Distyly supergene
A supergene, called the self-incompatibility (or S-) locus, is responsible for the occurrence of distyly. The S-locus is composed of three tightly linked genes (S-genes) which segregate as a single unit. Traditionally it was hypothesized that one S-gene controls all female aspects of distyly, one gene that controls the male morphological aspects, and one gene that determines the male mating type. While this hypothesis appears to be true in Turnera, it is not true in Primula nor Linum. …

WebEarlier ideas on the genetic architecture of the S-locus supergene governing distyly have recently been overturned by discovery that the dominant S-haplotype is a hemizygous region absent from the s-haplotype. Ecological, phylogenetic and molecular genetic data have validated some features of theoretical models on the selection of the polymorphism. WebDec 1, 2024 · Distyly, a floral dimorphism associated with heteromorphic self-incompatibility and controlled by the S-locus supergene, evolved independently multiple times. Comparative analyses of the first transcriptome atlas for the main distyly model, Primula veris, with other distylous species produced the following findings.
