Title:
GENETIC MANIPULATION OF CONDENSED TANNINS
Document Type and Number:
WIPO Patent Application WO2004002215
Kind Code:
A3
Abstract:
The invention provides method and compositions for the modulation of condensed tannin production in plants. The methods of the invention allow creation of plants having novel phenotypes. Increased expression of condensed tannins in plants may be used to increase the nutritional value of food plants for both human and animal consumption. Increased condensed tannin content also reduces the potential for bloat in animals fed certain forage plants low in condensed tannin content. The invention may also be used to modify plant pigmentation.
