 Title    The Coloration of Gladiolus I. Survey of Anthocyanins in Petals of Gladiolus  
 Abstract    The six common anthocyanidins found in Gladiolus petals occur in four types o f glycosilation: 3-glucoside, 3-rhamnoglucoside, 3,5-diglucoside, and 3-rhamnoglucoside-5-glucoside. The six monoglucosides appear in minute quantities, whereas any of the other 18 anthocyanins can serve as the m ajor contributor to the coloration of Gladiolus petals. In high performance liquid chrom atographic analyses of petal pigm ent composition o f nine cultivars, it was found that the anthocyanins are grouped on the basis of the aglycon substitution. Thus, pelargonidin appears by itself (group I), cyanidin and peonidin constitute group II, and delphinidin, petunidin, and malvidin group III.

 Title    Genetic Control of Chalcone Synthase Activity in Flowers of Matthiola incana  
 Abstract    Chalcone synthase activity was demonstrated in enzyme preparations from flowers o f defined genotypes of Matthiola incana (stock). The product formed from 4-coumaroyl-CoA and malonyl-CoA was naringenin and not the isomeric chalcone, because chalcone isomerase was also present in the reaction mixture. Chalcone synthase activity could be detected only in flower extracts o f genotypes with wild-type alleles at the locus f Thus, the interruption of the anthocyanin pathway in white flowering lines with recessive alleles (ff) of this gene is clearly due to a lack o f this enzyme activity. Independent on the genetic state of the locus b which controls the formation of pelargonidin or cyanidin, respectively, in the flowers, 4-coumaroyl-CoA was the only suitable substrate for the condensation reaction.

 Title    Anthocyanin Carrying Structures in Specific Genotypes of Matthiola incana R. Br  
 Abstract    Several lines of the genetically well defined Matthiola incana (Brassicaceae) concerning the anthocyanin biosynthesis (line 02, 06, 10, and 14) store the anthocyanin pigment as crystals (line 06) or in anthocyanoblasts ("balls") in the epidermal cells (line 02, 10, and 14) o f the flower petals. The genetic constitution o f these genotypes is in addition to the basic factors f +, g+, and e+, b+b+ or bb (cyanidin or pelargonidin type), 11, u+u+, and v+v+ or vv, demonstrating that the 11, u+u+ constitution is responsible for precipitation of anthocyanins in a certain structure indepen­ dent of the other modificationally acting genes b and v. The 11, u+u+ types accumulate preferentially acylated 3-biosides.
