> Dear netters,
> After reading a paper by Michael Witty about Thaumatin II reporter
> gene utilisation in plant genetic manipulations (which appeared in
> Methods of Enzymology 216: 441-447, 1992), one particular paragraph
> at the Concluding Remarks section (p. 447) made me curious.
> At the final paragraph, the author mentioned  a phenotypic change in
> plants overexpressing the Thaumatin II under the control of CaMV35S,
> and continued to state that this phenotypic change could be used to
> detect transgenic lines or whole plants.
> Could someone inform me what this phenotypic change is all about?
> Is it a color change or more on the morphology level?
> With my best regards,
> Dr. Sertac Onde

 I would also be interested in the answer to this question.
