(A) Schematic representation of L-morph (left) and S-morph flowers (right) and the classic model of corresponding S-locus genotypes, with the functions of individual genes indicated. Open ellipses represent anthers. The order of G, A and P at the S-locus is that suggested by Kurian and Richards (1997) for Primula sect. Primula; in Primula subgenus Auriculastrum the order appears to be GPA (Lewis and Jones, 1992). Also note that the positions of Gm and Pm relative to G and to P are unknown, respectively (indicated by a slash). (B) Schematic representation of three types of long homostyles and their S-locus genotypes arising from recombination within the S-locus (left), from mutation of the dominant G allele (middle), and from silencing the G and Gm genes (right). (C) Proposed model of the S-locus indicating the identity of CYP734A50 to the dominant G allele and its absence from the recessive haplotype.
