Abstract
The object of the invention is to provide a plant body in which the program for accumulating storage products has been modified, and applications of the same. In the invention, the plant body is constructed so as to have a B3 DNA-binding domain and an EAR motif, and so as to be capable of repressing the expression of two or more genes which code for two or more proteins having a sugar-inducible promotor function-suppressing activity.
Claims20
A plant body configured to suppress a function of a sugar-inducible sweet potato sporamin minimal promoter by repressing expression of at least a first protein and a second protein, wherein:
- the first protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 2, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 1;
- the second protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 4, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 3;
- and
- the plant body accumulates a storage product at a site other than a normal storage organ by sugar induction.
A plant body production method comprising a step of manufacturing a plant body configured to suppress a function of a sugar-inducible sweet potato sporamin minimal promoter by repressing expression of at least a first protein and a second protein, wherein:
- the first protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 2, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 1;
- the second protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 4, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 3;
- and
- the plant body accumulates a storage product at a site other than a normal storage organ by sugar induction.
A plant storage product production enhancer comprising one or two or more nucleic acid construct, wherein the enhancer suppresses expression of at least a first protein and a second protein, wherein:
- the first protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 2, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 1;
- the second protein comprises a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 4, or is encoded by a sequence having at least 95% homology to the sequence set forth in SEQ ID NO:
- 3.
