Definition

  • [W. Y. Cheung] Self-incompatibility (SI) in Brassica is a sporophytic system, genetically determined by alleles at\ \ the S-locus, which prevents self-fertilization and encourages outbreeding... , "[M. Watanabe] Self-incompatibility (SI) in Brassica species is an elaborate system preventing self-fertilisation.\ \ It is important for high-quality seed production in Brassica vegetables, such as cabbage, turnip and\ \ Chinese cabbage. In classical genetics, Brassica SI is sporophytically controlled by a single\ \ S-locus with multiple alleles. This concept of the S-locus enabled us to beginmolecular studies to\ \ determine how the SI system is regulated... , "[Shutian Li] Self-incompatibility (SI) in higher plants is an important mechanism to prevent inbreeding and\ \ involves specific rejection of incompatible (''self'') pollen. In\ \ field poppy (Papaver rhoeas), S proteins encoded by the stigma component of the S-locus interact\ \ with incompatible pollen, resulting in cessation of tip growth... , "[Daniel P. Matton] Self-incompatibility (SI) in angiosperms is a genetic mechanism that promotes outcrossing through\ \ rejection of selfpollen. In the Solanaceae, SI is determined by a multiallelic S locus whose only\ \ known product is an S RNase. S RNases show a characteristic pattern of five conserved and two\ \ hypervariable regions... , "[Kristina Edh] Self-incompatibility (SI) in plants is a classic example of a trait evolving under strong\ \ frequency-dependent selection. As a consequence, population genetic theory predicts that the S\ \ locus, which controls SI, should maintain numerous alleles, display a high level of nucleotide\ \ diversity, and, in structured populations, show a lower level of among-population differentiation\ \ compared to neutral loci...
