発明の名称 (英語) PARASITIC PLANT GERMINATION REGULATOR コモンズ
発明の概要(英語) Provided are a compound having parasitic plant germination regulatory activity (especially parasitic plant germination induction activity), and a parasitic plant germination regulator in which said compound is used. A compound represented by general formula (1) [in the formula, R1 represents a group derived from a heterocycle containing a nitrogen atom; R2 represents a divalent group that is a linker; R3 represents an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted cycloalkyl group, or a C1-6 alkyl group; and R4, R5, and R6 are the same or different and represent a hydrogen atom, a halogen atom, an optionally substituted alkyl group, an optionally substituted alkenyl group, or an optionally substituted alkynyl group].
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 ') represented by the plant is parasitic, 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 for damage amounts are referred to as high.
Parasitic plant seeds, the soil can survive for a long period, of the secreted from the host in the vicinity of the root crop stimulation sensing (such as strigolactone) triggered, triggered by this, the parasitic capacitance to the root of the host plant. Then, appears on the ground or plant body generated by the parasitic or seed, the soil in the vicinity of the contamination. Therefore, once the seed of the plant soil parasitic contamination of and, if any countermeasures, the soil and plant parasitic followed by damage, soil contaminated seeds in the range and gradually expand.
As a countermeasure against parasitic plant, soil contaminated seeds parasitic to, plant germination modifier can be applied to the parasitic and said to be effective. For example, a host plant in an environment that there is no plant germination inducing agent can be applied to the parasitic, plant germination parasitic and parasitic and may not be dead, this soil purification. Therefore, parasitic plants development of more efficient induction material is demanded.
Strigolactone and its derivatives, for example, disclosed in Non-Patent Document 1. Is strigolactone, carotenoid derivative,
As represented by, a lactone ring tricyclic terpenoid (ABC ring) yet another to the lactone ring (the ring D) is coupled via an enol ether complex and is characterized by having a basic skeleton, many have asymmetric centers. Also, strigolactone and its derivatives, often present in the leachate the roots of the plant are known, such as branch to suppress the growth of plant hormones have the effect of (non-patent document 2).
Strigolactone and derivatives thereof having a basic skeleton compound is different, for example, disclosed in Patent Document 1. As shown in Patent Document 1 is a carbamate compound, 3-to induce in the carbamate mechirubutenorido obtained, as shown in Patent Document 1 the expression of the stimulatory activity of the germination requires a high concentration of 10μm, lower than the activity strigolactone and derivatives thereof are assumed to remain.
