DNA, DNA CONSTRUCTS, CELLS AND PLANTS DERIVED THEREFROM

摘要

DNA constructs comprise a DNA sequence homologous to some or all of the gene encoded by the clone pTOM75. The constructs may further comprise a transcriptional initiation region operative in plants for transcribing this DNA sequence, optionally in the antisense direction to produce mRNA complementary to the pTOM75 gene. From such constructs may be derived transformed plant cells and plants in which expression of the pTOM75 gene is inhibited: fruit from the plants (such as tomatoes) can show modified ripening properties, such as increased acid content.
