The present invention relates to a method for preparing transformed plants
expressing thyroid stimulating hormone receptor In particular, the
present invention relates to a method for preparing transformed plants
expressing (hTSHR) or (hTSHR-ECD) which comprises the steps of: (a)
transforming plant cells with the following polynucleotide sequences: (i)
a polynucleotide sequence encoding hTSHR or hTSHR-ECD; (ii) a promoter
that functions in plant cells to cause the production of an RNA molecule
operably linked to the polynucleotide sequence of (i); and (iii) a
3'-non-translated region that functions in plant cells to cause the
polyadenylation of the 3'-end of said RNA molecule; (b) selecting
transformed plant cells; and (c) obtaining transformed plant by
regenerating said transformed plant cells, transformed plants and a
method for preparing hTSHR or hTSHR-ECD.
