A method for the production of a human protein in plant, in particular of a human recombinant lysosomal enzyme in a plant endosperm, comprising: - a first step of plant transformation whereby the protein is obtained and confined in an endosperm, which is not eventually absorbed by the embryo, and the presence of large quantities of the protein in the endosperm does not negatively affect seed viability and germination speed; - the use, in the first step of plant transformation, of an endosperm-specific promoter upstream the gene encoding said protein, and of a signal peptide for a co-translational transfer of the newly synthesized protein into the lumen of the endoplasmic reticulum of the endosperm cells for its tissue-specific accumulation; - a second step of protein accumulation inside the seed endosperm of a plant. |
