Increasing population and the expected decrease in crop production due to climate changes and land damage in near future may be rescued by changing from animal meat to plant protein, especially soybean protein. Recently, meat substitutes produced from soybean have become popular This book discusses recent advances in research and applications of soybean. Soybean seeds contain an extraordinarily high concentration of protein and oil, and the demand for soybean is increasing due to their nutritional value for both humans and livestock. Also, soybean has been used as biofuel in the replacement of petroleum oil. This book gives a comprehensive overview of soybean in five sections: "Role of Soybean for Food Security", "Physiology and Biochemistry of Soybean Plants", "Cultivation and Productivity of Soybean", "Breeding and Biotechnology of Soybean", and "Food and Biodiesel Industry".

Biological nitrogen fixation has essential role in N cycle in global ecosystem. Several types of nitrogen fixing bacteria are recognized: the free-living bacteria in soil or water; symbiotic bacteria making root nodules in legumes or non-legumes; associative nitrogen fixing bacteria that resides outside the plant roots and provides fixed nitrogen to the plants; endophytic nitrogen fixing bacteria living in the roots, stems and leaves of plants. In this book there are 11 chapters related to biological nitrogen fixation, regulation of legume-rhizobium symbiosis, and agriculture and ecology of biological nitrogen fixation, including new models for autoregulation of nodulation in legumes, endophytic nitrogen fixation in sugarcane or forest trees, etc. Hopefully, this book will contribute to biological, ecological, and agricultural sciences.
