This volume provides a comprehensive coverage of the principal extreme soil ecosystems of natural and anthropogenic origin. Extreme soils oppose chemical or physical limits to colonization by most soil organisms and present the microbiologist with exciting opportunities. Described here are a range of fascinating environments from permafrost to Martian soils. The book includes chapters on basic research in addition to applications in biotechnology and bioremediation.

Molecular Mechanisms of Plant and Microbe Coexistence presents studies on the complex and manifold interactions of plants and microbes at the population, genomics and proteomics level. The role of soil microbial diversity in enhancing plant health and plant microbe beneficial symbioses is discussed. Microbial communities are shown in the light of evolution. Main topics include genome coexistence and the functional genomics and proteomics of plant-associated microbes, which could form the basis for new environmentally benign strategies to combat infectious plant diseases and regulate plant growth. Further chapters focus on the role of signaling during the different stages of plant microbe coexistence, in symbiotic or pathogenic relationships, in quorum sensing and plant viral infections. Methods for studying the interactions in the root zone complement the book, which will certainly be of relevance in the practical application to agriculture, food security and for maintaining the balance of our ecosystems.

Since ancient times microorganisms have proven themselves a protective warrior to fight against many problems in the favor of humankind and therefore their potential applications are expected to increase significantly in various area. Microorganisms are known to detoxify or magnify the toxicity of allelochemicals after their entry into soil, and thus influence allelopathic activities. There could be more than one mechanisms of action of such microbes affecting the fate of allelochemicals in soil. Therefore future allelopathy research should be designed to understand the interaction of allelochemicals with soil microbes. However, their significance in influencing allelopathic activity is largely not investigated in bioassays for allelopathy. In this book, therefore, an attempt has been made to focus mainly on this aspect of allelopathy where phytoxicity of invasive weed can be minimized by using beneficial rhizobacteria without having any harmful effects on non-target plants, soil and ecosystem. An approach has been made to cover all possible aspects of soil microbial ecology in allelopathic interactions which can provide a baseline for futuristic studies.
