<p>The invention relates to a method of testing agrochemicals for their capability to induce SAR in plants, said method comprising: (a) contacting a plant or plant part comprising a gene fragment coding for a lipoxygenage (LOX) the expression of which being inducible by salicylate, but not by naturally occurring plant pathogens, with an agrochemical; and (b) assaying the expression of said gene fragment, wherein the expression of said gene fragment indicates that the agrochemical has the capability to induce SAR. This method allows i.a. to screen for SAR inducing compounds in different plant species. Furthermore, kits for use in said methods are provided as well as a process for providing compounds having the capability of inducing SAR in plants, comprising the steps of: (a) generating a synthetic combinatorial library of different chemical compounds, and (b) screening the compounds of said library with the screening method according to this invention.</p> |
