Plants under herbivore attack emit distinct blends of herbivore-induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects. This concept of indirect plant defence has tremendous potential in sustainable insect pest control. It represents a cornerstone of alternatives to synthetic pesticides in integrated pest management (IPM) strategies. The composition of HIPVs determines the effectiveness of predatory insect attraction and is vulnerable to disturbance by multiple biotic and abiotic factors above- and belowground. Residues of the most widely used herbicide (glyphosate) are persistent pollutants in agricultural soils, where they increasingly affect plant physiology, with cascading effects on species interactions. Here, we tested whether herbicide legacy in soil affects plant performance, aphid herbivory, and aphid-induced volatile organic compound (VOC) emissions in oat plants, and tested whether the preference of predatory ladybirds towards aphid-infested plants is affected by herbicide legacy in the soil. Soil herbicide legacy reduced chlorophyll activity and plant height, but did not affect plant biomass nor aphid populations. Five compounds in the emitted VOC profile were significantly affected by soil history of herbicide use, which, in turn, affected ladybird orientation behaviour. In a choice assay, ladybirds preferred the odour of plants growing in herbicide-free soil. These results reveal a subtle layer of effects of herbicide legacy in soil on emission of HIPVs, with cascading effects on predatory insect behaviour. Our results demonstrate that essential ecosystem services in the aboveground plant space, such as natural pest control, may be reduced by soil pollution with anthropogenic pesticides such as glyphosate, causing mismatches in plant-insect communication.

迷迭香酸和其他咖啡酸和4-香豆酸衍生物广泛存在于陆地植物中。这些酚类化合物有助于植物的药用。然而，蕨类植物（Polypodiopsida）在酚类天然产物及其生物合成方面的研究仍然不足。采用LC/ESI-MS/MS和HPLC等方法，对3个亚科32种蕨类植物的咖啡酰5- o -奎宁酸、迷迭香酸及其相关化合物的含量进行了分析。我们从蕨类植物中纯化了一种未知的化合物，并通过NMR对其结构进行了鉴定，将其命名为blechnic acid B。所有被研究物种的提取物中均含有咖啡酰5- o -奎宁酸，而迷迭香酸仅在blechnae亚科B超支的4种（Doodia maxima, Lomariocycas tabularis, Neoblechnum brasiliense, Oceaniopteris ciliata）中发现。蓝衣酸B是蕨类植物中的一种新化合物，由异山梨酸（4′-羟基苯基乳酸）的两个部分组成。该木脂素仅在巴西新木脂素中检测到，并且与3种具有1个或2个3,4-二羟基苯基乳酸基团的木脂素相关。我们的研究表明，咖啡酰5- o -奎宁酸的生物合成基因已经在蓝藻科的祖先物种中建立。蓝衣酸B及其三个衍生物可能是通过迷迭香/异山梨酸单体在直接蛋白的帮助下选择性偶联而形成的。
