The impact of the plant activator, cis-jasmone, upon the secondary metabolism of wheat seedlings, Triticum aestivum cv. Solstice, was investigated. Increased levels of benzoxazinoids, such as DIMBOA, and phenolic acids were observed in treated plants. These results show, for the first time, that cis...
