Pseudomonas fluorescens PpR24 colonization on Arabidopsis thaliana, Capsicum annuum and Beta vulgaris. (A) Bacterial populations recovered from A. thaliana leaves over a period of 21 days after spraying and infiltration with a cell suspension of 10⁷ CFU ml⁻¹. For foliar spray, bacteria were suspended in sterile PBS solution and a leaf disc was collected at all time points. Each leaf disc (N = 6) was homogenized in PBS solution and serial dilutions were plated on LB with nitrofurantoin to count bacterial populations. The data presented are the mean and standard error of six biological replicates. (B) Bacterial populations were recovered from plant leaf surfaces over period of 21 days after spraying with cell suspension of 10⁷ CFUmL^‐1. For the foliar spray, bacteria were suspended in sterile PBS solution and a leaf disc was collected at all time points. Each leaf disc (N = 6) was homogenized in PBS solution and serial dilutions were plated on LB with nitrofurantoin to count bacterial populations. The data presented are the mean and standard error of six biological replicates.
