| Outline of Final Research Achievements |
The grasses (Poaceae) possess a unique self-incompatibility system controlled by two unlinked loci S and Z. This study aimed to isolate and identify an unknown pollen (male) S gene in a wild species of barley (Hordeum bulbosum). Informatics analysis using orthologous sequences of the already-identified pistil (female) S gene successfully delimited the genomic region homologous to the S locus on the barley and wheat chromosomes. Among the H. bulbosum orthologs residing within the delimited region, a promising pollen S gene candidate was finally identified based on physical linkage to the female S gene, sequence polymorphisms and preferential expression in the pollen.
