Book Description
As much as 80% of the seed protein found in soybean seeds can be attributed to the nitrogen-fixing activity of the microsymbiont, Bradyrhizobium japonicum, that resides in root nodules of soybean. The effectiveness of this combination is limited, however, and the duration of nitrogen fixation lasts only about 3 weeks. B. japonicum infects soybean roots by inducing formation of infection threads and cortical cell division centers that will form nodule primordia. Once this organism reaches these centers, it infects the cells by the process of endocytosis. The microsymbiont resides within them in a specialized structure, known as a symbiosome. In this study I examined ultrastructurally and biochemically the development of this symbiotic relationship by infecting the soybean cultivar Williams 82 with four closely-related strains of B. japonicum. I report here that symbiotic effectiveness (persistence of nitrogen fixation) is dependent upon the ability of these microorganisms both to infect and persist within the root nodule. I also present evidence that ultrastructurally observable host defense responses are correlated with limited infection potential and the early decline of nitrogen fixation.

Molecular Biology Of Symbiotic Nitrogen Fixation
Author: Peter M. Gresshoff
Publisher: CRC Press
ISBN: 1351083198
Category : Medical
Languages : en
Pages : 278
Book Description
The core of the text is aimed at the research worker in the field of nitrogen fixation, but, despite its specialisation, does not lose the emphasis on teaching, both as a direct reference book and as a backbone for a graduate course on the subject.The closing part of the book includes a subject index and a glossary of terms. The latter was included not for the expert, for whom many of the definitions will be too general, but for the newcomer; the author hopes that the quick survey of key terms will help in the reading of this book.
