Provided is a method for the expression of a TGF-β in a plant. A chimeric nucleic acid sequence comprising: (1) a first nucleic acid sequence capable of regulating the transcription in a plant cell of (2) a second nucleic acid sequence, encoding a TGF-β, and adapted for expression in the plant cell; and (3) a third nucleic acid sequence encoding a termination region functional in said plant cell is introduced into a plant cell and the plant cell grown to produce TGF-β. The nucleic acid sequence may preferably be adapted for expression in a plant chloroplast. It is preferred that the TGF-β is TGF-β3, whether full length or in the form of an active fragment. |
