Abstract
The present application discloses a recombinant fiber-selective promoter region comprising a DNA molecule comprising a fiber specificity region of a cotton lipid transfer protein gene promoter, operably linked to a DNA molecule comprising a nucleotide sequence having at least 90% sequence identity to a nucleotide sequence of about 500 consecutive nucleotides of the 3′ end of the FB8-like 2 promoter and use thereof to increase fiber-selective expression of products of interest in cotton fiber cells.
Claims18
A recombinant DNA molecule comprising a chimeric promoter, which comprises in order:
- (i) a DNA molecule comprising a fiber specificity region of a cotton lipid transfer protein gene promoter comprising a nucleotide sequence having the nucleotide sequence of SEQ ID NO:
- 4, operably linked to
- (ii) a DNA molecule comprising a nucleotide sequence having about 500 consecutive nucleotides of the 3′end of the FB8-like 2 promoter of SEQ ID NO:
- 2, and wherein the chimeric promoter has the cotton fiber specific promoter activity of the synthetic promoter as set forth in SEQ ID NO:
- 1.
