Abstract
DNA sequences are able to function as promoters of tissue-preferential transcription of associated DNA sequences in plants, particularly in the roots. These DNA sequences can be used in transformation vectors to produce transgenic plants which will express the heterologous genes preferentially in tissue, particularly in the roots of maize plants.
Claims6
A recombinant DNA vector, which is pCIB 1318.
A chimeric gene comprising:
- a) the promoter sequence located at nucleotide positions 1 to 2564 of the gene set forth in SEQ ID NO:1;
- b) a coding sequence of interest;
- and
- c) a 3' terminal sequence;
- wherein said promoter sequence directs the transcription of said coding sequence.
2 more elements
An isolated nucleotide sequence comprising the promoter sequence located at nucleotide positions 1 to 2564 of the gene set forth in SEQ ID NO:1.
