Alteration of plant self-compatibility using genetic manipulation of the s-genes

摘要

A method for altering self-compatibility/self-incompatibility in flowering plants is presented. The method comprises manipulation of the plant genome and production of the transonic plants. Abolishment of self-incompatibility was achieved by inserting into plant genome as DNA segment comprising anti-sense message of the allelic form of the S-gene responsible for self-incompatibility. This insert prove to be satisfactory to block expression of said allelic form of S-gene. Introduction of self-incompatibility was achieved by inserting into plant genome DNA construct comprising message coding for the S-protein responsible for self-incompatibility.
