Effect of UTRs from TMV-RNA on the expression of foreign gene in transgenic plants

摘要

To investigate the effects of 5' and 3' untranslated region (UTR) from tobacco mosaic virus (TMV) on expression of foreign genes, four plant-expression vectors pBG437, pBG438, pBG440 and pBG440ΔNOS containing expression cassettes of GUS-NOS; Ω-GUS-NOS, Ω-GUS-3' UTR-NOS and Ω-GUS-3' UTR downstream of CaMV 35S promoter with double Enhancer sequences respectively have been constructed.
