The essential oil obtained from the fresh leaves of Zanthoxylum alatum was analysed by gas chromatography/mass spectrometry (GC/MS). Fourteen components were identified, and linalool (30.58%), 2-decanone (20.85%), β -fenchol (9.43%), 2-tridecanone (8.86%), β -phellandrene (5.99%), Sabinene (4.82%), and α -pinene
In this study we assessed the dynamic changes of 2-tridecanone in a herbivorous mite (Tetranychus urticae) on tomato (Lycopersicon esculentum, cv. 'Moneymaker'), a plant with methyl ketones in the tetracellular tips of the glandular trichomes (Type VI). We showed that

A field study was conducted to investigate the impact of soil amendments on concentrations of two volatile organic compounds, 2-undecanone and 2-tridecanone, in onion bulbs. The soil in five plots was mixed with sewage sludge, five plots were mixed with
The trichomes of the wild tomato species Solanum habrochaites subsp. glabratum synthesize and store high levels of methylketones, primarily 2-tridecanone and 2-undecanone, that protect the plants against various herbivorous insects. Previously, we identified cDNAs encoding two proteins necessary for methylketone
Earlier studies of resistance to the tomato toxin 2-tridecanone revealed similar levels of resistance among tomato and cucumber strains of Tetranychus urticae, whereas we anticipated the tomato strains to have a higher resistance. Between-strain differences, however, may be concealed by
