Tapetum-specific promoters from brassicaceae spp

摘要

The present invention provides recombinant or isolated DNA comprising a promoter having tapetum-specific activity. The DNA encodes a promoter which naturally drives expression of (i) a gene encoding a 10.3 kDa tapetum protein in Brassica napus which gene hybridises under stringent conditions to the cDNA shown in figure 5; or (ii) a gene encoding a tapetum protein from Brassicaceae which gene hybridises under stringent conditions to the gene shown in figure 4, the gene shown in figure 7, the cDNA shown in figure 1 or the cDNA shown in figure 5.
