COMPOSITIONS AND METHODS FOR REGULATING PLANT GENE EXPRESSION

摘要

The invention provides an isolated promoter polynucleotide comprising at least two sequence motifs with at least 70 % identity to the sequence SEQ ID No: 1, wherein the promoter polynucleotide is capable of controlling transcription of an operably linked polynucleotide in a plant and is capable of being modulated by a MYB transcription factor, specifically MdMYB 10. The invention also provides genetic constructs and vectors comprising the promoter polynucleotide sequence, and transgenic plant cells and transgenic plants comprising the promoter polynucleotide sequence, genetic constructs or vectors of the invention. The invention also provides methods for producing plants with modified gene expression and modified phenotype. The invention further provides plants produced by the methods of the invention.
