Taylor & Francis Inc Mycorrhizas: A Molecular Analysis
The book begins with a chapter on Molecular Evolution and Phylogeny of mycorrhizas. Lucid discussions on cellular physiology, molecular genetics, and molecular regulation of nutrient exchange phenomenon in mycorrhizas form the core of this book. A comparative analysis of the molecular aspects of symbiosis and pathogenesis has been presented in detail. It also includes certain agriculturally useful aspects of disease control via mycorrhizas. Discussions on recent developments in molecular ecology of mycorrhizas, including most recently enunciated concepts such as ?nurse functions?, ?mycoheterotrophy? are provided in the book. Transformation, transgenics and genetic engineering of mycorrhizas is a unique and futuristic chapter. Applications of genetic engineering of mycorrhizas, as well as recently developed techniques of genetic transformation production of viable transgenic mycorrhizal fungi have been delineated. It will be useful to researchers/students involved in Microbiology, Molecular Biology, Plant Bio

Apple Academic Press Inc. Agricultural Prairies: Natural Resources and Crop Productivity
This book is a comprehensive volume that brings together vast knowledge about agricultural prairies in one place, providing concise information and providing concise descriptions of natural resources and their influence on crop productivity. It provides detailed descriptions about natural settings as well as lucid discussions on soil fertility and crop production trends for various agricultural prairies distributed all across the earth. Chapters one through seven provide detailed descriptions on geologic aspects; physiography and agroclimate; natural vegetation and cropping history; human population, migration and development of settlements; natural resources such as soils, water, and crops; and environmental concerns. In particular, the first chapters cover the prairies of North and South America, namely, the Great Plains of North America, the Cerrado of South America, and the Pampas of South America. Chapter 4 deals with the steppes of Southern and Central Europe, Chapter 5 describes the savannahs of West Africa, Chapter 6 is concerned with Indo-Gangetic and Deccan plainsm, and Chapter 7 deals with prairies of Northeast China. The last chapter provides a comparative view of all agricultural prairies. Specifically, it compares the contrasting natural features, soil fertility, irrigation, and crop productivity. Agricultural prairies exist at levels of intensification. A few show subsistence or low input trends. Discussions pertaining to extent of intensification are included. Further, it includes interesting discussions on how the situation has grown into interdependence of man and prairies. It highlights the way prairies (crops) have influenced, naturally coaxed, and driven human activities to their own advantage.

Taylor & Francis Inc Agrosphere: Nutrient Dynamics, Ecology and Productivity
The book deals with agroecological aspects of nutrients essential to crop production. A new concept termed 'AGROSPHERE' has been introduced in the book. A brief description about agrosphere, its expanse, contrasting features and interactions with other ecospheres, global nutrient dynamics and food production trends within various agro ecosystems forms the introductory chapter. The book encompasses discussions on the major agroecosystems/ cropping belts that contribute to global food grain harvests, fruits and other beneficial commodities.
