The evolutionary relationship between Frankia and actinorhizal plants was evaluated by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia strains. Although the branching order of Frankia 16S rDNA and plant rbcL trees were different, subgroupings of Frankia and of plants correlated well in terms of symbiotic partnership. Tree matching, estimated divergence times, and molecular clock hypothesis tests indicated that Frankia clades diverged more recently than plant clades and that actinorhizal symbioses originated more than three times after the plant clades diverged. A phylogenetic tree of Ceanothus species, which are symbiotic partners of Frankia, was reconstructed using ndhF gene sequences. The analysis identified two main clades corresponding to two subgenera: Ceanothus and Cerastes. The analysis also suggested that three monophyletic clades within the subgenus ceanothus can be delimited on the basis of vegetative characters. Based on rbcL sequences, the two subgenera diverged 18-39 million years ago whereas species within each subgenus diverged more recently. These results support the current division of Ceanothus into two monophyletic subgenera and agree with the postulated recent divergence of many species within each subgenus. Specificity between Ceanothus species and their Frankia microsymbionts was evaluated by analysis of DNA in nodules collected from three copopulations of Ceanothus species. Sequencing of the intergenic spacer region between 16S and 23S rRNA genes suggested that Ceanothus-microsymbiont Frankia are closely related. Nodules were further analyzed by genomic fingerprinting using repetitive sequences and PCR (rep-PCR). A newly designed, direct repeat sequence and a BOX sequence showed that Ceanothus-microsymbiont Frankia exhibited less diversity within each copopulation than among copopulations. Furthermore, geographic separation was a more important factor for divergence of Ceanothus-microsymbiont Frankia than host plant. The population of Ceanothus-infective Frankia in soils under stands of Ceanothus velutinus and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a non-host plant, were compared. The population sizes were measured using plant bioassay methods with C. velutinus, C. sanguineus, and C. integerrimus as trap plants. Population size in soil under C. velutinus was about 10 times higher than that under the Douglas-fir. Nodulation capacities of the three trap plants were not significantly different. The diversity of Frankia nodulating trap plants was examined using rep-PCR. Results suggested that infective Frankia is not species-specific with regard to the three Ceanothus species used as trap plants and that although the degree of diversity was similar in both soils, the two populations consisted of different Frankia.

For researchers and graduates with any interest in plant or soil sciences, this fascinating study will be a godsend – it’s the complete state of the art with regard to actinorhizal symbioses. The self-contained sixth volume of a comprehensive series on nitrogen fixation, it includes chapters that deal with all aspects of this symbiosis between actinorhizal plants and nitrogen-fixing bacteria. It also contains information both about symbionts and their ecological role and use. Other chapters tackle the global distribution of different actinorhizal plants and their microsymbionts and how this impacts the question of co-evolution of the micro- and macrosymbionts as well as comparing the actinorhizal and leguminous symbioses. No other book provides the up-to-date and in-depth coverage of this volume.

Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

The 12th meeting on Frankia and Actinorhizal Plants that took place in Carry-le-Rouet, France in June 2001 was the opportunity for scientists to communicate about latest developments on this symbiosis that concerns a wide range of dicotyledonous plants, initiates ecological successions and is used in a number of countries to protect crops from winds or improve soil status. Selected papers on plant ecology, Frankia's genetics or physiology, and host plants' genetics or physiology are published in this special Plant & Soil issue.

This book offers a timely overview and synthesis of biogeographic patterns of plants and fungi and their mycorrhizal associations across geographic scales. Written by leading experts in the field, it provides an updated definition of mycorrhizal types and establishes the best practices of modern biogeographic analyses. Individual chapters address the basic processes and mechanisms driving community ecology, population biology and dispersal in mycorrhizal fungi, which differ greatly from these of prokaryotes, plants and animals. Other chapters review the state-of-the-art knowledge about the distribution, ecology and biogeography of all mycorrhizal types and the most important fungal groups involved in mycorrhizal symbiosis. The book argues that molecular methods have revolutionized our understanding of the ecology and biogeography of mycorrhizal symbiosis and that rapidly evolving high-throughput identification and genomics tools will provide unprecedented information about the structure and functioning of mycorrhizal symbiosis on a global scale. This volume appeals to scientists in the fields of plant and fungal ecology and biogeography.
