The plant has become the factory for Intrinsic Factor.
Arabidopsis thaliana or thale cress, which is a member of the mustard family is the plant chosen to be the IF factory. This plant is the most widely studied plant in botany and its genetic code is well understood and is a natural host for the human IF gene.
The 'transformed' plant was developed at the University of Aarhus in Denmark and was successfully grown in conventional greenhouses. After Xeragenx acquired the exclusive global rights to the patented technology, the seeds from these transformed Arabidopsis plants were imported into the US and are now grown under contract by a world-class plant biosciences company providing scalability for global commercial supply.
