Control of floral heteromorphy in Primula (Review)
Control of floral heteromorphy in Primula (Review)

The common primrose, Primula vulgaris, exhibits floral heteromorphy, with the two flower types being hermaphrodite and exhibiting reciprocal positions of male and female reproductive structures. Li et al. review progress towards identification and characterization of the S locus that controls this heteromorphy, and describe the development of new tools that will facilitate isolation and characterization of the S locus and its environs. Once S locus sequences are available for comparison, opportunities will present themselves for comparative studies of independently evolved systems that control development of different forms of flowers on plants of the same species.
