  摘要：

  噻唑和苯氧乙酸是许多天然和合成生物活性剂中的关键部分。设计合成了一系列 N-（5-（3,5-甲氧基苯基）-（噻唑-2-基））苯氧基乙酰胺衍生物 6an–6bd，并通过 NMR 和 HRMS 证实了它们的结构。通过培养皿生物测定，大多数衍生物对 Echinochloa crusgalli （E.c.） 和 Lactuca sativa （L.s.） 种子萌发表现出优异的抑制作用。事实上，除草剂生物测定表明，6an（2-（2,4-二氯苯氧基）-N-（5-（3,5-二甲氧基苯基）-1,3,4-噻二唑-2-基）乙酰胺）对L.s.的抑制作用最好（IC50 = 42.7 g/ha，田间实验为 375 g/ha）。6an 在 2 至 4 倍的田间使用量对 Zea mays 也没有有害影响。此外，转录组学和代谢组学分析显示，6an 显著影响细胞代谢，包括半乳糖代谢以及抗坏血酸和积石酸盐代谢。这些发现突出表明

  Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera

  摘要：

  Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera. (C) 2015 Elsevier Ltd. All rights reserved.
