2016), and most of these effects are induced via root exudates (Bakker et al. Studies have shown that host plants can profoundly impact the diversity, richness, relationships and activity of the rhizospheric microbiome (Tkacz et al. Therefore, the effects of plants on the rhizospheric microbiome have received much attention. The rhizospheric microbiome inhabits the compartment between plant roots and soils thus, the effects of plants on the rhizospheric microbiome should be stronger than those on the soil microbiome (Edwards et al. Identifying the complex factors that control rhizospheric microbial communities in natural ecosystems is a key starting point for harnessing the rhizospheric microbiome in agricultural and natural ecosystems, which is important for sustainable crop production and maintaining ecosystem health. The rhizospheric microbiome is governed by multiple factors, including plant development, plant genotype, soil characteristics, and regional environmental conditions and by the interactions among these factors (Philippot et al. 2009), plays a critical role in plant health, nutrient uptake and biogeochemical cycling (Berendsen, Pieterse and Bakker 2012 Philippot et al. The rhizospheric microbiome, a subset of the total soil microbial community (Buée et al. Rhizospheric microbiome, influential factors, plant, soil, site INTRODUCTION 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.
Furthermore, rhizospheric fungi were more strongly influenced by plants than rhizospheric bacteria. 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. 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. hexandra ( Leersia hexandra Swartz)), two soils (high nutrient and low nutrient) and two sites (Guangdong and Hainan provinces in China).
A series of comparisons of rhizospheric microbiomes were conducted using two plants (wild rice ( Oryza rufipogon Griff.) and L. 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. The rhizospheric microbiome appears to be one of the key determinants of plant health and productivity.
