Le Rouge et le Noir: Where the black dahlia gets its color
The molecular mechanisms whereby a spectrum of dahlias, from white to
yellow to red to purple, get their colour are already well known, but
the black dahlia has hitherto remained a mystery. Now, a study published
in BioMed Central's open-access journal BMC Plant Biology reveals for
the first time that the distinctive black-red colouring i
s based on an increased accumulation of anthocyanins as a result of drastically reduced concentrations of flavones.
Dahlia variabilis hort. is a popular garden flower. Continuous dahlia
breeding worldwide has led to the availability of a huge number of
cultivars 20,000 varieties many of them showing red hues. However,
black hues of dahlia flowers occur rarely, in comparison. Credit: Dr.
