発明の概要(英語) |
(EP2154246) It is intended to provide a polynucleotide comprising a viral base sequence, the viral base sequence containing: a first base sequence encoding a viral replication protein, and a second base sequence encoding a viral movement protein, the second base sequence being located downstream of the first base sequence and having a linking site for linking with an exogenous base sequence encoding a polypeptide to be expressed, the linking site being located downstream of the second base sequence, the second base sequence being obtained by modifying with a base sequence in a native sequence derived from a virus by insertion, substitution, or addition. By using this, a vector containing a viral base sequence is constructed, and a protein is efficiently produced without worsening growth of a host cell containing the vector. |

[claim1] 1. A polynucleotide comprising a viral base sequence, the viral base sequence containing: a first base sequence encoding a viral replication protein; and a second base sequence encoding a viral movement protein, the second base sequence being located downstream of the first base sequence and having a linking site for linking with an exogenous base sequence encoding a polypeptide to be expressed, and the linking site being located downstream of the second base sequence, the second base sequence comprising an inserted base sequence having a base length of 100 or more at any position from 17th base to 795th base of the base sequence shown in SEQ ID NO: 20, wherein a polynucleotide having the second base sequence is: (i) a polynucleotide having the base sequence shown in any one of SEQ ID NO: 4 through 17. [claim2] 2. The polynucleotide according to any one of claims 1, wherein the viral replication protein is: (i) polypeptides having amino acid sequences shown in SEQ ID NO: 1 and 2, respectively. [claim3] 3. The polynucleotide according to any of claims 1 or 2, wherein the virus belongs to a tobamovirus. [claim4] 4. The polynucleotide according to any of claims 1 to 3, wherein the virus is a tobacco mosaic virus or a tomato mosaic virus. [claim5] 5. A vector comprising a polynucleotide recited in any of claims 1 to 4. [claim6] 6. A plant comprising a polynucleotide recited in any of claims 1 to 4. [claim7] 7. A plant comprising a vector recited in claim 5. [claim8] 8. A transformant comprising a polynucleotide recited in claims 1 to 4. [claim9] 9. A transformant comprising a vector recited in claim 5. [claim10] 10. A method for producing a polypeptide, comprising: transforming or transfecting a plant with a polynucleotide recited in any of claims 1 to 4. [claim11] 11. A method for producing a polypeptide, comprising the step of: transforming a cell with a polynucleotide recited in any of claims 1 to 4. [claim12] 12. A kit for producing a polypeptide, comprising a polynucleotide recited in any of claims 1 to 4. [claim13] 13. A method for producing a polypeptide, comprising the step of: transforming or transfecting a plant with a vector recited in claim 5. [claim14] 14. A method for producing a polypeptide, comprising the step of: transforming a cell with a vector recited in claim 5. [claim15] 15. A kit for producing a polypeptide, comprising a vector recited in claim 5. [claim16] 16. A method for producing a polypeptide, comprising the step of: using a plant recited in claim 6 or claim 7. [claim17] 17. A method for producing a polypeptide, comprising the step of: using a transformant recited in claim 8 or claim 9. [claim18] 18. A kit for producing a polypeptide, comprising a plant recited in claim 6 or 7. [claim19] 19. A kit for producing a polypeptide, comprising a transformant recited in claim 8 or 9. |
