METHODS AND COMPOSITIONS FOR THE EXPRESSION OF A POLYNUCLEOTIDE OF INTEREST

摘要

Methods and compositions for expressing a polynucleotide of interest are provided. Compositions comprise an enhancer domain set forth in SEQ ID NO: 1, 10, 15, or 16 and active variants and fragments thereof. Further provided are DNA constructs comprising at least one transcriptional enhancer sequence comprising the nucleotide sequence set forth in SEQ ID NO:1, 10, 15, or 16 or an active variant or fragment thereof, operably linked to a heterologous promoter. Such chimeric transcription regulatory regions can be operably linked any polynucleotide of interest. Further provided are cells, plants, plant parts, and germplasm comprising the DNA construct. Methods of using the chimeric transcriptional regulatory region are also provided. In specific embodiments, methods of expressing a polynucleotide of interest, including for example, sequences that confer tolerance to herbicides, and methods to select a cell having the DNA construct are provided.
