Ubiquitin promoters from rice and sugarcane

Apart from patents on the ubiquitin regulatory system from maize, there are also patents specifically claiming ubiquitin promoters from rice and sugarcane.

The Board of Supervisors of Louisiana State University and Agricultural and Mechanical College holds a United States patent (US 6528701) on rice ubiquitin promoters. This patent claims a rice ubiquitin promoter and a method for using it in controlling gene expression in plants. It shows in the description that the rice ubiquitin promoter is stronger than the maize ubiquitin promoter in driving gene expression in rice.

United States of America as represented by the Secretory of Agriculture & University of Hawaii has three United States patents (US 6706948, US 6686513 and US 6638766) on sugarcane ubiquitin promoters (UBI4 and UBI9).

 Title – Rice ubiquitin-derived promoters

Claim 1
An isolated nucleotide sequence comprising a rice ubiquitin promoter capable of controlling constitutive expression of a nucleic acid encoding a polypeptide, wherein said nucleotide sequence comprises at least a portion of SEQ ID NO:3 which is upstream of position 2785 and wherein said portion retains promoter activity.

The claims of this patent are generally drawn to:

  • An isolated nucleotide sequence comprising a rice ubiquitin promoter (upstream of position 2785 of SEQ ID NO:3) , and
  • A method of expressing a heterologous nucleic acid sequence encoding a polypeptide in a plant or in its progeny under the control of the rice ubiquitin promoter (claim 6).
