Camalexin accumulation in Arabis lyrata

M Zook et al. Phytochemistry. 1998 Dec.

Abstract

Inoculation of leaves of Arabis lyrata with either a bacterial pathogen Pseudomonas syringae pv. maculicola strain ES4326 or Cochliobolus carbonum, a fungal nonpathogen of A. lyrata, resulted in the accumulation of a compound with similar chromatographic and fluorescent properties to that of camalexin (I), a phytoalexin produced by Arabidopsis thaliana. A. lyrata is closely related to A. thaliana. High resolution electron impact mass spectroscopic and proton NMR analysis confirmed that the compound produced by A. lyrata is camalexin.
