発明の名称 (英語) STRIGA GERMINATION REGULATOR UPDATE コモンズ
発明の概要(英語) A Striga germination regulator is provided, an active ingredient therein being a compound having a different basic skeleton from strigolactones and derivatives thereof. The Striga germination regulator contains the compound represented by general formula (1) or a salt, hydrate or solvate thereof.
従来技術、競合技術の概要(英語) BACKGROUND ART
Which belongs to the genus striga (as used herein, may be referred to as' striga ') is, corn, rice, peas and the like are main parasitic crops, growing failure.The resulting, Africa, Asia, Australia, America and the range or the like, particularly in Africa, 100 million US dollars each year the amount of damage is called up.
Striga seeds, the soil can survive for a long period, of the secreted from the host in the vicinity of the root crop sensing strigolactone, triggered by this, the parasitic capacitance to the root of the host plant.Then, appears on the ground of the seed produced by plants striga, also in the vicinity of the contamination of the soil.Therefore, once the seed of the soil and contaminated striga, if any measures, that is followed by a damage of the soil and striga, the contaminated soils and seed range and gradually expand.
As a countermeasure against striga, soil contaminated seeds striga, germination striga (induction or suppression) to adjust the effective application of the agent is called.For example, a host plant germination striga environment not if the application of the inducing agent, can be germinated striga is not dead and thus the parasitic, which can be purified by the soil.In addition, if the application of the germination inhibitors striga, without parasitic striga host plant cultivation can be achieved.Therefore, the germination striga more efficiently induce or suppress the development of materials has been demanded.
Heretofore, strigolactone striga germination and derivatives thereof as the active ingredient is developed to adjust the (non-patent document 1), from the viewpoint of the stability and the synthetic cost, has not been put into practical use.
In addition, in the case of the development of modulators of germination striga, typically, is applied to the material of the seed candidate striga, the germination rate of change in index induced by, as a regulator of the germination striga test the validity (non-patent document 2).However, such a test, one of the candidate 1 to test the validity of the material, the preparation of the seed, such as measurement of the number of germination, it takes much time and effort, a number of candidate materials is difficult in a high throughput processing.In addition, if seed striga, plant seeds at the import via the permission of the epidemic prevention is necessary, the experimental space can be used only in authorized is a problem.Further, the germination index as the compound can be identified and, if the target protein is not clear, it is possible to improve through rational design difficult.
