Abstract

Studies of homeotic mutations after floral organ in Antirrhinum and Arabidopsis have led to the ABC model of flower development. This model is a simplified view of the complex interactions between MADS box organ-identity genes that co-ordinate flower development. Numerous floral homeotic mutants of Primula are available as commercial varieties and as horticultural sports from National Collections. Many of the mutants show homeotic phenotypes not found in other plants. We have obtained three Primula mutants, Hose-in- Hose, Thickened Petals, and Sepaloid that are all defective in petal development. We will define the dominance, complementation, and epistatic relationships of these mutants. In parallel we will isolate and characterise wild type and mutant alleles of Primula B function genes for a molecular definition of these mutations.
