Nodules produced on legume roots by root-nodule bacteria provide the major nitrogenous input into natural and agricultural systems worldwide. This book provides an in-depth and up-to-the minute analysis of what is known about this symbiosis, its origins, the process of nodule formation and development, and the biochemistry and genetics of nodular nitrogen fixation. It also reviews the physiology of the root-nodule bacteria themselves, their ecology in both natural and agricultural systems, and how we go about introducing new legumes and the bactria they require.

Nodules produced on legume roots by root-nodule bacteria provide the major nitrogenous input into natural and agricultural systems worldwide. This book provides an in-depth and up-to-the minute analysis of what is known about this symbiosis, its origins, the process of nodule formation and development, and the biochemistry and genetics of nodular nitrogen fixation. It also reviews the physiology of the root-nodule bacteria themselves, their ecology in both natural and agricultural systems, and how we go about introducing new legumes and the bactria they require. How all the knowledge gained about this system can be applied in the future for better legume-rhizobia functioning in difficult environments is its logical culmination.

Rezensionen
From the reviews: "This is the final volume in a comprehensive seven volume series on all aspects of nitrogen fixation, one of the key biological processes on the planet and still a major provider of nitrogen in agro-ecosystems. ... A wide range of topics is ... presented in an easy to read style, with good clear diagrams and figures. ... This is a well-written comprehensive text, with extensive bibliographies, that will be useful to students and academics at all levels, and is to be recommended strongly." (Ron Wheatley, Experimental Agriculture, Vol. 45, 2009)
