摘要

Investigation of phytoalexin production using abiotic elicitation showed that the phytoalexin rapalexin A was produced by both Thellungiella halophila and Arabidopsis thaliana, but while A. thaliana produced camalexin, T. halophila produced wasalexins A and B and methoxybrassenin B. Considering that the genome of T. halophila is being sequenced currently and that the wasalexin pathway present in T. halophila is expected to involve a number of genes also present in Brassica species, our discovery should facilitate the isolation of genes involved in biosynthetic pathways of phytoalexins of the most economically important crucifer species.
