Troposphere ozone (O3) is an important photochemical pollutant due to its high reactivity and phytotoxicity. Plants can show microscopic damage caused by this gas before the detection of visible symptoms. The present study aimed to improve our knowle

ABSTRACT In this study, we demonstrated that Tetranychus urticae Koch (Acari: Tetranychidae), a generalist herbivore, induces volatile organic compounds (VOC) in Croton floribundus Spreng., a pioneer species widely used in Brazilian urban area. We pe

A pentacyclic triterpene, 3β,30-dihydroxy-lup-20(29)-ene, was isolated from the powder extract of Maytenus imbricata. The structure and stereochemistry of the compound were established by spectroscopic techniques and unambiguously determined by sing

Plants emit a broad number of Biogenic Volatile Organic Compounds (BVOCs) that can impact urban ozone (O3) production. Conversely, the O3 is a phytotoxic pollutant that causes unknown alterations in BVOC emissions from native plants. In this sense, h

The present study aimed to study if the intensity and precocity of short-term leaf responses of Nicotiana tabacum 'Bel-W3' depended on the daily atmospheric levels of ozone and/or daily meteorological conditions in a State Park located in the city of

Here, we proposed that volatile organic compounds (VOC), specifically methyl salicylate (MeSA), mediate the formation of calcium oxalate crystals (COC) in the defence against ozone (O3) oxidative damage. We performed experiments using Croton floribun
