self incompatibility

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