Abstract
Recombinant DNA comprises promoter and terminator base sequences respectively upstream and downstream of an inverted base sequence complementary to a substantial sequence of bases in polygalacturonase mRNA. The antisense mRNA produced thereby delays softening of fruit, in particular tomatoes.
Claims9
Recombinant DNA comprising:
- an upstream promoter base sequence,
- a base sequence for transcription into mRNA under control of said upstream promoter base sequence comprising coding and template strands, and
- a downstream transcription terminator base sequence,
- wherein the coding strand of said base sequence for transcription comprises an inverted sequence of bases complementary to a run of bases of pectin esterase mRNA, wherein the transcript of said base sequence for transcription substantially inhibits expression of tomato pectin esterase.
