This volume illustrates the complex root system, including the various essential roles of roots as well as their interaction with diverse microorganisms localized in or near the root system.

Following initial chapters describing the anatomy and architecture as well as the growth and development of root systems, subsequent chapters focus on the various types of root symbiosis with bacteria and fungi in the rhizosphere. A third section covers the physiological strategies of roots, such as nitrate assimilation, aquaporins, the role of roots in plant defense responses and in response to...

"Advanced Techniques in Soil Microbiology" presents a wide range of biotechnological methods for application in soil microbiology analysis. These include all essential methods involving molecular biology, immunology, microbiology, and structural biology, such as transcriptome analysis, RNAi technology, molecular matchmaking, RAPD, T-RFLP and FT/MS.

The techniques and procedures have been selected with the aim of offering practical guides for immediate use in the laboratory. The systems investigated range from individual molecules and cells to entire eukaryotic organisms, with a...

In response to low iron availability in the environment most microorganisms synthesize iron chelators, called siderophores. Bacteria and fungi produce a broad range of structurally diverse siderophores, all of which show a very high affinity for ferric ions.

This book presents an up-to-date overview of the chemistry, biology and biotechnology of these iron chelators. Coverage ranges from an introductory chapter to siderotyping to applications in human and plant health.

Metal contamination is an increasing ecological and eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils are key features for soil bioremediation.

Following an introduction to the physical, chemical and biological components of contaminated soils, various chapters address the interactions of soil, microorganisms, plants and the water phase necessary to transfer metals into biological systems. These include topics such as potential hazards at mining sites; rare earth elements in biotic and abiotic acidic systems;...

Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils.

The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on...

This book provides a timely review of concepts in plant disease management involving microbial soil suppressiveness and organic amendments.

Topics discussed include the impact of suppressive soils on plant pathogens and agricultural productivity, the enhancement of soil suppressiveness through the application of compost and the development of disease suppressive soils through agronomic management. Further chapters describe diseases caused by phytopathogens, such as Pythium, Fusarium and Rhizoctonia, interaction of rhizobia with soil suppressiveness factors, biocontrol of plant...
