Abstract
The present invention relates generally to transcriptional control sequences. Generally, the present invention relates to transcriptional control sequences that specifically or preferentially direct expression of a nucleotide sequence of interest in a plant egg cell. The present invention is predicated, in part, on the identification of transcriptional control sequences derived from EC1 genes which, in preferred embodiments, direct preferential expression in an egg cell of at least one plant taxon.
Claims11
1-57. (canceled)
A nucleic acid construct comprising:
- a plant female gamete-specific transcriptional control sequence, wherein said transcriptional control sequence comprises (i) the nucleotide sequence set forth in SEQ ID NO:
- 25, or (ii) a functionally active fragment or variant of (i), said functionally active fragment or variant comprising a nucleotide sequence which is at least 95% identical to SEQ ID NO:
- 25 over the full length of SEQ ID NO:
- 25, and wherein said transcriptional control sequence is operably connected to a nucleotide sequence of interest which is heterologous with respect to the transcriptional control sequence and induces expression of the nucleotide sequence of interest in egg cells.
