DNA, DNA CONSTRUCTS, CELLS AND PLANTS DERIVED THEREFROM

摘要

DNA constructs comprise a DNA sequence homologous to some or all of the pectinesterase gene encoded by the clone pB8 (Sequence ID No. 1), under control of a transcriptional initiation region operative in plants for transcribing this DNA sequence, optionally in the antisense direction to produce RNA complementary to the gene mRNA. From such constructs may be derived transformed plant cells and plants in which expression of pectinesterase genes is inhibited: fruit from the plants (such as tomatoes) can show modified ripening properties.
