Plants experience different abiotic/biotic stresses, which trigger their molecular machinery to cope with them. Besides general mechanisms prompted by many stresses, specific mechanisms have been introduced to optimize the response to individual threats. However, these key mechanisms are difficult to identify. Here, we introduce an in‐depth species‐specific transcriptomic analysis and conduct an extensive meta‐analysis of the responses to related species to gain more knowledge about plant responses. The spider mite Tetranychus urticae was used as the individual species, several arthropod herbivores as the related species for meta‐analysis, and Arabidopsis thaliana plants as the common host. The analysis of the transcriptomic data showed typical common responses to herbivory, such as jasmonate signaling or glucosinolate biosynthesis. Also, a specific set of genes likely involved in the particularities of the Arabidopsis‐spider mite interaction was discovered. The new findings have determined a prominent role in this interaction of the jasmonate‐induced pathways leading to the biosynthesis of anthocyanins and tocopherols. Therefore, tandem individual/general transcriptomic profiling has been revealed as an effective method to identify novel relevant processes and specificities in the plant response to environmental stresses.

比较转录组学揭示了植物对节肢动物食草动物的反应中隐藏的问题

植物会经历不同的非生物/生物胁迫，这会触发其分子机制来应对。除了由许多压力引起的一般机制外，还引入了特定机制来优化对单个威胁的响应。但是，这些关键机制很难确定。在这里，我们将进行深入的物种特异性转录组分析，并对相关物种的反应进行广泛的荟萃分析，以获取有关植物反应的更多知识。将叶螨Tetranychus urticae用作单个物种，将几种节肢动物食草动物用作相关物种进行荟萃分析，并将拟南芥（Arabidopsis thaliana）植物是常见的宿主。转录组数据的分析表明，对草食动物具有典型的常见反应，例如茉莉酸信号或芥子油苷的生物合成。此外，还发现了一组可能与拟南芥-蜘蛛螨相互作用的特殊性有关的基因。新发现已经确定了茉莉酸酯诱导的途径相互作用中的重要作用，导致花青素和生育酚的生物合成。因此，已经揭示了串联的个体/一般转录组谱分析是鉴定植物对环境胁迫的反应中新的相关过程和特异性的有效方法。
