Chimeric Promoters and methods to regulate gene expression in Plants

摘要

It provides a method for producing a Chimeric polynucleotide Promoter capable of Controlling the transcription of a polynucleotide operably linked to a Plant Cell or Plant, wherein the method comprises: a) The combination of at least a sequence Motif that includes a sequence co At least 70% identity with Nu00f8 sec id: 1, (Malus Domestic)11 or 12 (Malus Domestic) Pyrus communis) and (b) other polynucleotide sequence. Also provides Chimeric Promoters comprising polynucleotide sequences defined in (a) and (b). It also provides constructs, vectors, host cells, plant cells and Plants comprising the polynucleotides Chimeric promoters of the application.It also provides methods to modify gene expression and phenotype of plant cells and Plants by Transforming plant cells and plants with polynucleotides Chimeric Promoters. An example of a Chimeric promoter was produced by the combination of a sequence of Malus domestica) newest Kyara (b) with a sequence of Pyrus communis.
