Sorghum Derived Transcription Regulatory Elements Predominantly Active In Root Hair Cells and Uses Thereof

Transcription regulatory elements, namely promoter and terminator sequences, obtained from Sorghum bicolor that drive RNA transcription predominately in root hair cells, as well as cassettes, expression vectors, and genetically modified plants containing these transcription regulatory elements. The genetically modified plants can be gymnosperms, dicots, or monocots. Methods of directing transcription of a heterologous polynucleotide under control of these transcription regulatory elements in a genetically modified plant’s root hair cells are also provided.

Benefits

•  The transcription regulatory elements selectively direct gene expression in root hair cells of a plant

 

Applications

•  Overexpress transporters in root hairs to increase a plant's ability to extract nutrients from the soil or alternatively as a means of removing soil contaminants
•  Highly express secretory signal proteins in root hairs which would then be secreted into soil for collection
•  Use of root hair promoters to express gene products capable of synthesizing pesticidal compounds, which when secreted in soil would reduce the need for synthetic pesticide treatments
 
 
Benefits: 
  • The transcription regulatory elements selectively direct gene expression in root hair cells of a plant
