Arbuscular mycorrhizal fungi (AMF), which form symbioses with most land plants, could benefit their hosts and potentially play important roles in revegetation of degraded lands. However, application desert grasslands still faces challenges uncertainties due to the unclear specificity AMF-plant interactions. Here, Caragana korshinskii microphylla were inoculated either conspecific (home) or heterospecific (away) AM fungal communities from rhizosphere three common plant species (C. korshinskii, C. Hedysarum laeve) Kubuqi Desert, China. AMF inocula home away effects on growth nutrition status two examined. Results showed that H. laeve significantly different, characterized by high abundance Diversispora, Archaeospora, Glomus, respectively. The shoot biomass, photosynthetic rate, foliar N P contents only increased under inoculation 167.10%, 73.55%, 9.24%, 23.87%, no significant found, regardless AMF. Positive correlations between biomass genus Diversispora found. Our study strong advantage using native community enhance presented a efficient way use restoration practices.

1. Though not often examined together, both plant-soil feedbacks (PSFs) and functional traits have important influences on plant community dynamics could interact. For example, seedling impact survivorship responses to soils cultured by conspecific versus heterospecific adults. Furthermore, levels of vary with soil culturing source. In addition, these relationships might shift light availability, which can affect trait values, microbe abundance, whether mycorrhizal colonization is mutualistic or parasitic seedlings. 2. To determine the extent mediate PSFs via survival, we conducted a field experiment. We planted seedlings four temperate tree species across gradient availability into cores collected beneath (sterilized live) monitored survival twice per week over one growing season, randomly selected subsets measure phenolics, lignin, NSC at three weeks. 3. evidence for was limited, Acer saccharum exhibited positive (i.e., higher in than soils). microbes had negative effect A. Prunus serotina reduced live sterilized soil. general, found values (measured amounts given trait) availability. Additionally, increased were high light. Quercus alba decreased AMF colonization. 4. demonstrate that as young weeks response source Moreover, associated two species, despite drought heavy rainfall during season may obscured survivorship-trait relationships. These results suggest an role mediating effects local thus PSFs.

Abstract Pairwise interactions between species can be modified by other community members, leading to emergent dynamics contingent on composition. Despite the prevalence of such higher-order interactions, little is known about how they are linked timing and order species’ arrival. We generate population from a mechanistic plant-soil feedback model, then apply general theoretical framework show that modification pairwise interaction third plant depends its germination phenology. These time-dependent modifications emerge concurrent changes in microbe populations strengthened higher overlap plants’ associated microbiomes. The this specificity microbiomes further determines coexistence. Our widely applicable mechanisms systems which similar emerge, highlighting need integrate temporal shifts predict natural communities.
