発明の名称 (英語) TRANSGENIC PLANT EXHIBITING ENHANCED GROWTH AND METHOD FOR PRODUCING SAME NEW
発明の概要(英語) The present invention addresses the problem of providing a plant which exhibits an enhanced growing ability compared to plants produced by conventional methods, by establishing a method for producing a transgenic plant which exhibits an enhanced growing ability. A transgenic plant which exhibits a growing ability which is enhanced compared to that of the host plant, and has a chimeric protein of a peptide containing an amino acid sequence derived from a motor domain of myosin XI of a donor plant 1, which is a plant species other than the host plant, and a peptide containing an amino acid sequence derived from a domain other than the motor domain of myosin XI of a donor plant 2, which is the host plant or a plant species other than the host plant, the transgenic plant being characterized in that the motor domain loop 2 region has EEPKQGGKGGGKSSFSSIG or EEPKQGGGKGGSKSSFSSIG, and in addition to these sequences, has an amino acid sequence in which multiple amino acids have been deleted, replaced or added.
従来技術、競合技術の概要(英語) BACKGROUND ART
Techniques to promote the growth of plants, plant biomass and thereby increases the amount, agricultural, forestry and biomass energy industry is very important. Thus, for example, the optimization of the cultivation conditions, the processing by the plant hormone, modification of an endogenous gene, by the introduction of an exogenous gene, knock-out transgenic plant or plant such as making various attempts have been made.
By the introduction of foreign genes in transgenic plants is an invention relating to the size of the (non-patent document 1, 2). In many cases, the size of the conventional technology of the tobacco plant, Arabidopsis thaliana, rice, corn has been introduced to the foreign gene, for example, described in Non-Patent Document 1 and 2 such as a gene encoding a protein involved in photosynthesis path is. However, such a combining method of the size of the plant due to enhancement of the path may be problematic. It is, it is possible to improve the ability of the coupling leaves even if, and only a limited effect on the entire plant is not exhibited. Further, as a result of combining the product stored in the leaves, is an improved ability to photosynthesis, the feedback effect decayed over time.
The inventors of the present invention, plasma flow rate that will cause the rate of growth in the plant cell is presumed, having plant cells of the actin cardiomyosin XI focused on the rate of motion to motion. Of actin-myosin (Chara corallina) on the movement speed is very fast. Further, experimental plant models, genetic and physiological characteristic has been solved from a portion, is in monocots (Brachypodium distachyon) minato wheat grass, in dicotyledonous plant Arabidopsis (Arabidopsis thaliana) been used (Non-Patent Document 3, 4). Therefore, the inventors of the present invention, and is selected as the host plant Arabidopsis thaliana minato wheat grass, these motor domain other than domain cardiomyosin XI, XI to the donor domain assessing the plant is selected as the motor, the motor of the combination of assessing the XI domain expression of the chimeric proteins for the purpose of the host plant, the gene encoding the chimeric protein can be introduced into the host plant attempted. As a result, for both Arabidopsis and minato wheat grass, compared to the wild-type growth is enhanced and the size of the transformed plant production (Patent Document 1) has succeeded.
