The potential biocontrol effect (a). Phenotype analysis of cotton seedlings. After 24 h inoculated with sterile distilled water and candidated bacterial solution, the cotton seedlings were inoculated with V991 conidial suspension and treated at 14 dpi. (b). The disease index analysis. (c). Fungal biomass detection. The cotton small subunit ribosomal RNA gene (SSU) was used as an endogenous control, while Verticillium ITS1 and ITS2 regions of the ribosomal RNA genes (Z29511) was selected to quantify the colonization of V. dahliae. Error bars represent the standard deviations from three independent experiments and different letters indicate significant differences at p < 0.05 as determined using a Duncan’s test.
