Vascular-preferred promoters
View Patent ↗The present invention relates to the regulation of polynucleotide transcription and/or expression. In particular, this invention relates to polynucleotide regulatory sequences isolated from Eucalyptus grandis and Pinus radiata that are capable of conferring vascular-preferred polynucleotide transcription in plant cells. Constructs and methods for using the inventive regulatory sequences for modifying transcription of endogenous and/or heterologous polynucleotides also are included in the invention.
1. An isolated nucleic acid molecule comprising the sequence of SEQ ID NO: 47.
2. The isolated nucleic acid molecule of claim 1 , wherein said sequence is operably linked to a gene encoding an RNA interference molecule.
3. A vector comprising the isolated nucleic acid molecule of claim 1 , wherein said sequence is operably linked to a gene encoding an RNA interference molecule.
4. A plant cell transformed with the vector of claim 3 .
5. A transgenic plant comprising the plant cell of claim 4 , wherein said transgenic plant expresses said gene encoding said RNA interference molecule.
6. The transgenic plant of claim 5 , wherein said plant is selected from angiosperms and gymnosperms.
