Mycorrhizal Fungi
Aggarwal, Ashok
Información del libro
Arbuscular Mycorrhizal fungi are obligate root symbionts that are present in most terrestrial ecosystem and establish a mutualistic symbiosis with several plant species around the world. The use of biofertilizers as a source of plant nutrients for more sustainable agriculture practices involves a large number of microorganisms including AM fungi which have potential to enhance productivity in combination with a reduction in application of fertilizer. Mycorrhizas are an essential below-ground component in the establishment and sustainability of plant communities but thorough knowledge is required to have maximum benefits from these microorganisms. The book provides the various functional and potential application of AM fungi including topics such as biodiversity and dynamics of root colonization, phosphorus acquisition by AM Fungi, soil carbon sequestration, alleviation of salt stress, water stress, heavy metal toxicity, in mining site rehabilitation and biocontrol agent. This book will be a rich source of inspiration for research and exploitation of the potential of mycorrhizal fungi.
