Abstract

The invention relates to the isolation of promoters from corn capable of directing transcription of an operably linked foreign DNA sequence preferentially, selectively or exclusively in the roots of plants, such as corn plants. The invention also relates to the use of chimeric genes for the preferential or selective expression of biologically active RNA of interest in the roots of plants, such as corn plants. Plants, such as corn plants, comprising corn root preferential or selective promoters operably linked to a foreign DNA sequence which, upon transcription, yield biologically active RNA preferentially or selectively in the roots of plants are also provided.
