Abstract

Pseudomonas fluorescens is an important kind of plant growth-promoting rhizobacteria(PGPR).It can produce many secondary metabolites,such as pyoluteorin,2,4-diacetylphloroglucinol,pyrrolnitrin and phenazine-1-carboxyl acid.These antibiotics play a major role in suppression of many pathogens.The synthesis mechanisms of the secondary metabolites in Pseudomonas fluorescens,especially the structures and functions of the related genes were summarized.At the same time,the applications of Pseudomonas fluorescens in biological control are presented.
