Study on the Role of Arbuscular Mycorrhizal Fungi (AMF) in Plant Growth | Chapter 1 | New Visions in Biological Science Vol. 7

 Symbionts known as "Arbuscular Mycorrhizal Fungi" (AMF) can be found in the world's most remote biomes and are essential for plant growth and maturation. The well-known AMF class that colonises the roots of over 80-90 percent of land plant families, but which cannot be cultured away from the host plant at this time. AMF are primarily responsible for nutrition transfer from soil to plant, but they also perform other functions such as soil aggregation, plant protection from drought and metal stress, as well as soil pathogens and rising plant diversity. The enlargement of the fungal mycelium within a host root and out into the soil accomplishes this. Because AMF are crucial in closing nutrient cycles and have a shown multi-functional responsibility in soil-plant associations, there is an urgent need to investigate the below-ground microbiology of soils in agro and natural systems. More research on the functional variety of these microorganisms, as well as their interactions with all plants, is also required. With important advancements in contemporary research in the field of AMF investigation, the processes involved in host-plant interactions with other soil organisms are being studied in greater depth. The days of applying AMF in both limited and open-field circumstances are long gone. This chapter also provides an overview of current information about the importance, incidence, and advantages of AMF in various plant ecosystems. The effects of nitrogen transfer between AMF and host plants on plant growth and their implications for sustainable farming are examined. The impact of co-inoculation and other beneficial AMF bacteria on plant development and root colonisation is discussed. AMF's role in water intake and interaction with legume plants, including nodulation and N2 fixation, is briefly discussed. The importance of AMF in plant-based solutions for protecting soils polluted with highly hazardous Heavy Metals (HMs) is also highlighted.
