Summary: This book provides a straightforward and easy-to-understand overview of beneficial plant-bacterial interactions. It features a wealth of unique illustrations to clarify the text, and each chapter includes study questions that highlight the important points, as well as references to key experiments. Since the publication of the first edition of Beneficial Plant-Bacterial Interactions, in 2015, there has been an abundance of new discoveries in this area, and in recent years, scientists around the globe have begun to develop a relatively detailed understanding of many of the mechanisms used by bacteria that facilitate plant growth and development. This knowledge is gradually becoming an integral component of modern agricultural practice, with more and more plant growth-promoting bacterial strains being commercialized and used successfully in countries throughout the world. In addition, as the worlds population continues to grow, the pressure for increased food production will intensify, while at the same time, environmental concerns, mean that environmentally friendly methods of food production will need to replace many traditional agricultural practices such as the use of potentially dangerous chemicals. The book, intended for students, explores the fundamentals of this new paradigm in agriculture, horticulture, and environmental cleanup.
