Chimeric plant promoters and their uses in plants

摘要

The present invention provides novel promoters for use in plants. Specifically, the present invention provides novel chimeric promoters comprising combinations of plant enhancer elements and plant promoters. The present invention also provides DNA constructs; transgenic cells, plants, and seeds containing these novel chimeric promoters; and methods for preparing and using the same.

主权项

1. A DNA molecule comprising a chimeric promoter sequence comprising, as operably linked components:
a) a first DNA sequence comprising:
i) SEQ ID NO:33; orii) a DNA sequence with at least 95 percent sequence identity to SEQ ID NO:33 having promoter activity; orii) a fragment comprising at least 50 contiguous nucleotides of SEQ ID NO:33 having promoter activity; and b) a heterologous DNA sequence comprising:
i) SEQ ID NO:10; orii) a DNA sequence with at least 95 percent sequence identity to SEQ ID NO:10 having enhancer activity; orii) a fragment comprising at least 50 contiguous nucleotides of SEQ ID NO:33 having enhancer activity.
