草食动物的身份和强度对于介导植物防御反应很重要，但它们之间的相互作用对植物代谢组的影响尚未得到充分探索。本研究采用气相色谱质谱法检测了不同强度的咀嚼型Laelia coenosa和茎刺吸型Dimorphopterus pallipes组合侵染芦苇叶、茎和根的代谢变化。监督偏最小二乘判别分析表明，这两种昆虫的摄食明显改变了所有植物组织的代谢特征。此外，两种食草动物的不同强度导致叶子中的代谢物显着不同。只有高强度D． pallipes激活了根中独特的代谢特征，而茎代谢物对不同食草动物强度的反应没有差异。仅在高食草动物强度侵染的叶子中检测到两种食草动物对植物代谢组成的显着联合取食影响。一般来说，D.与L相比，pallipes喂养对不同组织中代谢物含量的影响更强。共同安全教育。叶代谢物的响应与草食动物强度之间大多呈线性关系，而根代谢物通常对草食动物强度表现出非线性响应。此外，两种食草动物同时取食叶子时存在显着的相互作用，往往是拮抗的。总的来说，我们的研究表明，植物对食草动物的反应因组织而异，并且根据食草动物的身份和强度而受到不同的影响，这可能会在整个植物水平上对植物代谢物的相互作用有所不同。
Herbivore identity and intensity are important in mediating plant defense responses, but the effects of their interaction on the plant metabolome have not yet been fully explored. Here, gas chromatography mass spectrometry was utilized to detect the metabolic changes in leaves, stems and roots of the common reedPhragmites australisinfested with different intensity combinations of leaf-chewingLaelia coenosaand stem piercing-suckingDimorphopterus pallipes. The supervised partial least squares-discriminant analysis showed that feeding by the two insects distinctly changed the metabolic profiles of all plant tissues. Furthermore, different intensities of the two herbivores resulted in significantly different metabolites in leaves. Only a high intensity ofD. pallipesactivated a distinct metabolic profile in roots, whereas there was no difference in stem metabolites in response to different herbivore intensities. Significant combined feeding effects of the two herbivores on plant metabolic composition was only detected in leaves infested with high herbivore intensity. Generally,D. pallipesfeeding had a stronger effect on metabolite contents in different tissues compared toL. coenosafeeding. There was mostly a linear relationship between responses of leaf metabolites and herbivore intensity, whereas root metabolites generally showed non-linear responses to herbivore intensity. Additionally, there were significant interactions during simultaneous feeding of the two herbivores in leaves, which tended to be antagonistic. In general, our study suggested that plant responses to herbivory vary among tissues and are affected differently based on herbivore identity and intensity, which may vary in their interactions on plant metabolites at the whole-plant level.
