytis cinerea. Aboveground plants release volatile organic compounds VOCs that act as chemical signals between neighbouring plants.
Plants emit complex mixtures of low molecular weight volatile molecules containing nitrogen and aromatic compounds named volatile organic compounds VOCs.
