西伯利亚草可被两种真菌内生真菌侵染，即甘肃表壳菌(Eg)和西伯利亚表菌(ES)。本研究采用GC-MS联用技术对Eg、Es及其侵染植株的代谢产物进行了研究。结果表明，乙酸乙酯和乙酸乙酯的代谢谱基本相似，仅检测到6种不同的代谢物。内生真菌侵染对西伯利亚木霉代谢产物的直接影响是内生真菌侵染植株可以产生甘露醇，而未感染的植株中不存在甘露醇。Eichloë侵染间接导致西伯利亚冰草中与生长相关的可溶性糖增加，以及与抵御病原体和食草动物有关的代谢产物如α-生育酚、α-亚麻酸和芳香氨基酸的增加。表观感染可调节寄主牧草的半乳糖代谢、淀粉和蔗糖代谢、酪氨酸代谢和苯丙氨酸代谢。此外，内生菌与寄主之间的代谢产物含量也呈显著正相关。
Achnatherum sibiricum can be infected by two species of fungal endophytes, Epichloë gansuensis (Eg) and Epichloë sibirica (Es). In this study, the metabolites of Eg, Es, and their infected plants were studied by GC–MS analysis. The results showed that the metabolic profiles of Eg and Es were similar in general, and only six differential metabolites were detected. The direct effect of endophyte infection on the metabolites in A. sibiricum was that endophyte-infected plants could produce mannitol, which was not present in uninfected plants. Epichloë infection indirectly caused an increase in the soluble sugars in A. sibiricum related to growth and metabolites related to the defense against pathogens and herbivores, such as α-tocopherol, α-linolenic acid and aromatic amino acids. Epichloë infection could regulate galactose metabolism, starch and sucrose metabolism, tyrosine metabolism and phenylalanine metabolism of host grass. In addition, there was a significant positive correlation in the metabolite contents between the endophyte and the host.
