In 1923 five tubers and some seeds of Dahlia variabilis were obtained from Professor WEEVERS, from his garden in Ouddorp (Zeeland), the flower colour of which, according to his gardener, changed from red to white. The investigation begun with these was interrupted several times by circumstances for a shorter or longer period. The cultivation was, however, kept up, at any rate partially, by taking up the tubers every autumn, storing them in a frostproof house, and planting them in the spring. In…

Petal Color Is Associated with Leaf Flavonoid Accumulation in a Labile Bicolor Flowering Dahlia (Dahlia variabilis) ‘Yuino’
There were strong relationships between inflorescence color and leaf phenotype; red petal-producing plants accumulated flavonoids in leaves, whereas only bicolor petal -producing plants tended not to accumulate flavonoid in leaves.
Post-transcriptional gene silencing of CYP76AD regulates bract betalain biosynthesis in bougainvillea.
It is demonstrated that PTGS of BpCYP76AD1, one of the betalain biosynthetic enzyme genes, is responsible for the loss of betAlain biosynthesis in 'Thimma'.
Post-transcriptional silencing of chalcone synthase is involved in phenotypic lability in petals and leaves of bicolor dahlia (Dahlia variabilis) ‘Yuino’
Analysis of molecular mechanisms that are associated with petal color lability using the red-white bicolor cultivar ‘Yuino’ suggested that post-transcriptional gene silencing of DvCHS2 plays a key role in phenotypic lability in this bicolOR dahlia.
