ABSTRACT:
DNA sequence of S-genes which encode S-proteins and control the self-incompatibility reaction in gametophytic self-incompatible plants have been identified. The DNA sequence encoding several S-proteins of N. alata and their attendant signal sequences are specifically provided. Regulatory sequences which direct expression of the S-genes in reproduction tissue of self-incompatible plants have also been identified. A method for the identification and isolation of cDNA and genomic DNA coding sequences of the S-genes is described.
