Evidence for rare recombination at the gametophytic self-incompatibility locus [PDF]
Heredity, 2003 The gametophytic self-incompatibility locus has been thought to be a nonrecombining genomic region. Inferences have been made, however, about the functional importance of different parts of the S-locus, based on differences in the levels of variability along the gene, and this is valid only if recombination occurs.

Breaking self-incompatibility for diploid hybrid potato breeding: advances, mechanisms, and emerging technologies [PDF]
Frontiers in Plant SciencePotato (Solanum tuberosum L.) is a staple food crop vital to global food security. Conventional tetraploid potato breeding is severely constrained by tetrasomic inheritance, long breeding cycles, low propagation efficiency, and accumulated genetic load ...

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility
Journal of Horticultural Research, 2022 Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...

Pan-S-locus analysis reveals insights into the origin and evolution of self-incompatibility in the orange subfamily [PDF]
Genome BiologyBackground Self-incompatibility is controlled by a highly polymorphic supergene complex, the S-locus, which is structurally complex, rich in repetitive sequences, and varies in length from hundreds of kilobases to tens of megabases across different plant
