Plant Disease Transmission

Microorganisms play a vital role in the health of animals, plants, and soil ecosystems. They decompose organic matter, providing essential nutrients for plant growth, and are crucial to the productivity of agricultural systems. Microorganisms form the foundation of the global food web, supporting plant growth, which is the primary food source for humans and animals. While most microorganisms benefit plants by protecting against diseases and supplying nutrients, some have evolved strategies to acquire nutrients in ways that harm plants. These plant pathogens cause diseases that can significantly impact crop yield and quality, with consequences for food security and the economy. Plant pathogens spread through wind, rain, insects, animals, and contaminated equipment, with some using flagella to move actively. Plant diseases typically show visible symptoms, especially on above-ground parts. These diseases have wide-ranging effects on Sustainable Development Goals.
