Speargrasses’ rhizosheath-root system microbial community distribution and composition. a, b Abundance of bacterial and fungal components in rhizosheath-root system (root tissues, rhizosheath, rhizosphere and bulk sand) of speargrasses measured by quantitative PCR of 16S rRNA and ITS gene copies per gram of sample, respectively. Lowercase letters indicated the significative difference (post hoc Dunn multiple comparison test) among speargrasses species for each compartment, while the significant difference among compartments was indicated by capital letters (post hoc Dunn multiple comparison test for bacteria and Mann-Whitney t test for fungi). n.d.: not detected. (c, d) Rank abundance distribution of bacterial (c) and fungal (d) SVs associated with speargrasses’ rhizosheath-root system (root, rhizosheath and rhizosphere) and bulk sand. (e, f) Power-law relationship between prevalence in speargrass rhizosheath-root system (measured by degree) and abundance (measured by the number of reads) for host-associated bacterial (e) and fungal (f) SVs. * not detected in bulk sand; # not detected in the internal root tissues
