Unit 2: Microbe-Plant interaction: Symbiotic interactions
Earth is richly populated with plants, and many different types of microorganisms grow in close association with them. While microbial activities detrimental to plant growth may be the most obvious, microorganisms are also beneficial to plants. Microorganisms may provide some nutritional benefit to a plant host, and this would result in increased plant growth. Over time different interactions between microorganisms (bacteria, fungi, or algae) and plants have been identified, and several of these activities. The two best characterized symbiotic systems are the fungus–root system and the bacterium–root nodule system.
