Effect of Endophyte on the Growth and Carbon Allocation of Its Host Plant under Hemiparasitic Root Stress.

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.
