Abstract

The invention provides methods and compositions for the modulation of proanthocynidin (“PA;” condensed tannin) production in plants. The methods of the invention allow creation of plants having novel phenotypes, such as alterations in levels of PA or in the types of tissues in which PAs are produced. Altered expression of PA in plants may be achieved, for instance without significantly affecting anthocyanin content or overall secondary metabolite profiles. Alternatively, expression of PA in plants may be achieved while also affecting anthocyanin content.
