発明の名称 (英語) Alga, method for producing thereof and method for producing biomass by using the alga
発明の概要(英語) (TW201600602)
The productivity of biomass within the cells of algae can be improved by suppressing the expression of ATG8 in algae by (i) overexpression of MEX1 and/or (ii) silencing using miRNA, thereby providing algae having improved productivity of photosynthetic products, a method for producing said algae, a method for producing a biomass using said algae, and starch obtained by said algae.
特許請求の範囲(英語) [claim1]
1. Kinds live the archery target manufacture method, its use and datum compare, ATG8 displays the suppressed algae.
[claim2]
2. Like request item 1 lives the archery target manufacture method, its contains to the above algae illumination light light illumination step.
[claim3]
3. Like request item 1 or 2 live the archery target manufacture method, its use and datum compare, algae that in the chloroplast the bran bladder Gansu peptide density increases.
[claim4]
4. Like request item 3 live the archery target manufacture method, the above light illumination step is carries on materially the non-nitrogen hungry condition.
[claim5]
5. Like request item 4 live the archery target manufacture method, it does not contain the cell of stave cell stave step algae.
[claim6]
6. 1 kinds of algaes, it is datum compares, ATG8 displays the suppressed algae.
[claim7]
7. Like request item of 6 algae, MEX1 was displayed excessively.
[claim8]
8. Like a request item of 7 algae, it inducts has to code the MEX1 exogenetic multi-nucleotides.
[claim9]
9. Like request item of 8 algae, the above exogenetic multi-nucleotides are elect from below containing (a)-(c) the group one above: aminoacid sequence polypeptide multi-nucleotides that the (a) code contains the sequence identification number 1 or 3 showing;
(b) codes the following polypeptide multi-nucleotide: The aminoacid sequence that contains in the sequence identification number 1 either 3 showing has 1 or several aminoacid is deleted, the aminoacid sequence of substitution or increase, and maintains the function of MEX1 polypeptide;
(c) hybridizes under the strict condition with the following multi-nucleotides, and codes maintains the function of MEX1 polypeptide multi-nucleotides: Contains or (b) in the multi-nucleotides any multi-nucleotide supplementary basic group sequence multi-nucleotides with above (a).
[claim10]
10. Like request item of 6 algae, ATG8 gene by silent (silencing).
[claim11]
11. Like a request item of 10 algae, it inducts has: Basic group sequence miRNA that has sequence identification number 5 showing.
[claim12]
12. Like request item 6 to the 11 any 1 item of algae, it compare with datum, in the chloroplast the bran bladder Gansu peptide density increases.
[claim13]
13. 1 transformation algaes' manufacture methods, its contain to suppress the ATG8 performance of performance of ATG8 to suppress the step.
[claim14]
14. Like the request item of 13 transformation algaes' manufacture methods, its contain to make the bran bladder Gansu peptide density that in the chloroplast the bran bladder Gansu peptide density increases to increase the step.
[claim15]
15. 1 kinds of starches, it is use and datum compares, ATG8 displays the suppressed algae obtains.
[claim16]
16. Like a request item of 15 starch, it is the use and datum compares, the algae that in the chloroplast the bran bladder Gansu peptide density increases obtains.
