Abstract
The concerted action of two flavone-skeleton modifying genes, P and Me, and the alleles of three independently segregating loci g, gl and fg involved in flavone-glycosylation lead to the 33 different flavones so far identified in Silene. The alleles of the different loci involved in flavone-glycosylation control enzymes which differ in substrate specificity, a phenomenon not often described in higher organisms. The alleles of the different loci are variously distributed over the different species. The possible evolutionary implications of these distributions are discussed.Keywords
