Increase of Foreign Gene Expression in Monocot and Dicot Cells by an Intron in the 5′ Untranslated Region of a Soybean Phosphoenolpyruvate Carboxylase Gene

抄録

  A genomic clone containing part of the coding region and upstream sequences of a phosphoenolpyruvate carboxylase (PEPC) gene was isolated from a soybean genomic library. The first intron of this gene is located in the 5′ untranslated region. This intron-spanning fragment is capable of increasing GUS activity in plant cells.
