endophytes not only affect the growth and resistance of their host plants but also confer nutrient benefits to parasitized hosts. In this study, we used to parasitize , both with and without endophytic fungi, and to establish a parasitic system. In this study, endophytic fungal infection was found to increase the dry weight of the leaf, stem, and leaf sheath, as well as the plant height, root length, tiller number, aboveground biomass, and underground biomass of under root hemiparasitic stress. Meanwhile, the C allocation of the leaf sheaths and roots of increased as the density of increased, while the C allocation of the leaf sheaths and roots of E+ was lower than that of E- . The C allocation of the stem, leaf sheath, and root of E+ was higher than that of its E- counterpart. Furthermore, the content of photosynthetic C and the C partition rate of the stems, leaves, roots, and entire plant of and transferred from increased as the density of increased. These results will generate new insights into the potential role of symbiotic microorganisms in regulating the interaction between root hemiparasites and their hosts.
内生菌不仅影响宿主植物的生长和抗性,还为被寄生的宿主提供养分益处。在本研究中,我们利用[具体内容1]对[具体内容2]进行寄生,分别设置有内生真菌和无内生真菌的情况,从而建立了一个寄生系统。在本研究中,发现在根半寄生胁迫下,内生真菌感染增加了[具体植物名称]叶片、茎和叶鞘的干重,以及植株高度、根长、分蘖数、地上生物量和地下生物量。同时,随着[具体内容3]密度的增加,[具体植物名称]叶鞘和根的碳分配增加,而E+[具体植物名称]叶鞘和根的碳分配低于E-[具体植物名称]。E+[具体植物名称]茎、叶鞘和根的碳分配高于其E-对应物。此外,随着[具体内容3]密度的增加,从[具体植物名称]转移到[具体植物名称]的光合碳含量以及茎、叶、根和整株植物的碳分配率增加。这些结果将为共生微生物在调节根半寄生植物与其宿主之间相互作用中的潜在作用提供新的见解。
