Fig. 6. Soil architecture associated with the abundance of microbial groups in rhizosphere
Rhizosphere soil porosity change ratio indicated by (a) the soil porosity at 0-1 mm relative to 1-2 mm root zone, and its correlation with the relative abundance ratio (rhizosphere : bulk soil) of microbes belonging to (b) ASV17781 annotated as unclassified Micrococcaceae (the core ASV), (c) Firmicutes, (d) Actinobacteria, (e) Acidobacteria, and (f) Chloroflexi of basal roots. Presented data included five soil types and three chickpea genotypes. * and ** indicated the significant correlation at P < 0.05 and P < 0.01, respectively.
