This invention describes novel lipoxygenase genes and promoters, transit peptides and proteins derived therefrom. More specifically, this invention describes novel promoters that confer chemically inducible but not wound- or pathogen-inducible expression to an associated nucleotide sequence. The invention further describes peptides capable of targeting and associated protein to plastids and proteins having lipoxygenase activity which can be used to inhibit fungal mycotoxins. The invention also describes recombinant sequences containing such promoter sequences, and/or sequences encoding transit peptides and proteins according to the invention. The said recombinant DNA sequences may be used to create transgenic plants, but especially transgenic plants expressing a nucleotide sequence of interest in response to chemicals but not in response to wounding or pathogens.
