Abstract
Pseudomonas fluorescens belongs to Plant Growth Promoting Rhizobacteria (PGPR), is a gram-negative, rod-shaped bacterium. It is the most favoured bioinoculant due to its significant properties in both plant growth and phytopathogen control during its synergistic association with the host plant. These properties include Phyto-hormone production, siderophore production, phosphate solubilization, phenazines production and antibiotics production. The association of P. fluorescens with crop plants procures several secretory and electron-based feedback mechanisms in order to regulate the plant growth and phytopathogen control activities through the secretion of several phytohormones (auxins, gibberellins, indole-3-acetic acid), secondary metabolites (flavonoids) and enzymes (aminocyclopropane-1-carboxylate, phenylalanine ammonia-lyase). Ecologically significant applications of P. fluorescens in biocontrol and bioaugmentation are crucial for maintaining food security.
