Phylloplane bacteria and their role in plant disease management

Abstract

The phylloplane, a microbial-rich habitat on the aerial surfaces of plants, plays a crucial role in plant health and disease management. This review explores the diverse microbial communities of the phylloplane, particularly bacteria, and their significant contributions to plant growth, pathogen resistance, and ecological balance. Phylloplane microbes employ competitive strategies such as the production of antimicrobial compounds, induction of systemic resistance, and enhancement of photosynthetic efficiency. Moreover, they facilitate nutrient cycling, nitrogen fixation, and phytohormone production. Recent studies highlight their potential as biocontrol agents in sustainable agriculture, emphasizing their effectiveness in suppressing pathogens and promoting plant health. Understanding the dynamics of phylloplane microbes offers promising avenues for improving crop productivity and reducing reliance on chemical inputs.
