Strain-specific quantification of root colonization by plant growth promoting rhizobacteria Bacillus firmus I-1582 and Bacillus amyloliquefaciens QST713 in non-sterile soil and field conditions
Fig 6
Root colonization of field grown corn seedlings by B. firmus I-1582 and B. amyloliquefaciens QST713.
Corn seeds were treated with (A) 106 spores of B. firmus I-1582 (T1 and T2) and (B) 106 spores of B. amyloliquefaciens QST713 (T1 and T2). T3 = uninoculated. qPCR quantification was performed with B. firmus I-1582 or B. amyloliquefaciens QST713 specific primers and probe using a standard curve. Error bars show Standard Error (n = 5 seedlings). Same letters on top of bars represent non-significant differences (P = 0.387) for each variety according to two-way ANOVA.
