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.
