Self-incompatibility is one of the mechanisms that has evolved to encourage outbreeding in flowering plants (de Nettancourt, 1977). One particular type of self-incompatibility, gametophytic self-incompatibility, is found in members of Solanaceae, such as the wild tomato, Lycopersicon peruvianum (Mau et al., 1986). Gametophytic self-incompatibility in L. peruvianum is controlled by a single locu...

Self-incompatibility (SI) is a genetic mechanism in many flowering plants by which generative reproduction prevented. The self-incompatibility caused the functions of cell controlled genes called S or genes. results decreased pollination and ultimately yield loss. In apple (Malus domestica L.), multi-allelic S-locus. Approaches S-glycoprotein profiles allele-specific PCR methods using gene for ...

The S-locus-specific glycoprotein of Brassica and the gene encoding it (the SLG gene) are thought to be involved in determining self-incompatibility phenotype in this genus. It has been shown that the Brassica genome contains multiple SLG-related sequences. We report here the cloning and characterization of a Brassica oleracea gene, SLR1, which corresponds to one of these SLG-related sequences....

Specificity in the GSI response results from the S-haplotype-specific molecular interaction of S-locus F-box (SLF/SFB) and SRNase proteins in the self-incompatibility locus (S-locus). The answer to the question of how these two components of the S-locus (SRNase and SLF/SFB) interact has been gathered from several models. Since there is not enough evidence as to which one is the definitive model...
