Detoxification of Tannins in Transgenic Plants

A novel genetic system for the elimination of tannins in edible plant materials such as canola seeds and sorghum seeds has been developed. This involves genetic engineering of these plants such that they accumulate a tannin-detoxifying agent. The Need Global agricultural production is greatly influenced by animal feeding technology, consequently there is a great need to improve the efficiency of animal feeding. The final yield of desired proteins expressed in transgenic plants is limited by tannin binding, hence there is a clear need for a method to prevent tannin binding and improve transgenic plant protein production for pharmaceutical and agricultural purposes. Potential Applications Tannin detoxification to improve live stocks' protein consumption and utilization from shoot and seed based animal feed Improvement of protein yield from transgenic plants by preventing formation of irreversible protein-tannin complexes

Advantages Improved cost effectiveness in

Animal feeds Transgenic plant protein production

Stage Canola seeds and sorghum seeds have been engineered to accumulate a tannin-detoxifying agent.
