Abstract
The tendency of closely related plant species to share natural enemies has been suggested to limit their co-occurrence and performance, but we lack a deep understanding on how mutualistic interactions such as the mycorrhizal symbiosis affect plant-plant interactions depending on the phylogenetic relatedness of the interacting plants. We hypothesise that the effect of the mycorrhizal symbiosis on plant-plant facilitative interactions depends on the phylogenetic distance between the nurse and facilitated plants. A recently published meta-analysis compiled the strength of plant facilitative interactions in the presence or absence (or reduced abundance) of mycorrhizal fungi. We use phylogenetically informed Bayesian linear models to test whether the effect size is influenced by the phylogenetic distance between the plant species involved in each plant facilitative interaction. Conspecific facilitative interactions are more strongly enhanced by mycorrhizal fungi than interactions between closely related species. In heterospecific interactions, the effect of the mycorrhizal symbiosis on plant facilitation increases with the phylogenetic distance between the nurse and facilitated plant species. Our result showing that the effect of mycorrhizal symbiosis on the facilitation interactions between plants depends on their phylogenetic relatedness provides new mechanisms to understand how facilitation is assembling ecological communities.

Abstract
ABSTRACT
The rhizospheric microbiome appears to be one of the key determinants of plant health and productivity. In this study, to understand the assembly process of the rhizospheric microbiome, the effects of different sites, soils and plants on the rhizospheric microbiome were compared and examined using high-throughput sequencing. A series of comparisons of rhizospheric microbiomes were conducted using two plants (wild rice (Oryza rufipogon Griff.) and L. hexandra (Leersia hexandra Swartz)), two soils (high nutrient and low nutrient) and two sites (Guangdong and Hainan provinces in China). The results of the redundancy analysis, between-class analysis and coinertia analysis indicated that the factors shaping the rhizospheric microbiome (in decreasing order of strength), were the site, soil and plant. The effects of plants on the rhizospheric microbiome were slight and unobvious, with relatively low-explained variations and few core groups and indicator groups; however, the effects were significant across different sites and soils, especially for specific microbial groups that are closely associated with plants, such as pathogens, symbionts, and saprotrophs. Furthermore, rhizospheric fungi were more strongly influenced by plants than rhizospheric bacteria. Our results provide insights into the relationships among multiple factors that shape the rhizospheric microbiome in natural ecosystems and highlight the effects of plants across regional environmental shifts.
