    Research progress on molecular design and conduction distribution mechanism of guided pesticide

    • 摘要: 导向农药是指可在植物体内向特定部位定向传导的农药。通过改善外源物质的传导性 (尤其是韧皮部传导性) 可显著提高导向农药在植物体内的系统性分布,有利于实现精准防控。文章综述了导向农药的分子设计理念、糖基导向农药和氨基酸导向农药的韧皮部传导性及生物活性等方面的研究进展,指出农药分子与相关氨基酸转运蛋白载体之间的构效关系将是今后导向农药研究的重点,同时提出可以激发子作为导向基团,研究开发既能在植物体内通过韧皮部传导防治病虫害,又能激活寄主防御反应、具有植物激活剂性质的新型导向农药的思路。

       

      Abstract: Guided pesticide can directionally translocate and accumulate to specified parts in plants. Improving the conductivity of xenobiotics can dramatically enhance systematic distribution of plants to achieve precise control. In this work, the idea of molecular design of guided pesticide was reviewed, as well as research progress on sugar guided pesticide and amino acid guided pesticide regarding its phloem translocation and biological activities. It is pointed that the structure-activity relationship (SAR) between pesticide molecules and relevant amino acids transporter would be a research focus for the next few years. In addition, a novel guided pesticide taking elicitor as guided group and possessing properties of plant activator is put forward to develop, which not only can control plant pests by phloem translocation but also activate defense reactions of host.
