Abstract: The present invention is to provide a recombinant construct for transforming a plant comprising a DNA sequence encoding a recombinant human cytokine and a promoter capable of directing the expression of the recombinant human cytokine in the plant. The present invention is also to provide a method for constructing a transgenic plant, comprising the steps of transforming a plant cell with a recombinant construct of the invention, and regenerating the transgenic plant from the plant cell to produce recombinant human cytokine, for example, human granulocyte colony stimulating factor (hG-CSF), in seeds of the transgenic plant. The plant production method of the invention thus has a promising potential to mass-produce some of the most expensive biopharmaceuticals of restricted availability in a much cheaper way, which has high economic value for disease therapy, diagnosis and prevention, and is more accessible to the less affluent countries.
