This invention relates to 9-Hydroperoxide Lyase or 9-HPO lyase enzymes. DNA constructs useful for the expression of a plant HPO lyase in a cell are described. Furthermore, DNA constructs useful for the antisense expression of a 9-HPO lyase in a plant cell are described. Such constructs will contain a DNA sequence encoding the 9-HPO lyase of interest under the control of regulatory elements capable of preferentially directing the expression of the 9-HPO lyase in plant tissue, when such a construct is expressed in a trangenic plant. This invention also relates to methods of using a DNA sequence encoding a 9-HPO lyase for the modification of the volatile aldehydes in plant tissues, as well as for methods of increasing disease resistance in a plant. 9-HPO Lyase sequences exemplified herein are obtained from Arabidopsis.
