  • Patent number: 5569831
    Abstract: Methods of creating transgenic tomatoes containing a lowered level of polygalacturonase isoform 1 are disclosed. The isolation of a DNA sequence encoding the polygalacturonase beta-subunit is disclosed. The beta-subunit sequence can be used to construct both sense and antisense plant expression constructions which can be transformed into tomato plants. The transgenic tomato plants have altered levels of polygalacturonase isoforms in that the level of isoform 1 is dramatically reduced. The resulting tomato fruit has a polygalacturonase activity level that is more heat labile, and thus more convenient for processing, and an increased level of soluble pectins.
