A free living Plant growth promoting rhizobacteria (PGPR) Pseudomonas fluorescens are able to colonize around plant root and incorporate free atmospheric molecule into plant absorbable nutrient form along with improved plant growth and crop yield. Their unique metabolic properties directly inhibiting the pathogens either by producing antibiotics and extracellular lytic enzymes to lyse the pathogens. In vivo expression technology (IVET) analysis of rhizosphere‐induced genes in the plant growth‐promoting rhizobacterium (PGPR) Pseudomonas fluorescens SBW25 identified a homologue of the type III secretion system (TTSS) gene hrcC .The hrcC homologue resides within a 20‐kb gene cluster that resembles the type III (Hrp) gene cluster of Pseudomonas syringae . Four biofertilizers viz., Rhizobium (CRR6/CPR9), Azotobacter (NB-1), Azospirillum (Az-204), Phosphobacteria (Bacillus megaterium, TNAU-1) and two biocontrol agents viz., Pseudomonas fluorescens (PF-1) and Bacillus subtilis (Bbv-57) were obtained as commercial talc … Diverse mechanisms are involved in the suppression of plant pathogens, which is often indirectly connected with plant growth.

In this study, we characterized P. fluorescens BRZ63, a new endophyte of oilseed rape (Brassica napus L.), and demonstrated its phenotypic functionality related to the inhibition of the growth of fungal pathogens, biocontrol, and plant growth promotion. It is known that compounds such as siderophores are synthesised mainly during the exponential growth phase, which is the stage in which the population requires more nutrients for cell division (O’Sullivan and O’Gara, 1992). The efficacy of bacterial antagonists in controlling fungal diseases was often better as alone, and sometimes in combination with fungicides. ability for plant growth promotion and effective disease management properties, root colonization by Pseudomonas fluorescens, biotic and abiotic factors affecting colonization and mechanisms of pathogen suppression. A previous work has shown that this pseudomonad isolate was able to produce diverse diffusible and volatile compounds involved in plant protection and growth promotion.
