Abstract
A Brassica sp. genomic clone G 363 containing a gene promoter, which directs expression in the stigma, was isolated. Based on microbombardment studies of Brassica napus flowers with the gene Pis 63/Gus fusion, the Pis 63 promoter was shown to direct GUS expression to the stigma. This promoter will be useful for the temporal and spatial control of gene expression in plants.
