title: Identification of mucondialdehyde as a novel stress metabolite.
abstract: In a survey of antifungal stress compounds induced by cupric chloride we found that leaves of Chenopodium album exuded a highly fungitoxic metabolite mucondialdehyde (trans-2,trans-4-hexadienedial), which was associated with 13-oxo-9,11-tridecadienoic acids (cis-9,trans-11 and trans-9,trans-11 isomers) presumably resulting from beta-scission of 13-hydroperoxy-octadecadi(tri)enoic acid. The biogenesis and role as a general defensive agent in plants are briefly discussed.
