PGPR Secondary Metabolites for Enhanced Plant Protection against Phyto-Pathogens- A Review Paper | Original Article

ABSTRACT:

I INTRODUCTION

Plants are constantly exposed to a myriad of potential threats from pathogens such as bacteria, fungi, and viruses. Plant pathogens which cause diseases in plants result in reduction in plant yield; hence bio-control agents are helpful to enhance the plant growth promotion activities by controlling the plant diseases. Through bio-control microbes control the plant pathogen by secreting some specific type of secondary metabolites. To defend themselves, plants have evolved intricate defense mechanisms, including the production of secondary metabolites. These secondary metabolites play a crucial role in protecting plants from harmful pathogens. In recent years, there has been growing interest in harnessing the potential of Plant Growth-Promoting Rhizobacteria (PGPR) to stimulate the production of secondary metabolites in plants, thereby enhancing their resistance to pathogens. Plant rhizosphere is considered as the hot spot for the specific beneficial microbial colonization and proliferation due to the presence of the nutrient rich exudates (Renella et al., 2005). Due to the eco-friendly nature, use of theses microbes does not have any side effect on the environment and human health besides the PGPR have cost effective application in agriculture field.  This article explores the fascinating relationship between PGPR and secondary metabolites and their impact on plant protection.
