| Abstract: | Tobacco was transformed with a gene coding for an S-locus-specific glycoprotein of Brassica oleracea. The resulting transgenic plants showed tissue-specific and developmentally regulated expression of the introduced gene. Immunolocalization experiments showed that the Brassica gene was expressed in the stylar transmitting tissue of the transgenic plants. The pattern of expression of the introduced gene was more similar to that of the S-associated genes of Nicotiana alata than to expression in Brassica. Self-incompatibility was not conferred by the introduced gene. |
