Title - CaMV 35S-enhanced mannopine synthase promoter and
method for using same
Claim 1
A DNA sequence comprising, in the 5' to 3' direction, a
first element linked to a second element, said first element
comprising an upstream activating region of CaMV 35S and said
second element comprising a mannopine synthase transcription
initiation region.
|
Claim 9
A chimeric promoter comprising a CaMV 35S enhanced mannopine
synthase promoter, wherein upon expression of a DNA sequence of interest in a
plant cell under the regulatory control of said promoter, said DNA sequence of
interest is expressible at a level of at least 5-fold higher than expression of
said gene of interest in a plant cell under the regulatory control of a CaMV 35S
enhanced CaMV 35S promoter.
|
Claim 16
A method to increase the expression of an expressible gene of interest under
the regulatory control of a mannopine synthase promoter
comprising the steps of:
providing a CaMV 35S
upstream activating region to the 5' end of a DNA sequence
comprising the mannopine synthase promoter; and
allowing said gene to be expressed.
|
The claims are generally directed to:
- A DNA sequence comprising (in 5' to 3' direction): an UAR of CaMV 35S and a
mas transcription initiation region.
- A chimeric CaMV 35S-enhanced mas promoter regulating the expression of a
gene of interest in a plant. The expression level is at least 5-fold higher than
the expression level achieved under the control of a CaMV 35S-enhanced 35S
promoter.
- A method to increase the expression of a gene of interest by using the
described chimeric promoter.
