Abstract
A method for extraction of heterologous protein from monocotyledonous plant seed comprises extracting the germ portion of the seed and extracting and purifying the protein from the germ. Enhanced expression in the germ is provided, and allows for improved efficiency in production, and cost savings. Directing expression to the germ portion further increases expression levels of the protein. The ubiquitin promoter preferentially directs expression to the germ portion of plant seed.
