Genetics of Bacterial Diversity focuses on the rapidly developing field of ""non-K-12"" bacterial genetics that is largely outside the scope of other texts. The book begins with an introductory chapter that outlines the phylogenetic relationships of bacteria and the range of metabolic, behavioral, and developmental phenomena displayed by them. Two chapters then review the genetic processes found in bacteria generally, and discuss a range of genetic techniques used to analyze the various special systems described in the body of the book, respectively. Subsequent chapters deal with various special metabolic capabilities characteristic of certain groups of bacteria (light production, photosynthesis, nitrogen fixation, antibiotic production, degradation of aromatic compounds and mercury resistance); developmental processes of cell-cycle associated motility, sporulation, and specialized colonial behavior; four components of bacterial pathogenicity for animals; and pathogenic and symbiotic interactions of bacteria with higher plants. The final chapter explains some of the concepts and the progress being made in the application of population genetics to bacteria. This book may be of interest to microbiologists wishing to catch up on the genetic basis of some of the classical phenomena of bacteriology, and geneticists unfamiliar with some of the things that bacteria can accomplish.

The Sixth International Congress on Photosynthesis took place from 1 to 6 August 1983, on the Campus of the "Vrije Universiteit Brussel", in Brussels, Belgium. These Proceedings contain most of the scientific contributions offered during the Congress. The Brussels Congress was the largest thus far held in the series of International Congresses on Photosynthesis. It counted over 1100 active participants. The organizers tried to minimize the disadvantages of such a large size by making maximum use of the facili ties available on a university campus. Most contributions were offered in the form of posters which were displayed in a substantial number of classrooms. The discussion sessions, twice a day, four or five in parallel, took place in lecture rooms in the very vicinity of these classrooms. In this way it was attempted to generate the atmosphere of a small meeting. The unity of the subject Photosynthesis was preserved in the ten plenary lectures, organ1sed in such a way that a general overview of two diverse topics was given every day. In addition, there were the five times four parallel symposia dealing with some six teen general topics. Every editor of proceedings of a congress is faced with the problem of editing and arranging the contributions, a problem compounded by the wide diversity and the large number of the 753 manuscripts.

These Proceedings comprise the majority of the scientific cont ribut ions that were presented at the VIIth International Congress on Photosynthesis. The Congress was held August 10-15 1986 in Providence, Rhode Island, USA on the campus of Brown University, and was the first in the series to be held on the North American continent. Despite the greater average travel distances involved the Congress was attended by over 1000 active participants of whom 25% were registered st udent s . This was gratifying and indicated that photosynthesis will be well served by excellent young scientists in the future. As was the case for the VIth International Congress held in Brussels, articles for these Proceedings were delivered camera ready to expedite rapid publication. In editing the volumes it was interesting to reflect on the impact that the recent advances in st ruct ure and molecular biology had in this Congress. It is clear that cognizance of st ruct ure and molecular genetics will be even more necessary in the design of experiments and the direction of future research.

Advances in Microbial Ecology was established by the International Com mittee on Microbial Ecology (ICOME) as a vehicle for the publication of critical reviews selected to reflect current trends in the ever-expanding field of microbial ecology. Most of the chapters found in Advances in Microbial Ecology have been solicited by the Editorial Board. Individuals are encouraged, however, to submit outlines of unsolicited contributions to any member of the Editorial Board for consideration for inclusion in a subsequent volume of Advances. Contributions are expected to be in depth, even provocative, reviews of topical interest relating to the ecology of microorganisms. With the publication of Volume 8 of Advances we welcome to the panel of contributors Martin Alexander, the founding editor of this series, who discusses the range of natural constraints on nitrogen fixation in agri cultural ecosystems. Ecological aspects of cellulose degradation are dis cussed by L. G. Ljungdahl and K. -E. Eriksson, and of heavy metal responses in microorganisms by T. Duxbury. In his chapter, A. Lee con siders the gastrointestinal tract as an ecological system, and comments on the possibility of manipulating this system. The complex interactions among aerobic and anaerobic sulfur-oxidizing bacteria are discussed in terms of natural habitats and chemostat culture by J. G. Kuenen, L. Rob ertson, and H. van Gemerden. Finally, J. A. Robinson presents the advantages and limitations in the use of nonlinear regression analysis in determining microbial kinetic parameters in ecological situations. K. C.
