Unraveling of Plant-Soil-Microbe Interactions for Phytoremediation of Heavy Metal Contaminated Soils Considering Future Climate Change Impacts

by Ying Ma

Anthropogenic activities and pedogenesis of soils derived from ultramafic rocks have caused heavy metal contamination worldwide. During the last two decades, phytoremediation has emerged as a potential eco-friendly tool to clean up heavy metal contaminated environments. However, various climatic stresses can affect physiobiochemical activities of remediating plants as well as heavy metal bioavailability in soils, therefore hampering phytoremediation efficiency. This situation could be ameliorated by exploring the plant-microbe partnership, which can improve plant growth and facilitate plant metal uptake. In this book, topics of contemporary importance are covered including plant-soil-microbe interactions at the - molecular level (molecular signals and quorum sensing) - cellular and organismal level (establishment of associative symbiosis of plant and microbes) - biogeochemical level (heavy metal detoxification, mobilization, immobilization, transformation, transport and distribution) - ecosystem level (mechanisms involved in plant-microbe-metal interactions)and at the - technological application level (case study of using plant growth to promote rhizobacterium for phytoremediation) Additionally, climate change effects on plant-metal-microbe interactions and phytoremediation are also included. This book brings a state-of-the-art review on microbe-assisted phytoremediation resulting from plant-microbe-metal interactions, providing high quality academic knowledge and understanding of this remediation technology.
