Fully covers the biology, biochemistry, genetics, and genomics of Medicago truncatula Model plant species are valuable not only because they lead to discoveries in basic biology, but also because they provide resources that facilitate translational biology to improve crops of economic importance. Plant scientists are drawn to models because of their ease of manipulation, simple genome organization, rapid life cycles, and the availability of multiple genetic and genomic tools. This reference provides comprehensive coverage of the Model Legume Medicago truncatula. It features review chapters as well as research chapters describing experiments carried out by the authors with clear materials and methods. Most of the chapters utilize advanced molecular techniques and biochemical analyses to approach a variety of aspects of the Model. The Model Legume Medicago truncatula starts with an examination of M. truncatula plant development; biosynthesis of natural products; stress and M. truncatula; and the M. truncatula-Sinorhizobium meliloti symbiosis. Symbiosis of Medicago truncatula with arbuscular mycorrhiza comes next, followed by chapters on the common symbiotic signaling pathway (CSSP or SYM) and infection events in the Rhizobium-legume symbiosis. Other sections look at hormones and the rhizobial and mycorrhizal symbioses; autoregulation of nodule numbers (AON) in M. truncatula; Medicago truncatula databases and computer programs; and more. Contains reviews, original research chapters, and methods Covers most aspects of the M. truncatula Model System, including basic biology, biochemistry, genetics, and genomics of this system Offers molecular techniques and advanced biochemical analyses for approaching a variety of aspects of the Model Legume Medicago truncatula Includes introductions by the editor to each section, presenting the summary of selected chapters in the section Features an extensive index, to facilitate the search for key terms The Model Legume Medicago truncatula is an excellent book for researchers and upper level graduate students in microbial ecology, environmental microbiology, plant genetics and biochemistry.

Food legumes are important constituents of the human diet and animal feed where they are crucial to a balanced diet, supplying high quality proteins. These crops also play an important role in low-input agricultural production systems by fixing atmospheric nitrogen. Despite systematic and continuous breeding efforts through conventional methods, substantial genetic gains have not been achieved. With the rise in demand for food legumes/pulses and increased market value of these crops, research has focused on increasing production and improving the quality of pulses for both edible and industria.

Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume. Ecological Genomics covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. Ecological Genomics covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.
Molecular and Genetic Study of Plant Resistance to Therioaphis Trifolii in the Model Legume Medicago Truncatula

Aphids are phloem feeding insects that utilize their slender stylets to consume copious amounts of photo-assimilates from plants. The spotted alfalfa aphid (SAA, Therioaphis trifolii) causes severe and widespread damage to important pasture legumes, such as subterranean clover (Trifolium subterraneum) and alfalfa (Medicago sativa) due to direct feeding damage and by vectoring plant viruses. Medicago truncatula, also known as barrel medic, is closely related to alfalfa/lucerne and a host of SAA. M. truncatula has recently been developed to be an important model plant to study plant resistance against various aphids at the physiological, biochemical, and molecular levels. The objectives of this project were to identify the genetic basis and to decipher the defence mechanisms of resistance to T. trifolii in M. truncatula. Three accessions of M. truncatula were identified through my studies and previous work as being useful materials: a highly resistant accession Jester, a moderately resistant accession A17 and a highly susceptible accession A20 to T. trifolii. Among these accessions, I characterised three forms of resistance modalities to T. trifolii, namely antibiosis, antixenosis and tolerance. Moreover, analysis of T. trifolii feeding behaviour using electrical penetration graph (EPG) procedures showed that the proportion of time that the aphids spent on ingesting phloem sap was significantly shorter on Jester and A17 than on A20. These results suggested resistance to T. trifolii is phloem-mediated. The treatment with exogenous salicylic acid, jasmonic acid and ethylene had negative impacts on the feeding of T. trifolii but more on the T. trifolii resistance accessions than the susceptible accession. The genetics underlying T. trifolii resistance in the moderately resistant accession (A17) has also been investigated using 93 recombinant inbred lines (RILs) derived from a cross between A17 and A20 and shown to be controlled by at least 4 quantitative trait loci (QTL). These QTLs have been mapped to 4 individual M. truncatula chromosomes. The results from this research provide fundamental knowledge for future analysis of aphid-plant interactions at the physiological, molecular and genetic levels. Note: Therioaphis trifolii (T. trifolii) is used to refer to both spotted clover aphid (SCA) and spotted alfalfa aphid (SAA). Throughout these chapters, T. trifolii will be referring to SAA for simplicity.

Plant ABC Transporters

This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.
