Abstract
Novel DNA constructs are provided which may be used as molecular probes or inserted into a plant host to provide for modification of transcription of a DNA sequence of interest in ovary tissue, particularly in very early fruit development. The DNA constructs comprise a transcriptional initiation regulatory region associated with gene expression in ovary tissue from immediately prior to anthesis through flower senescence.

A DNA transcription construct comprising a tomato pZ130 transcriptional initiation region joined in the direction of transcription to a heterologous DNA sequence of interest under the regulatory control of said initiation region.
A plant comprising:
- plant cells comprising a DNA transcription construct in the genome of said cells, said construct comprising
- a tomato pZ130 transcriptional initiation region joined in the direction of transcription to a DNA sequence of interest under the regulatory control of said initiation region, and a transcriptional termination region,
- wherein said DNA sequence of interest is heterologous to at least one of said transcriptional initiation and termination regions.
A method for producing a polypeptide of interest in tomato ovary tissue, said method comprising:
- growing a tomato plant to produce fruit, wherein cells of said fruit comprise in their genome a transcription construct comprising a tomato pZ130 transcriptional initiation region joined in the direction of transcription to a DNA sequence of interest under the regulatory control of siad initiation region, said construct further comprising a transcriptional termination region,
- wherein said DNA sequence of interest is heterologous to at least one of said transcriptional initiation and termination regions, and wherein said DNA sequence of interest encodes said polypeptide of interest.
