Control genes are of many forms. Turning off and on is usually in
control of promoter genes.
Flavanoid is not an either/or situation with antrocyanin. But
reduction of antrocyanin can leaf more precursors to be available for
flavanoid chain reaction.
Ae inclusions are inside vaculole.

I dug around in the archives and found this (from you, Chuck).
<The water soluble yellow is a flavanoid. While anthocyanin and
flavanoid share some of the initial biochemistry chain they
differentiate quite early in the chain>
So does that mean that it has flavanoids in the vacuoles instead of
anthocyanin? Can't have both?
How in the world does a plant 'know' to use precursors to make one
pigment in the vacuole, but go a different direction in the Ae
inclusions? very smart plants!
