発明の名称 (英語) METHOD FOR PRODUCTION OF STOLON-FORMING PLANT HAVING IMPROVED TUBER PRODUCTION ABILITY OR STOLON PRODUCTION ABILITY COMPARED WITH WILD TYPE, AND STOLON-FORMING PLANT PRODUCED BY THE METHOD UPDATE
発明の概要(英語) The present invention provides: a method for producing a stolon-forming plant having an improved tuber production ability compared with a wild type of the plant; and a stolon-forming plant produced by the method. The present invention also provides: a method for producing a stolon-forming plant having an improved stolon production ability compared with a wild type of the plant; a stolon-forming plant produced by the method; and a kit for improving the stolon production ability of a stolon-forming plant. This production method is a method for producing a stolon-forming plant having an improved tuber production ability compared with a wild type of the plant, and involves a step of introducing a Ran gene derived from Citrullus lanatus into a stolon-forming plant. This production method may additionally involve a step of introducing a polynucleotide encoding fructose-1,6-bisphosphatase/sedoheptulose- 1,7-bisphosphatase derived from a blue-green alga into the stolon-forming plant.
従来技術、競合技術の概要(英語) BACKGROUND ART
2008 Year is defined by the potato target Japan International potato years. According to Japan, year 20 therefrom, the mean value of the population of the world, 1 million or more each year and the predicted increased one by one, includes the world population growth and food shortage problem. 95% Or more in particular the increase tendency of the population, which causes in developed countries. Include one or potato such as potato, as well as the nutritional value of crops, such as a narrow land can be cultivated in the developing world in order to satisfy the cultivation conditions, has been widely spread activity. In India, 5-10 potato production beyond 2 year study to double, the sub-Saharan Africa potato production amount has been increased at a rate greater than any crop. In the future, it can be a potato consumption on an enlarged scale, many of them are cultivated in farms of developing countries leading to an increase of revenue, and create a potato are foodstuffs-security cover both sides of the revenue can be thought of crop.
However, these are achieved agricultural land area and given the current state is limited, per unit area of farmland crops (potato such as potato or the like for a) and yield, increased yield per individual plant of the crop that is required. Therefore, using gene recombinant technology up to now, the productivity of the crops per individual plant about improvement in a number of studies have been made.
For example, as a starting material for the synthesis of starch key enzyme SPS sucrose (sucrose phosphate synthase) gene introduced into the potato starch so as to enhance the metabolic function, potato tubers of the productivity of the edible part is 1.2 times so as to improve the non-patent Document 1 are disclosed. Potato ADK gene (adenylate kinase) also can be introduced so as to enhance the metabolic function of the starch, potato tubers of the productivity of the edible part is about 2 times so as to improve the non-patent Document 2 are disclosed.
On the other hand, the inventors have found that fructose - 1, 6 - bisphosphatase/sedoheptulose cyanobacterial derived from a gene encoding bisphosphatase - 1, 7 - tobacco introduced, in a chloroplast of tobacco by the expression of the gene, improve the function photosynthesis to promote growth of the plants is succeeded (see Patent Document 1).
In addition, the inventors have found that the roots of the plant or expand to a gene having a promoting activity (Ran gene), watermelon (Citrullus lanatus) from native botswana newly found that, by introducing the gene Arabidopsis thaliana Ran, promote extension of the roots of Arabidopsis thaliana are successfully acquired (see Patent Document 2).
