UV-microscopic and chromatographic studies have been performed on the variation in contents and configuration of the flavones present in epidermal cells of the petals, stem leaves, rosette leaves and cotyledons ofSilene pratensis plants. Most of the

The expression of the allelic isovitexin 7-O-glycosylation genes gG (transfer of glucose) and gX (transfer of xylose) was studied in cotyledons, rosette leaves, stem leaves and petals of Silene plants. These studies revealed that gG is expressed in a

The flavones present in three European species of Silene section Elisanthe (Silene diclinis, S. heuffelii and S. marizii) have been identified. The flavones of these species were compared with the flavones present in the three remaining species of se

The variation in flavone glycosylation patterns inSilene is the result of the expression of six genetic loci, which control either the presence of allozymes differing in substrate specificity or isozymes regulated differently during development. Sero

Two further loci can be added to the three already known (g, gl and fg) in Silene controlling the 7-O and 2″-O-glycosylation of the C-glycosylflavone isovitexin (6-C-glucosylapigenin). These loci, O7g for the 7-O-galactosylation and D6a for the 2

Two isovitexin glycosides have been found in the cotyledons and foliage leaves of Sitene pratensis plants that are unable to glycosylate isovitexin in their petals (genotype gg glgl fgfg). The glycosides (isovitexin 7-O-galactoside and isovitexin 7-O

The 7-O- and 2"-O-glycosylation of the flavone isovitexin (6-C-glucosylapigenin) in the petals of Silene plants is accomplished by allozymes which differ in their specificity toward the sugar to be transferred. The g locus controls the 7-O-glycosylat

The isovitexin-O-glycosylation patterns of rosette leaves, stem leaves and petals of Silene dioica plants were investigated. The 7-O -xylosylation of isovitexin, controlled by gene gX, only occurs in the petals. In the leaves isovitexin is 7-O -galac

Enzyme activity responsible for the biosynthesis of isovitexin-7-O-galactoside from isovitexin and UDP-galactose can be demonstrated in protein extracts of cotyledons and rosette leaves from Silene pratensis plants. This galactosyltransferase activit
