Abstract

Some agrochemicals have unique activities on plant, which modes of actions differ from those of herbicides and plant growth regulators. Because these induce useful and important phenotypic characteristics by activating physiological mechanisms in plant cell, understanding the underlying mechanism of their activities should be crucial for plant physiology and agriculture. As examples of such agrochemicals, studies on agrochemicals that activate the plant immune systems or root elongation, are described. Plant activators, inducers of systemic acquired resistance, were divided into two types, acting on upstream and downstream of salicylic acid (SA) biosynthesis, respectively. They have been useful research tools to clarify the regulation mechanism of SA-mediated disease resistance and to investigate another type of disease resistance mechanism mediated by brassinosteroids. By analyzing the roles of phytohormones in the isoprothiolane-induced root elongation indicated a positive effect of jasmonic acid and ethylene on primary root elongation. These types of research, categorized to one of chemical biology, would provide novel insight into plant physiology, which also contribute to control of crops.

农药对植物生理的调控研究。
一些农用化学品对植物具有独特的作用,其作用方式不同于除草剂和植物生长调节剂。由于它们通过激活植物细胞的生理机制来诱导有用且重要的表型特征,因此了解其活动的潜在机制对植物生理学和农业至关重要。作为此类农用化学品的例子,描述了对激活植物免疫系统或根伸长的农用化学品的研究。植物激活剂作为系统性获得性抗性的诱导剂,可分为两类,分别作用于水杨酸(SA)生物合成的上游和下游。它们为阐明sa介导的抗病调控机制和探讨油菜素内酯介导的另一种抗病机制提供了有益的研究工具。通过分析植物激素在异原硫烷诱导的根伸长中的作用,发现茉莉酸和乙烯对初生根伸长有积极作用。这些类型的研究,归类为化学生物学之一,将为植物生理学提供新的见解,这也有助于控制作物。
