Abstract: The chemically-inducible 27 kD subunit of the enzyme glutathione-S-transferase, isoform II (GST-II-27) and sequences encoding it are provided. In particular, a genomic DNA sequence encoding the gene promoter for the GST-II-27 subunit is provided. Then linked to an exogenous gene and introduced into a plant by transformation, and GST-II-27 promoter provides a means for the external regulation of expression of that exogenous gene. Transformation with DNA encoding glutathione-S-transferase polypeptides produces herbicide resistance transgenic plants.

Abstract: This invention pertains to methods for using oxalate oxidase in plant pathology. A substantially pure gene encoding the oxalate oxidase enzyme is elucidated. The expression product of the gene which can be stably incorporated into a foreign plant host has a unique profile including a pH optimum of 3.5, a positive heat stability, a single sub-unit of approximately 25 kilodaltons and protease stability. The methodology of this invention exploiting oxalate oxidase for protection against oxalic acid encompasses providing to a plant in need of oxalic acid protection an oxalic acid degrading enzyme in an amount sufficient to protect the plant from the oxalic acid.

Abstract: Antimicrobial proteins capable of isolation from seeds of Aralia or Impatiens show a wide range of antifungal activity and some antibacterial activity. DNA encoding the proteins may be isolated and incorporated into vectors. Plants transformed with this DNA may be produced. The proteins find commerical application as antifungal or antibacterial agents; transformed plants will show increased disease-resistance. The invention further provides a method of expressing polyproteins in transgenic plants using DNA constructs based on the structure of the gene encoding the Impatiens antimicrobial proteins.
