Microbiome Nano-Cross-Talk: Sustainable Agriculture and Beyond presents a comprehensive overview of the functional aspects of multiphasic microbial and nanotechnological interactions within and between plants and their ecosystem. Recognizing that beneficial microbes are involved in plant growth promotion, this book highlights their mechanism and regulation to enhance plant's yield and development even under stressed conditions. The merging of nanotechnology with microbiology is an essential aspect of this book. Various nanomaterials, their synthesis approaches as well as applications in agriculture have been studied extensively in past years. With a focus on focus the morphological, anatomical, biochemical, molecular and gene expression levels of plant growth promotion, the book is the first of its kind to enable scientists to unravel the different pathways and signaling cascades involved in response to this interaction and to understanding how nanomaterials regulate the plant-microbe associations. It critically examines the role of beneficial microbes in conjunction with nanoparticles in plants and the mechanisms adopted by the plants at the biochemical and molecular levels to enhance plant growth and mitigate various stresses.
