How can bacteria benefit plants?

Abstract

Bacteria are microscopic, single-celled organisms found almost everywhere on earth in vast numbers. They are extremely diverse and play a major role in nature, contributing to plant growth and health. Agriculture provides a major share of the national income in many developing countries. However, diseases cause significant yield and economic losses in many important agricultural crops. Farmers have adopted a strategy to increase crop yields by applying large quantities of chemical fertilizers and pesticides. The use of chemical-based fertilizers offers some protection against plant pathogens and provides immediate relief, but cannot provide a long-term sustainable solution. The excessive use of chemical-based fertilizers also causes severe environmental problems. Many countries have banned the use of certain hazardous chemicals, including some pesticides that are used to control plant diseases. For example, methyl bromide, used in the control of pests, has been banned internationally because of its adverse effects on human health and ...
