Current Status and Future Perspective on Enzyme Involving in Biocontrol of Plant Pathogen

Abstract

Plant diseases must be controlled to maintain the quality and quantity of food produced by farmers worldwide. Various strategies exist to prevent, reduce, or manage plant diseases. Agronomic and horticultural methods depend on chemical fertilisers and insecticides. These agricultural inputs have contributed significantly to recent gains in crop output and quality. Microbial enzymes help bacteria multiply in a specific habitat by acting as biocatalysts for biochemical processes. It has long been recognised that rhizosphere microorganisms may boost plant development and suppress phytopathogens. Rhizosphere microorganisms may help plants fight phytopathogens in numerous ways. Excreting lytic enzymes is one of the acknowledged biocontrol methods for preventing phytopathogens from surviving in the rhizosphere. To combat phytopathogens, rhizosphere microbes create chitinases, cellulases, proteases, and glucanases. Biological management may soon replace fungicides, say UBC researchers. New molecular approaches are now available to study antagonist-pathogen interactions, rhizosphere antagonist ecology, and biocontrol agent efficacy. Because agro-ecosystems are dynamic structures with numerous factors affecting disease and crop productivity, alternative IPM strategies to manage crop diseases are useful in various environments. Diverse crop systems need IPM management options other than biological control to successfully prevent disease development and yield loss.
