Defense and signalling metabolites of the crucifer Erucastrum canariense: Synchronized abiotic induction of phytoalexins and galacto-oxylipins

Publication date: July 2017 Source:Phytochemistry, Volume 139 Author(s): M. Soledade C. Pedras, Q. Huy To Erucastrum canariense Webb & Berthel. (Brassicaceae) is a wild crucifer that grows in rocky soils, in salt and water stressed habitats, namely in the Canary Islands and similar environments. Abiotic stress induced by copper chloride triggered formation of a phytoalexin and galacto-oxylipins in E. canariense, whereas wounding induced galacto-oxylipins but not phytoalexins. Analysis of the metabolite profiles of leaves of E. canariense followed by isolation and structure determination afforded the phytoalexin erucalexin, the phytoanticipin indolyl-3-acetonitrile, the galacto-oxylipins arabidopsides A, C, and D, and the oxylipin 12-oxophytodienoic acid. In addition, arabidopsides A and D were also identified in extracts of leaves of Nasturtium officinale R. Br. Graphical abstract
