Title: Self-incompatibility genes associated with the a10 allele
Inventor: ROTHSTEIN STEVEN J
IPC: C12N15/82
Filed: 1994-05-17
Abstract: Novel DNA molecules have been isolated that encode the S locus glycoprotein (SLG) and the S locus receptor kinase  (SRK)  of the A10 self-incompatibility allele. Surprisingly, the gene encoding the SRK-A10 protein was found to contain a one base pair deletion which would result in premature termination of translation and the production of a truncated SRK-A10 protein.  The defect in the  SRK-A10 gene  can  be  corrected  by  inserting  a nucleotide  at  position  948.     Expression  vectors comprising a corrected SRR-A10 gene can be used to produce a self-incompatible plant.
